A new Springer book “Production of N-containing Chemicals and Materials from Biomass” was published.

Recently, Springer has published a book entitled “Production of N-containing Chemicals and Materials from Biomass” edited by Profs. Zhen Fang, Richard L. Smith Jr., and Dr. Lujiang Xu, Springer, Hardcover •ISBN 978-981-99-4579-5, 414 pages, 2023.

(https://link.springer.com/book/10.1007/978-981-99-4580-1).

 

N-containing chemicals and carbon materials are a class of important heterocyclic compounds and materials with wide applications. Biomass, especially lignocellulose, is currently the only renewable carbon resource. This book is a collection of studies on state-of-art techniques developed for producing value-added N-containing chemicals and N-doped carbon materials from renewable sources via sustainable technologies. Aiming to improve conversion effectiveness and develop innovative techniques for new value-added N-containing products, topics in the text address recent advances, assess and highlight promising methods or technological strategies, and outline direct conversion routes for conversion of renewable resources to N-containing chemicals and materials.

 

This book contains 12 chapters contributed by leading experts in the field. The text is arranged into four key areas:

Part I: Production of N-Containing Compounds by Chemical Catalytic Processes (Chapters 1-6)

Part II: Production of N-Containing Compounds via Biological Processes (Chapters 7)

Part III: Application of N-containing Biomass to Manufacture of Chemicals and Materials (Chapters 8-11)

Part IV: N Transformations During Thermal Processes (Chapter 12)

Producing N-containing chemicals and materials from renewable sources has a bright future and will be a potential choice for replacing the fossil-based chemicals and material. Offering comprehensive information on the production of N-containing chemicals and their use in the manufacture of materials from biomass, the book represents a valuable choice for students, researchers, academicians and industrialists in the field of biochemistry and energy.

This book is the 12th book of the Springer series entitled, “Biofuels and Biorefineries” (Prof. Zhen Fang is serving as editor-in-Chief).

Sustainable production of aromatic-rich biofuel via catalytic co-pyrolysis of lignin and waste polyoxymethylene over commercial Al₂O₃ catalyst

Recently, under the guidance of Associate Professor Lu-jiang Xu, master student Mr. Ge-liang Xie published an article on the preparation of high aromatic biofuels by lignin and waste polyoxymethylene (POM) catalytic co-pyrolysis in the journal Journal of Analytical and Applied Pyrolysis.

Co-valorization of biomass and multiple solid wastes is essential to environment protection and energy security. Herein, aromatic-rich biofuel was produced from lignin and waste polyoxymethylene (POM) via catalytic co-pyrolysis process. Commercial and cheap γ-Al₂O₃ catalyst exhibited good catalytic performance. Series characterizations and bench-top pyrolysis experiments were conducted to illustrate the synergism between raw materials and the mechanism of aromatics formation. The TG analysis and thermodynamics calculation revealed that a remarkably positive synergistic effect existed between lignin and POM, could reduce the activation energies, and make the reaction more conducive in terms of thermodynamics. Meanwhile, the yields of biochar and bio-oil increased considerably Additionally, the operating conditions affected the product distributions significantly. The suitable mixing ratio of lignin to POM was around equal (5:5) with the bio-oil yield increased by 25% to 28.3% and aromatic hydrocarbons selectivity increased to >95%. Moreover, POM, the precursor for alkylating reagents and hydrogen donors, could promote the deoxygenation reactions of phenolic intermediates and result into aromatic hydrocarbons. The acid sites of γ-Al₂O₃ promoted series secondary cracking reactions (alkylation, deoxygenation), and thus improve bio-oil quality. Finally, the stability test showed that commercial γ-Al₂O₃ catalyst was slightly deactivated after 4 cycles because of coke deposits and acid sites loss.

Related results were published in Journal of Analysis and Applied Pyrolysis:

GL Xie, GQ Zhu, T Lv, YF Kang, YH Chen, Z Fang, LJ Xu*, Sustainable production of aromatic-rich biofuel via catalytic co-pyrolysis of lignin and waste polyoxymethylene over commercial Al₂O₃ catalyst, Journal of Analytical and Applied Pyrolysis, 174, 106147, https://authors.elsevier.com/c/1hiQybaW~3r4b (2023).

Using lignin and waste acetal (POM) as raw materials and commercial γ-Al₂O₃ as catalyst, aromatic-rich biofuels were prepared by catalytic co-pyrolysis process. The suitable mixing ratio of lignin and polyoxymethylene was about 5∶5, the yield of bio-oil increased by 25% to 28.3%, and the selectivity of aromatic hydrocarbons increased to >95%.以木质素和废聚甲醛（POM）为原料，商业γ-Al₂O₃作为催化剂，采用催化共热解工艺制备了富含芳烃的生物燃料。在木质素与聚甲醛的适宜混合比例下（5∶5），生物油收率提高了25%至28.3%，芳烃选择性提高至>95%。

