摘要: This invention relates to the catalytic oxidation of ammonia. The catalytic compounds are complex catalysts with limited porosities, with specific surface areas between 0.02 and 2 m2/g, containing an active material bonded by ceramic-type bonds to the elements of a refractory carrier made of refractory oxides such as magnesia, zirconia, silica. Such compounds are suitable for the oxidation of ammonia over fixed beds or fluidized beds.

摘要: Described herein is a method of converting a first alcohol to a second alcohol that includes forming a mixture including a superparamagnetic catalyst and a feedstock, wherein the feedstock includes the first alcohol, and exposing the mixture to a fluctuating magnetic field to form a product, wherein the product includes a second alcohol having a longer carbon chain length than the first alcohol. A flow-through method is described for converting a first alcohol to a second alcohol, wherein the second alcohol has a longer carbon chain length than the first alcohol. Also described is a method of converting glycerol to butanol that includes forming a mixture including a superparamagnetic catalyst and a feedstock, wherein the feedstock includes glycerol, and exposing the mixture to a fluctuating magnetic field to form a product, wherein the product includes butanol. A flow-through method is described for converting glycerol to butanol.

摘要: Described are fluid catalytic cracking (FCC) compositions, methods of manufacture and use. FCC catalyst compositions comprise catalytic microspheres containing a zeolite, a non-zeolitic component, and a rare earth component. The microspheres are modified with phosphorus. The FCC catalyst composition can be used to crack hydrocarbon feeds, particularly resid feeds containing high V and Ni, resulting in lower hydrogen and coke yields.
