Abstract
By catalytic contact with the crystalline alumino-silicate zeolite, mordenite, having a silica to alumina ratio greater than about 15, methanol and/or methyl ethers are catalytically condensed to a mixture of hydrocarbons including polyalkylated aromatic hydrocarbons.
Claims8
A method for converting aliphatic oxygenated organic compounds to hydrocarbon mixtures, which comprises:
- contacting a feed comprising one or more oxygenated organic compounds selected from the group consisting of methanol and methyl ethers of the lower alkanols with a mordenite catalyst having a silica to alumina ratio greater than 15 and a constraint index of less than about 1, said contacting being at a temperature from about 500.degree. F to about 850.degree. F, a pressure of 0.1 atmosphere to 50 atmospheres, and a W.H.S.V. of 0.1 to 30;
- and converting at least about 80% of said oxygenated organic compounds to water and a hydrocarbon mixture containing less than 10 weight percent methane and more than about 50% of C.sub.9, C.sub.10 and heavier aromatics.