通过商业Al₂O₃催化剂催化木质素和废聚甲醛的共热解可持续生产富含芳烃的生物燃料

近日，在徐禄江副教授的指导下，硕士生谢葛亮先生在《分析与应用热解杂志》（IF 6.0）上发表了一篇关于木质素与废聚甲醛催化共热解制备高芳烃生物燃料的研究性论文。

生物质和多种固体废物的联合定价对环境保护和能源安全至关重要。以木质素和废聚甲醛（POM）为原料，采用催化共热解工艺制备了富含芳烃的生物燃料。市售廉价的γ-Al₂O₃催化剂具有良好的催化性能。通过系列表征和台架热解实验，阐明了原料之间的协同作用和芳烃的形成机理。TG分析和热力学计算表明，木质素与聚甲醛之间存在显著的正协同作用，可以降低活化能，使反应在热力学上更有利于进行。同时，生物炭和生物油的产率显著提高，操作条件对产物分布有显著影响。木质素与聚甲醛的适宜混合比例约为5∶5，生物油收率提高了25%至28.3%，芳烃选择性提高至>95%。此外，POM作为烷基化试剂和氢供体的前体，可以促进酚类中间体的脱氧反应，生成芳烃。γ-Al₂O₃的酸性位点促进了一系列的二次裂化反应（烷基化、脱氧），从而提高了生物油的质量。最后，稳定性测试表明，商业γ-Al₂O₃催化剂在4次循环后由于焦炭沉积和酸位损失而轻微失活。

结果发表在Journal of Analysis and Applied Pyrolysis:

Two-stage process production of microbial lipid by co-fermentation of glucose and N-acetylglucosamine from food wastes with Cryptococcus curvatus

Recently, master student Mr. Jia-xuan Zhang supervised by Prof. Zhen Fang published a research article in Bioresource Technology about Two-stage fermentation of food waste (rice and shrimp shells hydrolysates) by Cryptococcus curvatus for lipids.

Microbial lipids were produced through a two-stage process with Cryptococcus curvatus by co-fermenting rice and shrimp shells hydrolysates. The main components of the lipid sample were long-chain fatty acids with carbon chain lengths of 16 and 18, which were similar to those of typical vegetable oils. And the lipid sample showed high potential for biodiesel production. In the shake flask fermentation, co-utilization of N-acetylglucosamine (GlcNAc) and glucose resulted in improved cell mass and lipid production. The highest cell concentration of 17.60 g/L was achieved in the first-stage, and the highest lipid yield was 0.233 g/g in the second- stage. Scaling up to a 5-L bioreactor increased lipid content to 60.07 % with 0.233 g/g yield. When Cryptococcus curvatus was cultured in the blends of rice hydrolysates and shrimp shells hydrolysate, lipid content and yield were 52.25 % and 0.204 g/g. Co-fermentation of rice hydrolysates and chitin hydrolysate is an effective means for recycling food wastes for lipids.

Related results were published in Bioresource Technology:

Two-stage process production of microbial lipid by co-fermentation with rice and shrimp shells hydrolysates from food wastes was carried out. After 36 h of the first-stage fermentation, 12.51 g/L of glucose and 9.91 g/L of GlcNAc were consumed simultaneously with 12.18 g/L cell mass produced. Transferring 6 g/L of yeast cells to the second-stage fermentation medium, cell mass of 19.44 g/L, lipid content of 52.25 %, and lipid yield of 0.204 g/g were obtained, respectively. (以食品废弃物中的大米水解物和虾壳的水解物为原料，采用两阶段共发酵工艺生产微生物油脂。在第一阶段发酵36 h后，12.51 g/L 葡萄糖和9.91 g/L N -乙酰氨基葡萄糖被消耗，细胞产量为12.18 g/L。然后将6g/L的酵母细胞转移到第二阶段发酵培养基中。分别获得19.44g/L的细胞质量、52.25%的脂质含量和0.204g/g的脂质产率。

Cryptococcus curvatus共发酵食品废弃物中葡萄糖和N –乙酰氨基葡萄糖两阶段工艺生产微生物脂质

最近，硕士生张家璇（男）在方真教授的指导下，在国际学术期刊Bioresource Technology （Q1, IF 11.4）发表一篇关于两阶段共发酵来自食品废弃物的葡萄糖和N-乙酰氨基葡萄糖生产微生物油脂的研究性论文。

以Cryptococcus curvatus 为研究对象，通过共发酵大米水解物和虾壳的水解物，利用两阶段工艺制备微生物脂质。脂质样品的主要成分是碳链长度为16和18的长链脂肪酸，与典型的植物油相似。脂质样品显示出生产生物柴油的较高潜力。在摇瓶发酵中，N-乙酰氨基葡萄糖（GlcNAc）和葡萄糖的共同利用提高了细胞质量和脂质产量。在第一阶段达到17.60g/L的最高细胞浓度，在第二阶段达到0.233g/g的最高脂质产率。扩大至5-L生物反应器发酵，可将脂质含量提高到60.07%，产量为0.233g/g。Cryptococcus curvatus在大米水解物和虾壳水解物的混合物中培养时，脂质含量和产量分别为52.25%和0.204g/g。大米水解物和甲壳素水解物的联合发酵是回收食品垃圾的有效途径。
