热解产芳香胺: Aromatic amines from pyrolysis of lignin and phenol-formaldehyde resins

Recently, Dr. Lujiang Xu together with Prof. Zhen Fang published a paper in “Bioresource Technology” about the production of aromatic amines from phenol-formaldehyde resins and lignin via co-catalytic pyrolysis with ammonia process.

Aromatic amines could be produced from organic wastes via catalytic pyrolysis with ammonia that served not only as a carrier gas but also as a reactant. Aromatic amines of 14.2 C% with selectivity of 57.6 % were obtained from phenol-formaldehyde (PF) resins via pyrolysis over commercial HZSM-5-3 zeolite (Si/Al ratio of 80) catalyst at 650 °C. Significant synergetic effects have been observed when lignin was added, which improved aromatic amines yield by 32.2 % to 11.8 C% at the mixing weight ratio of lignin to PF resins of 1:1. HZSM-5-3 was slightly deactivated after 3 cycles with acid sites loss. Catalytic co-pyrolysis of plastics and biomass wastes is a fast and effective method to produce aromatic amines.

Aromatic amines was produced from PF resins with 14.2 C% yield and 58% selectivity. Co-pyrolysis was effectively enhance aromatic amines yield by 32.2%. (酚醛树脂通过氨气氛围催化热解可以生产14.2%碳产率的芳香胺;与木质素共热解,酚醛树脂可以提高芳香胺产率32%)

徐禄江博士在国际学术期刊Bioresource Technology发表学术论文


最近,农业工程TOP期刊Bioresource Technology(影响因子7.54, Q1,第一署名单位为南京农业大学,第一作者为徐禄江博士,通讯作者为方真教授)发表了废弃塑料酚醛树脂和木质素通过氨气氛围催化热解的方式生产芳香胺的文章。

芳香胺(如苯胺等)是一类重要的大宗化工原料。利用氨作为载气和反应气体,通过催化裂解的方法转化有机废物(酚醛树脂和木质素)生产芳香胺。以工业用HZSM-5-3(Si/Al=80)沸石分子筛为催化剂在650℃高温下裂解酚醛树脂,可以得到了14.2 C%的芳香胺,且产物中芳香胺选择性达到57.6%。当木质素与酚醛树脂的混合重量比为1:1时,添加酚醛树脂可使芳香胺的产率提高32.2%。催化剂在3个循环后由于酸位点损失导致略有失活。由此可见,氨气氛围下的废弃塑料与木质素废料催化共热解也是一种可以快速制备芳香族胺的有效方法。

书奖:Winning 2020 Springer-Nature China New Development Awards

The Springer book “Production of Materials from Sustainable Biomass Resources” (2019) edited by Zhen Fang*, RL Smith, Jr, XF Tian, wins  the prestigious ‘Springer-Nature China New Development Awards‘ in 2020. Springer Nature granted “China New Development Awards” to the Chinese authors of 10 scholarly books selected from the 1000 books published in 2019 in recognition of their exceptional contributions to the delivery of the UN Sustainable Development Goals (SDGs).

In September 2015, the 193 Member States of the United Nations adopted the 2030 Agenda for Sustainable Development, calling for action by all countries to achieve the 17 Sustainable Development Goals by 2030. The 2030 Agenda provides a framework for all governments, businesses, organizations and society to work together to solve the world’s biggest challenges, such as poverty, inequality, climate change, environmental degradation, and peace and justice. Springer Nature, one of the world’s leading academic publishers, supports delivery of the SDGs through its publishing programme by sharing the discoveries that address the challenges of sustainable development. 

Dr. Linxiu Zhang (Director UNEP-IEMP) congratulates the winning authors and expresses her expectation for the future awards. Dr. Niels Peter Thomas (Managing Director, Books, Springer-Nature) and Mr. Arnout Jacobs (Managing Director,Greater China) explain the value of these Awards as well as praise the achievements in sustainable development research from China. 

Academic books are used by authors to summarize and share their long-term research findings at a certain stage of their careers. Compared with journal papers, they are more complete and comprehensive in topic coverage, and are written more systematically. They also feature a longer shelf life; in particular, some classics on fundamental research and works used as textbooks remain long-standing because of their enduring academic and ideological values. Therefore, academic books have their unique role and advantage in helping understand and solve complicated, sustainability issues spanning across different aspects of knowledge.

