The disclosure provides use of an efficient, recyclable, green and friendly catalyst to realize a method of hydrogenation of an unsaturated alkene, and a method for preparing biodiesel through the transesterification of soybean oil with ethanol. The method of hydrogenation of the unsaturated alkene comprises performing a hydrogenation reaction of an unsaturated alkene at ambient temperature and atmospheric pressure by using a CO.sub.2 and magnetic dual-responsive mesoporous poly(ionic liquid) as a catalyst I, and using n-hexane and water as a solvent, to obtain a corresponding saturated alkane. The method for preparing biodiesel through transesterification of soybean oil with ethanol comprises performing a transesterification reaction of soybean oil with ethanol at a temperature of 25-90° C. and atmospheric pressure by using a CO.sub.2 and magnetic dual-responsive mesoporous poly(ionic liquid) as a catalyst II, to obtain the biodiesel.

Surface hydroxyl groups on porous and nonporous metal oxides, such as silica gel and alumina, were metalated with catalyst precursors, such as complexes of earth abundant metals (e.g., Fe, Co, Cr, Ni, Cu, Mn and Mg). The metalated metal oxide catalysts provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of organic transformations. The catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

A process is described for producing paraxylene, in which an aromatic hydrocarbon feedstock comprising benzene and/or toluene is contacted with an alkylating reagent comprising methanol and/or dimethyl ether in an alkylation reaction zone under alkylation conditions in the presence of an alkylation catalyst to produce an alkylated aromatic product comprising xylenes. The alkylation catalyst comprises a molecular sieve having a Constraint Index≤5, and the alkylation conditions comprise a temperature less than 500° C. Paraxylene may then be recovered from the alkylated aromatic product.
