Estimating the term…
A process for the oxidation of hydrocarbons comprises contacting the hydrocarbon with an oxygen-containing gas in the presence of a catalyst comprising a microporous solid support, preferably a zeolite, having from 8- to 12-ring open windows and comprising non-framework metal cations selected from manganese, iron, cobalt, vanadium, chromium, copper, nickel, and ruthenium, and mixtures thereof, providing that the oxygen-containing gas does not contain significant amounts of added hydrogen. The catalyst is novel and forms part of the invention. The process may be used for oxidation of alkanes, cycloalkanes, benzene and alkylbenzenes, and is suitable for use in regioselective terminal oxidation of straight chain alkanes and for selective oxidation/separation of p-dialkylbenzenes from an alkylbenzene mixture, for example, p-xylene from an isomeric mixture of xylenes.
A process for the oxidation of hydrocarbons comprising contacting the hydrocarbon with an oxygen-containing gas in the presence of a catalyst comprising a microporous solid support having from 8- to 12-ring open windows and comprising non-framework metal cations selected from manganese, iron, cobalt, vanadium, chromium, copper, nickel, and ruthenium, and mixtures thereof, providing that the oxygen-containing gas does not contain significant amounts of added hydrogen.
A process for oxidation of straight or branched-chain alkanes to produce a product comprising one or more of terminal alcohols, aldehydes, carboxylic acids and ketones comprising contacting the alkane with a catalyst comprising a microporous solid support having 10-ring open windows and comprising non-framework metal cations selected from manganese, iron, cobalt, vanadium, chromium, copper, nickel, and ruthenium, and mixtures thereof, providing that the oxygen-containing gas does not contain significant amounts of added hydrogen.
A process for oxidation of cyclic saturated hydrocarbons having from 5 to 8 carbon atoms or of benzene, optionally substituted by one or more lower alkyl groups, to produce a product comprising a corresponding alcohol, ketone, aldehyde and/or carboxylic acid, comprising contacting the hydrocarbon with an oxygen-containing gas in the presence of a catalyst comprising a microporous solid support having from 8- to 12-ring open windows and comprising non-framework metal cations selected from manganese, iron, cobalt, vanadium, chromium, copper, nickel, ruthenium, and mixtures thereof, providing that the oxygen-containing gas does not contain significant amounts of added hydrogen.
A process for selectively oxidizing a para-dialkylbenzene to produce a product comprising one or more oxygenated derivatives thereof, comprising contacting the dialkylbenzene with a catalyst comprising a microporous solid support having 10-ring open windows and comprising non-framework metal cations selected from manganese, iron, cobalt, vanadium, chromium, copper, nickel, ruthenium, and mixtures thereof, providing that the oxygen-containing gas does not contain significant amounts of added hydrogen.
An oxidation catalyst comprising a microporous solid support having 10-ring open windows, comprising from about 0.01 to about 20 wt. % of non-framework manganese cations.
