Abstract
The preparation of alcohols from synthesis gas has been beneficiated by the use of a novel five-component catalyst system comprising an iron group metal and an activity improving amount of a precious metal such as rhodium.
Claims8
A process for the production of alcohols from synthesis gas which comprises contacting a synthesis gas under suitable reaction conditions with a catalyst consisting of:
- (a) at least one copper component,
- (b) at least one iron group metal component,
- (c) at least one metal component other than compounds (b) having a Periodic element number of 23 to 26,
- (d) at least one alkali metal component, and
- (e) a promoting amount of about 0.1 to about 5 weight percent of at least one rhodium component, which promoting amount is a small effective amount sufficient to increase catalyst activity and catalyst life without significantly changing selectivity in comparison with the unpromoted catalyst.
2 more elements
A process for preparing alcohols from synthesis gas comprising the step of contacting synthesis gas feed with a catalyst consisting of the following elements:
- (a) about 15 to about 70 weight percent copper,
- (b) about 5 to about 50 weight percent cobalt,
- (c) about 5 to about 50 weight percent of at least one element selected from chromium, iron, vanadium, and manganese,
- (d) about 0.1 to about 10 weight percent of an alkali metal, and
- (e) about 0.1 to about 5 weight percent rhodium.
