Abstract
Abstract Catalyst for heterogeneous synthesis and more particularly for the preparation of oxygenated compounds from synthesis gas (substantially H 2 and CO and CO 2 ), based on the general formula: CuTi.sub.a M.sub.b A.sub.c in which M is at least one metal selected from the group consisting of chrome, manganese, cobalt, molybdenum, rhodium platinum and iron, A is an alkali or alkaline earth metal, a is comprised within 0.1 and 0.5 and b and c may vary between 0 and 0.2. Application of these catalysts for the preparation of higher alcohol mixtures (fuel grade) C 1 -C 4 when b and c are zero, and C 1 -C 4 (for about 50%) and C 5 -C 10 (for the other 50%) when b and c are other than zero.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A catalyst for the preparation of alcohol mixtures rich in alcohols higher than methanol from a synthesis gas containing H 2 , CO, and CO 2 , consisting essentially of an oxidized alloy of metals according to the formula CuTi.sub.a M.sub.b A.sub.c wherein Cu is copper, Ti is titanium, M is at least one metal selected from the group consisting of chromium, manganese, cobalt, molybdenum, rhodium, platinum, and iron, and A is an alkali metal or an alkaline earth metal; wherein a is 0.1 to 0.5; b is 0.01 to 0.18; and c is 0.01 to 0.18; and a, b, and c represent the molecular proportions of Ti, M, and A, respectively, to Cu; and wherein each of the metals is present in the catalyst in the form of an oxide.
Claim 2
Dependent Claim
131 words
A catalyst for the preparation of alcohol mixtures rich in alcohols higher than methanol from a synthesis gas containing H 2 , CO, and CO 2 , consisting essentially of an oxidized alloy of metals according to the formula CuTi.sub.a M.sub.b A.sub.c wherein Cu is copper, Ti is titanium, M is at least one metal selected from the group consisting of chromium, manganese, cobalt, molybdenum, rhodium, platinum, and iron, and A is an alkali metal or an alkaline earth metal; wherein a is 0.1 to 0.5; b is 0.01 to 0.18; and c is 0.01 to 0.18; and a, b, and c represent the molecular proportions of Ti, M, and A, respectively, to Cu; and wherein each of the metals is present in the catalyst in the form of an oxide.
