CATALYST FOR OBTAINING ETHYLENE AND METHOD OF OBTAINING ETHYLENE WITH APPLYING THEREOF Russian patent published in 2014 - IPC B01J23/10 B01J27/22 C07C2/84 B01J21/08 

FIELD: chemistry.

SUBSTANCE: catalyst contains an active phase, which represents a mixture of cerium oxide (CeO₂) and lanthanum oxide (La₂O₃) or cerium oxide (CeO₂) and lanthanum oxide (La₂O₃), applied on a silicon dioxide carrier (SiO₂), and a metal carbide-based inert material, actively absorbing SHF energy, taken in a weight ratio of the active phase and metal carbide (2-4):1, respectively. As metal carbide it contains tungsten, tantalum or niobium carbide. Also claimed is a method of obtaining ethylene by oxidative condensation of methane in the presence of the claimed catalyst. The process is carried out in a flow reactor at atmospheric pressure with contact of a stationary catalyst layer, heated to a temperature of 750-800°C in SHF radiation with power to 45 W, with a flow of a methane-air mixture, with a ratio of CH₄/O₂ in the range 2-7/1, with a rate of gas raw material supply in the range 40-150 ml/min and a charge of catalyst of 300 mg.

EFFECT: creation of highly efficient catalyst, capable of working under conditions of SHF radiation and making it possible to increase selectivity to ethylene and the process productivity, and reduce its energy consumption.
