Hydrogen production from cotton stalk over Ni-La catalysts supported on spent bleaching clay via hydrothermal gasification
Recently, master student Mr. Yan-qing Song supervised by Prof. Zhen Fang, collaborated with Dr. A Magdziarz at AGH University of Science and Technology (Poland), Prof. AK Dalai University of Saskatchewan (Canada) and Prof. JA Kozinski at Lakehead University (Canada) published a research article in Industrial Crops & Products about hydrogen production from cotton stalk with Ni-La/ supported on spent bleaching clay (SBC) catalysts.
Cotton stalk was gasified to produce H2 with Ni-La based catalysts in subcritical and supercritical water. Approximately 90% H2 yield was obtained under optimized conditions (360 oC, 0.5 g Ni-La catalyst loading, 0.5 g biomass and 10 min) by an orthogonal design with Ni-La/SBC. In addition, the H2 yield of rice and wheat straw increased by 41.5 and 39.5 times, respectively at optimized conditions. It was found that the activity of Ni-La materials supported with SBC ash and Al2O3 was similar, with H2 yields of 108.3% and 115.1% at 380 oC, respectively in 5 min. Catalysts were characterized by NH3-TPD, TPR, XRD, BET and XPS. SBC ash provided a high specific surface area (94.4 m2/g) for the Ni-La catalyst. La-promoted Ni/SBC (0.19 mmol/g) had a stronger acidity than Ni/SBC (0.16 mmol/g). Ni-La/SBC had a broad reduction peak, indicating the uniform dispersion of Ni on the support. Ni-La/SBC materials not only realized the reuse of SBC but also effectively promoted the hydrothermal gasification of agricultural wastes. Related results were published：

Ni-La materials supported in SBC ash for hydrothermal gasification of cotton stalk with 135.5% H2 yield. (水热条件下Ni-La/废白土催化气化棉花秸秆，H2产率为135.5%。)
水热条件下Ni-La/废白土催化棉花秸秆气化产氢
最近，硕士生宋彦庆在方真老师的指导下，与波兰AGH科技大学A Magdziarz博士, 加拿大Saskatchewan大学 AK Dalai院士以及加拿大Lakehead 大学工学院院长JA Kozinski院士在国际学术期刊 Industrial Crops & Products发表题为“水热条件下Ni-La/废白土催化棉花秸秆气化产氢”的研究性论文。
使用Ni-La基催化剂在亚临界和超临界水中催化气化棉秆生产H2。以Ni-La/废白土（SBC）为催化剂，通过正交实验，筛选出最优反应条件：360 oC、0.5 g Ni-La/SBC、0.5 g 棉杆、10 分钟，获得了约 90% 的 H2 产率。此外，优化条件下水稻和小麦秸秆的H2产量分别提高了41.5倍和39.5倍。同时，发现 SBC 灰和 Al2O3 负载的 Ni-La 材料的活性相似，在 380 oC 下反应 5 分钟的 H2 产率分别为 108.3% 和 115.1%。通过NH3-TPD、TPR、XRD、BET和XPS对催化剂进行了表征。 SBC灰为 Ni-La 催化剂提供了高比表面积 (94.4 m2/g)。La 促进的Ni/SBC (0.19 mmol/g)比Ni/SBC (0.16 mmol/g)具有更强的酸性。Ni-La/SBC 有一个较宽的还原峰，表明 Ni 在载体上均匀分散。Ni-La/SBC材料不仅实现了废白土的再利用，还有效促进了农业废弃物的水热气化。详情可见：
