Synthesis of Magnetic Carbonaceous Solid Acid and Base from Jatropha<\/em> Hulls for the Production of Jatropha<\/em> Biodiesel<\/strong><\/p>\n

\"\"<\/p>\n

Jatropha<\/em> seeds were extracted oil for biodiesel production and the hulls were carbonized to load active sites as magnetic carbonaceous solid acid and base catalysts. Crude Jatropha<\/em> oil was esterified to decrease its acid value to 1.3 from 17.2 mg KOH\/g by the solid acid, and subsequently transesterified to biodiesel (96.7% yield) catalyzed by the solid base. After 3 cycles and magnetically separated, the deactivated base was catalyzed the hydrothermal gasification of biodiesel by-product (crude glycerol) with gasification rate of 81% and 82% H2<\/sub> purity.<\/p>\n

\u00a0\u00a0\u00a0 Recently, biomass group synthesized magnetic carbonaceous solid acid (C-SO3<\/sub>H@Fe\/JHC) and base (Na2<\/sub>SiO3<\/sub>@Ni\/JRC) catalysts by loading active groups on the carbonaceous supporters derived from Jatropha<\/em>-hull hydrolysate and hydrolysis residue. Characterization of their morphology, magnetic saturation, functional groups and total acid\/base contents were performed by various techniques. Additional acidic functional groups that formed with Jatropha<\/em>-hull hydrolysate contributed to the high acidity of C-SO3<\/sub>H@Fe\/JHC catalyst for the pretreatment (esterification) of crude Jatropha oil with high acid values (AV). The AV of esterified Jatropha oil dropped down from 17.2 to 1.3 mg KOH\/g, achieving a high biodiesel yield of 96.7% after subsequent transesterification reaction with Na2<\/sub>SiO3<\/sub>@Ni\/JRC base that was cycled at least 3 times with little loss of catalysis activity. Both solid acid and base catalysts were easily recovered by magnetic force with average recovery yields of 90.3 wt% and 86.7%, respectively. After washed by ethanol, the catalysts were cycled for 10 times. The AV of esterified oil and biodiesel yield using the recycled catalysts remained below 2.0 mg KOH\/g and above 85%, respectively. The existence of catalyst ions and residual methanol contributed to high H2<\/sub> yield (81.0%) and high purity (81.7%) in the hydrothermal gasification of glycerol by-product using the deactivated solid base.<\/p>\n
