A catalyst for contact cracking of lower aliphatic alcohols such as methanol to form petroleum type hydrocarbons comprises one or more metals and/or metal ions supported on a phosphate carrier. Preferred metals include transition metals such as Ti, Ni, Cu, Zn, Rh, Ag, Ir and alkali metals, alkaline earth metals, Al and Sn. The phosphate carrier is preferably aluminium phosphate, zirconyl phosphate, magnesium phosphate, barium phosphate, zinc phosphate or a calcium phosphate compound. The metal should amount to 0.1 to 30 % by weight with respect to the phosphate carrier. This catalyst is used to contact crack lower aliphatic alcohols to produce the gasoline type hydrocarbons at a reaction temperature of 200° to 500°C and a supply rate of 0.75 to 3.0 weight units of alcohol per weight unit of catalyst per hour.
