Red mud supported Ni-Cu bimetallic material for hydrothermal production of hydrogen from biomass<\/strong><\/p>\n

Recently, master student Mr. Gong-xun Xu supervised by Prof. Zhen Fang<\/strong>, collaborated with Dr. S Nanda (Dalhousie University), Profs. AK Dalai (University of Saskatchewan) and Prof. JA Kozinski (Lakehead University published a research article in Industrial Crops & Products about Red mud supported Ni-Cu bimetallic material for hydrothermal production of hydrogen from biomass.<\/p>\n

Exploring efficient and reliable catalysts to achieve gasification of biomass waste is a promising research endeavour. In this study solid waste red mud (RM, an inexpensive and efficient support) loaded Ni-Cu metals (Ni-Cu\/RM) was used to catalyze hydrothermal gasification of cotton stalk at 340-400 \u2103 and 16-30 MPa. In the presence of Ni-Cu\/RM catalyst, 21.88 mmol\/g H2<\/sub> yield with 79.89% carbon balance was achieved, increased by 22.8 times under the optimized conditions (380 \u2103 for 5 min) based on orthogonal experiments. Under the optimal conditions, H2<\/sub> yield with neat Ni and Ni\/RM loaded on RM is 0.96 and 12.94 mmol\/g, respectively due to the specific surface area soaring by 72.0 times from 0.7 to 50.5 m2<\/sup>\/g. With Ni-Cu\/RM bimetallic catalyst, H2<\/sub> yield jumped from 3.41 to 21.88 mmol\/g, 6.7 times higher than that neat Ni, or reached 84% with Ni-Cu\/Al2<\/sub>O3<\/sub> if Al2<\/sub>O3<\/sub> was as support. It is further found that Cu promoted the dispersion of Ni on red mud with surface area rising from 50.47 to 73.42 m2<\/sup>\/g together with forming Ni-Cu alloy (alkalinity of Ni-Cu\/RM rose to 285.65 from 172.21 \u03bcmol\/g for Ni\/RM) enhanced H2<\/sub> generation. When temperature grew from 340 \u2103 (subcritical) to 400 \u2103 (supercritical region), H2<\/sub> yield improved by 3 times from 9.21 to 28.50 mmol\/g. Red mud is an ideal candidate for replacing the commercial support Al2<\/sub>O3<\/sub>.<\/p>\n
