METHOD OF ISOBUTYLENE PRODUCTION Russian patent published in 2009 - IPC C07C11/09 C07C11/20 B01J29/04

Abstract RU 2351580 C1

FIELD: chemistry.

SUBSTANCE: invention refers to method of isobutylene production by decomposition methyl-tertiary-butyl ether with heterogeneous catalyst at raised temperature and pressure, characterised that catalyst is multi-purpose synthetic zeolite NaX, while process is enables at atmospheric pressure with water vapour with observing the conditions as follows: temperature 200-250°C, volumetric MTBE feed rate 1.0-2.0 h^-1. These conditions ensure minimal generation of MTBE decomposition by-products.

EFFECT: MTBE conversion per run is 96-99% with isobutylene selectivity at least 99%.
