PROCESS FOR THE PRODUCTION OF LOWER OLEFINS FROM MIXTURES OF METHANOL AND WATER
摘要
Olefins having from 2 to 4 carbon atoms are manufactured from methanol and/or dimethyl ether in the presence of water and a manganese-containing aluminum silicate catalyst. Before or after application of the manganese, the aluminum silicate is washed with a solution of ethylene-diaminetetraacetic acid or tartaric acid adjusted to a pH of from 3 to 7 by means of a base.
