METHOD OF CATALYTIC METHANE OXYCHLORINATION

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a method of catalytic methane oxychlorination in a deck-type adiabatic reactor under pressure of 1-10 atm in presence of a catalyst, which contains on a porous carrier with a specific surface of 1-60 m/g a mixture of copper, potassium and lanthanum chlorides in a molar ratio of 1:1:0.3 in an amount of 3-30 wt % of the carrier weight and distributed on each reactor deck by 30% higher than the previous one. The two-layered catalyst in the form of equal in volume layers is loaded into the deck-type adiabatic reactor by a flow of reaction gas on each deck of the adiabatic reactor, the first layer of the catalyst contains a mixture of copper, potassium and lanthanum chlorides in a molar ratio of 1:1:0.3, and the second layer of the catalyst - a mixture of copper and potassium chlorides in a molar ratio of 1:1.EFFECT: conversion of hydrogen chloride remains stable when the claimed method is applied.1 ex, 1 tbl
