Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
109 words
IN A PROCESS FOR THE SYNTHESIS OF HYDROCARBONS AND OXYGENATED HYDROCARBONS BY THE CATALYTIC INTERACTION OF SYNTHESIS REACTANTS COMPRISING CARBON MONOXIDE AND HYDROGEN IN SYNTHESIS PROPORTIONS, THE IMPROVEMENT WHICH COMPRISES PASSING THE SYNTHESIS REACTANTS AT A SYNTHESIS REACTION TEMPERATURE IN THE RANGE OF ABOUT 375 TO 396*F. INTO CONTACT WITH A CATALYST COMPRISING COBALT AND A COMPOSITE SUPPORTING MATERIAL CONSISTING ESSENTIALLY OF APPROXIMATELY EQUAL PROPORTIONS BY WEIGHT OF UNCALCINED DIATOMACEOUS EARTH, AND ALUMINA CONTAINING LESS THAN ABOUT 0.8 PERCENT BY WEIGHT OF ALKALI METAL COMPOUNDS, EXPRESSED ON THE BASIS OF EQUIVALENT SODIUM OXIDE, STABILIZED WITH ABOUT 5 WEIGHT PERCENT SILICA, SAID CATALYST COMPRISING A PROMOTOR FOR THE SYNTHESIS REACTION.
