Abstract:
A method is provided for treating hydrocarbons containing chemically combined chlorine by passing the hydrocarbons through a bed of molecular sieves of effective pore size in the range of 7 to 11 Angstrom units to remove the chemically combined chlorine and other impurities.
Abstract:
Ethylene is upgraded to hydrocarbons of higher molecular weight by contact with a catalyst comprising an olefin dimerization component and an olefin disproportionation component.
Abstract:
OLEFINS ARE CONVERTED INTO OTHER OLEFINS HAVING DIFFERENT MOLECULAR WEIGHTS BY CONTACT WITH A CATALYST ACTIVE FOR DISPROPORTIONATING PROPYLENE INTO ETHYLENE AND BUTENE AND WITH MAGNESIUM OXIDE WHICH HAS BEEN TREATED WITH CARBON MONOXIDE, NITRIC OXIDE, HYDROGEN OR AN OLEFINIC OR A PARAFFINIC HYDROCARBON AT ELEVATED TEMPERATURE.
Abstract:
A catalyst for the olefin disproportionation of unsaturated hydrocarbons is provided comprising a physical mixture of a solid disproportionation catalyst and a double bond isomerization catalyst wherein the double bond isomerization catalyst is further treated with a base.