Microbial Lipid Production from Both Rice Straw Hydrolysates and Recycled Pretreated Glycerol

Microbial Lipid Production from Both Rice Straw Hydrolysates and Recycled Pretreated Glycerol

Recently, PhD student Mr. Song Tang supervised by Prof. Zhen FANG produced microbial lipid from both rice straw hydrolysates and recycled pretreated glycerol. First, lipid fermentation of glucose via Cryptococcus curvatus was optimized by response surface methodology. Variables were selected by Plackett–Burman design, and optimized by central composite design, achieving 4.9 g/L total lipid and 0.16 g/g lipid yield, and increased further as glucose increased from 30 to 50 g/L. It was found that lipid content rapidly decreased from 44.5% to 6.4% as lignin (0.5 g/L) was added, which would inhibit lipid accumulation for hydrolysate and recycled glycerol. Secondly, these fermentation conditions were further used for rice straw hydrolysates. After glycerol-FeCl3 pretreatment (0.06 mol/L FeCl3, 150 °C and 20 min), 72% lignin of rice straw was removed with glucose yield increased by 2.4 times to 74.3% at 20% substrate loading and 3 FPU/g dry substrate. Its hydrolysates were separated for lipid fermentation, producing high total lipid (8.8 g/L) and lipid yield (0.17 g/g). Finally, recycled glycerol reached the maximum total lipid of 7.2 g/L and high lipid yield of 0.16 g/g. Based on the calculation, 2.9 g total lipid would be produced from 1 g rice straw and the recycled glycerol, with a similar composition to soybean oil.

The results were published:

Microbial lipid production from both rice straw hydrolysates and recycled pretreated glycerol(水稻秸秆经甘油-氯化铁预处理后,酶水解,将秸秆水解产物和预处理液中纯化的甘油作为碳源,通过弯曲隐球菌高效生产油脂。)



 最近,博士生唐松(男)同学在方老师的指导下,利用稻秆水解液和预处理液中纯化的甘油发酵生产微生物油脂。首先,通过响应面优化弯曲隐球菌发酵葡萄糖产油脂,通过Plackett-Burman实验筛选出显著性因素,设计中心组合实验以优化油脂产量,在最佳发酵条件,总油脂量为4.9 g/L,油脂产率达到0.16 g/g,并通过增加葡萄糖浓度以进一步提高了其产油脂量。但在添加木质素(0.5 g/L)后,酵母胞内油脂含量从44.5%迅速降低至6.4%,这表明木质素会抑制胞内油脂的积累。此后,在优化的发酵条件下,利用稻秆水解产物发酵产微生物油脂。通过甘油-氯化铁预处理(150 °C 和 20 min),稻秆中72%木质素被去除,酶解率较未处理前提高了2.4倍。在3 FPU/g干基和20%基质浓度条件下,酶水解72 h后,预处理后稻秆的酶解率高达74.3%。基于响应面优化的最佳葡萄糖产油脂的发酵条件,在将分离的秸秆水解产物作为碳源,产出油脂8.8 g/L,同时油脂产率也达到了0.17 g/g。最后,利用预处理液中纯化的甘油发酵生产微生物油脂,总油脂量最高达到7.2 g/L,并获得了高水平的油脂产率(0.16 g/g)。通过物料质量平衡分析,1 g稻秆及其预处理中所用甘油将产出2​​.9 g油脂,其脂肪酸组成也相似于大豆油。

Editorial “Catalytic Biomass to Renewable Biofuels and Biomaterials”

Dr. Yi-Tong Wang (Associate Prof. at North China University of Science and Technology in Tangshan) and Prof. Zhen Fang as guest editors for the Special Issue “Catalytic Biomass to Renewable Biofuels and Biomaterials” in Catalysts (ISSN 2073-4344) wrote an editorial about catalytic conversions of biomass. Renewable, clean and environmentally friendly biofuels and biomaterials applications are in line with the healthy development of the world’s energy and materials in the future. Biomass as the only renewable carbon source on Earth has been proposed as an ideal alternative to fossil resources and can be catalytically conversed to valuable products, such as hydrolysis of lignocellulosic wastes, synthesis of biodiesel and bioethanol, thermal conversions of biomass and organic wastes. This special issue contains 11 papers (1 review and 10 research articles) contributed by leading experts in the field. The articles include: catalytic conversion of glycerol to acetyl derivatives, base-catalyzed organosoly process to fractionate European larch to recover cellulose and pure lignin, co-pyrolysis of grape seeds and waste tires for bio-oils in a pilot-scale auger reactor with Ca-based catalysts, diesel and jet fuel cycloalkanes produced from cyclopentanone and furfural, macroporous cross-linked copolymers from wheat straw, 2,5-bis(hydroxymethyl)furan from hydroxymethylfurfural, N-containing chemicals from polyethylene terephthalate via catalytic fast pyrolysis with ammonia, co-combustion of sludge and wheat straw, biofuels from fermentation of gases by Clostridium carboxidivorans, humic acid-rich composts for applications to catalyzing redox-mediated reactions of pollutants in soils, a review on some organisms such as Clostridium carboxidivorans, C. ragsdalei, and C. ljungdahlii for the production of biofuels (e.g., ethanol and butanol) and chemicals.

