Abstract: Disclosed is a Lewis acid catalyst for preparation of toluene from 2-methylfuran and a method for preparing toluene from 2-methylfuran by using the same. The catalyst is a zeolite catalyst ion-exchanged with a metal or a metal halide catalyst. The catalyst accelerates the cycloaddition of 2-methylfuran with ethylene and inhibits oligomerization as a side reaction, and thus allows production of toluene from 2-methylfuran with high yield and high selectivity.

Abstract: The present disclosure relates to catalysts supported on a modified-carrier for oxidative coupling reaction of methane and a method for oxidative coupling reaction of methane using the same. The catalysts in which sodium tungstate is supported on a delaminated zeolite carrier increase the methane conversion rate and the selectivity to C2+ hydrocarbon compounds and thereby improve the reactivity of the oxidative coupling reaction of methane.

Abstract: Disclosed is a method for producing glycidol by successive catalytic reactions. The method includes a series of reactions for the preparation of glycerol carbonate from glycerol and the decarboxylation of the glycerol carbonate. Specifically, the method includes i) reacting glycerol with a dialkyl carbonate to prepare glycerol carbonate, and ii) subjecting the glycerol carbonate to decarboxylation wherein a base is added as a catalyst in step i) and is allowed to react with an acid to form a metal salt after step i), and the salt is used as a catalyst in step ii). According to the method, inexpensive and easy-to-purchase acid and base catalysts can be used to produce glycidol from glycerol, a by-product of biodiesel production, as a starting material in high yield with high selectivity in a convenient, simple, and environmentally friendly way. In addition, the method eliminates the need to separate the base catalyst.
