Synthesis of Solid Carbonaceous Acids and Base for Green Production of Biodiesel<\/strong><\/p>\n

Recently, biomass group synthesized carbonaceous acids from dealkaline lignin via solvothermal carbonization, pyrolysis and sulfonation. Carbonization of lignin in sub- and super-critical ethanol provided good surface properties with abundant functional groups (2.81 and 1.35 mmol [H+<\/sup>]\/g) for the subsequent sulfonation to result in high active and stable catalysts for biodiesel production. The synthesized catalysts had high acid content (> 5.05 mmol[H+<\/sup>]\/g), with biodiesel yield > 95% from the esterification of oleic acid at 80 \u25e6C and can be recycled 3-5 times. High biodiesel yield > 90% was obtained from Jatropha and blended soybean oils with high acid values.<\/p>\n

A novel magnetic carbon-based nickel and sodium silicate catalyst (Na2<\/sub>SiO3<\/sub>@Ni\/C) was also prepared by the precipitation of Ni(OH)2<\/sub> on bamboo powders, pyrolysis and the loading of Na2<\/sub>SiO3<\/sub>, and was used in the co-production of biodiesel and hydrogen. Na2<\/sub>SiO3<\/sub>@Ni\/C has high basic content (3.18 mmol\/g) and magnetism (15.7 Am2<\/sup>\/kg), and is stable for 4 cycles with biodiesel yield > 93% and high recovery rate of 85.3% after 5 cycles. With the deactivated Na2<\/sub>SiO3<\/sub>@Ni\/C, 80.1 mol% of crude glycerol gasification rate are achieved with 82.7 mol% H2<\/sub>.<\/p>\n
