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 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: This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, an olefin compound may be co-fed to the reactor and/or separated from a product stream and recycled to the reactor to improve yield and/or selectivity of certain products. The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used. In some instances, the catalysts are characterized by particle sizes in certain identified ranges that can lead to improve yield and/or selectivity of certain products.

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.
