Title: Zeolitic catalytic conversion of alochols to hydrocarbons

Abstract

A method for converting an alcohol to a hydrocarbon, the method comprising contacting said alcohol with a metal-loaded zeolite catalyst at a temperature of at least 100.degree. C. and up to 550.degree. C., wherein said alcohol can be produced by a fermentation process, said metal is a positively-charged metal ion, and said metal-loaded zeolite catalyst is catalytically active for converting said alcohol to said hydrocarbon.

  • A method for converting an alcohol to a hydrocarbon, the method comprising contacting said alcohol with a metal-loaded zeolite catalyst at a temperature of at least 100.degree. C. and up to 550.degree. C., wherein said alcohol can be produced by a fermentation process, said metal is a positively-charged metal ion, and said metal-loaded zeolite catalyst is catalytically active for converting said alcohol to said hydrocarbon.
  • This patent describes a continuous catalytic process for the production of higher molecular weight hydrocarbons from methane in which a methane-containing gas containing less than 1 volume percent other hydrocarbons is contacted in a reaction zone with a higher molecular weight hydrocarbon synthesis catalyst under C/sub 2/+ hydrocarbon synthesis conditions. The improvement comprising increasing the reaction rate of the methane-containing gas by a factor of 1.4 to 4.0 by adding a C/sub 2/ to C/sub 4/ hydrocarbon to the gas and increasing the yield of light aromatic hydrocarbons by 10 to 40 weight percent by adding hydrogen to the gasmore » thereby forming a reaction gas. The C/sub 2/ to C/sub 4/ hydrocarbon comprises 0.1 to 10 volume percent of the reaction gas and the hydrogen comprises 1 to 25 volume percent of the reaction gas, the synthesis conditions including a temperature greater than 1000/sup 0/C and a gas hourly space velocity of greater than 3200 hr/sup -1/.« less
  • The process comprises contacting hydrocarbon distillate with a cracking catalyst at catalytic cracking conditions and separating the gas and gasoline. The gasoline is separated into a low-boiling and a high-boiling fraction, and the gaseous products are separated into a plurality of fractions, one of which comprises essentially hydrogen and uncondensable hydrocarbon gases and another a fraction comprising essentially C/sub 3/ and C/sub 4/ hydrocarbons. The C/sub 3/ and C/sub 4/ olefins in the fraction are catalytically polymerized, and the polymers thereof boiling within the gasoline boiling range are combined with the aforesaid low-boiling fraction of gasoline from the catalytic crackingmore » step and the hydrogen-containing gas from the cracking step. This mixture is contacted with a hydrogenation catalyst at hydrogenating conditions, and the recovered hydrogenated product is blended with the high-boiling gasoline fraction from the catalytic cracking step.« less