These papers should be of interest to professionals in academia and industry who are working in the fields of natural renewable materials, biorefinery of lignocellulose, biofuels and environmental engineering. It can also be used as comprehensive references for university students with backgrounds of catalysis, agricultural engineering, chemical engineering, material science and environmental engineering.

Subcritical water gasification of lignocellulosic wastes for hydrogen production with CoNi/Al2O3

Subcritical water gasification of lignocellulosic wastes for hydrogen production with CoNi/Al2O3

Recently, master student Mr. Jie Sun supervised by Prof. Zhen Fang collaborated with Profs. JA Kozinski at Waterloo and AK Dalai at U of Saskatchewan in Canada, published a research article in J Supercrit Fluids about hydrogen production from lignocellulosic wastes with CoNi/Al2O3 catalysts.

Nickel-based catalysts with different supports and cobalt loadings were synthesized for hydrothermal gasification of cellulose 350 oC. The activity of Ni catalysts was found in the order of Al2O3 > spent bleaching clay ash > SiO2 with H2 yield of 80.6%, 69.0% and 57.0% and the prepared catalyst using Al2O3 as the support showed the highest catalytic activity to produce H2. When 6 wt. % Co was added, H2 yield reached the maximum value of 88.4%, which was 1.44 times than that of 10Ni/Al2O3 catalyst without adding Co. Catalysts were characterized by NH3-TPD, TPR, XRD, BET and XPS, showing that Ni-Co alloy formation promoted H2 production. Furthermore, the effect of parameters such as feedstock usage and residence time were also investigated systematically with 10Ni-6Co/Al2O3 catalyst and the results indicated that the optimal yield of H2 at 94.9% was obtained at the conditions of 0.5g cellulose usage and 20 min residence time. Finally, the study about different lignocellulosic wastes (rice straw, peanut shells and cotton straw) with the increase in H2 yield by 51.4, 76.0 and 67.8 times and cotton straw obtained the highest H2 yield of 82.6%.

Catalytic hydrothermal gasification of cotton straw with H2 yield of 82.6% over NiCo/Al2O3 catalyst at 350 oC and 20 min.(NiCo/Al2O3催化剂在350 oC和20 min条件下催化棉花秸秆水热气化, H2产率为82.6%。)


最近,硕士生孙杰在方老师的指导下,与加拿大滑铁卢大学JA Kozinski院士和萨斯卡彻温大学AK Dalai院士合作,在国际学术期刊J Supercrit Fluids发表以Co改性Ni/Al2O3催化剂从木质纤维素废弃物中制取氢气的研究性论文。

合成了具有不同载体和钴载量的镍基催化剂,用于350 oC条件下纤维素的水热气化。 Ni催化剂的活性根据载体来排序依次为Al2O3、SBC ash (废白土灰)、SiO2,对应的H2产率分别为80.6%,69.0%和57.0%,且以Al2O3作为载体制备的催化剂具有最高的产氢催化活性。当Co的负载量为6 wt. %时,H2产率达到最大值,为88.4%,是不添加Co的10Ni/Al2O3催化剂H2产率的1.44倍。NH3-TPD,TPR,XRD,BET和XPS等特征分析,表明Ni-Co合金的形成促进了H2的产生。此外,还以10Ni-6Co/Al2O3作为催化剂研究了原料用量和停留时间等参数的影响,结果表明,在纤维素用量和停留时间分别为0.5 g和20 min的条件下,H2产率进一步提高到94.9%。最后,对不同木质纤维素废弃物(水稻秸秆、花生壳和棉花秸秆)的气化进行了研究,H2产率分别提高了51.4、76.0和67.8倍,而棉秸秆获得最高的H2产量为82.6%。 Ni-Co/Al2O3催化剂促进了木质纤维素废弃物水热气化产氢。详情可见:
