Contacting a mixture of hydrogen, carbon monoxide and/or carbon dioxide with an intimate mixture of a carbon monoxide and/or carbon dioxide reducing catalyst such as a Fischer-Tropsch catalyst, and a catalyst carrier comprising a metal oxide having a very narrow pore size distribution in the micropores within the range of between 10 and 100 Angstroms, to produce hydrocarbon mixtures useful in the manufacture of gasoline kerosene and light oil.

Method for producing hydrocarbons

A process is described for converting glycol dialkyl ether without substantial formation of olefin oligomers by reaction with water, comprising reacting a feed glycol di-tertiary alkyl ether represented by structural formula (A) with water using a strongly acidic cation-exchange resin as a catalyst and a reaction temperature of from 40.degree. C. to 150.degree. C. under a pressure of from 1 to 70 kg/cm.sup.2 (absolute pressure) in a molar ratio of water/feed glycol di-tertiary alkyl ether represented by the structural formula (A) of from 0.05/1 to 60/1, to convert the ether of formula (A) into at least one of (1) glycol mono-tertiary alkyl ether represented by the structural formula (B) and tertiary alcohol represented by the structural formula (C), or (2) glycol mono-tertiary alkyl ether represented by the structural formula (B) tertiary alcohol represented by the structural formula (C) and tertiary olefin represented by the structural formula (D); wherein (A), (B), (C), and (D) are as follows: ##STR1## wherein R.sub.1 represents a methyl group, an ethyl group, or a propyl group, n represents an integer of from 1 to 10, and R.sub.2 represents an alkylene group having from 2 to 14 carbon atoms, and the total number of carbon atoms in the group --(R.sub.2 --O).sub.n -- is from 2 to 30.
