Abstract

The invention relates to long chain alcohol, to processes for catalytically producing long chain alcohol from carbon monoxide and molecular hydrogen, to equipment useful in such processes, and to the use of long chain alcohol, e.g., for producing fuel, lubricating oil, detergent, and plasticizer. The catalyst is mesoporous and comprises iron and copper.

First claim

The invention claimed is:

1. A reaction effluent comprising a long chain alcohol produced by the process comprising:
(a) providing a feed mixture comprising molecular hydrogen and ≥0.01 wt. % of carbon monoxide, the feed mixture having a molecular hydrogen to carbon monoxide molar ratio in the range of from 0.01 to 100;
(b) providing at least one templated multi-metallic, mesoporous catalyst comprising copper, ≥0.5 wt. % of iron, ≤1.0 wt. % of CuO and ≤1.0 wt. % of Fe 3 O 4 , wherein the templated active material's template is produced from a carbonaceous structure-directing agent, the carbonaceous structure-directing agent comprising one or more of siloxane, urea, and surfactant, the catalyst having
(i) an iron to copper molar ratio in the range of from 0.1 to 10,
(ii) a plurality of pores having an average pore size in the range of from 2 nm to 50 nm, and
(iii) an average surface area ≥50 m 2 /g; and
(c) reacting at least a portion of the feed mixture's carbon monoxide and at least a portion of the feed mixture's molecular hydrogen in the presence of the catalyst to produce a reaction effluent comprising long chain alcohol, the reaction conditions including a reaction temperature ≥150° C., a total pressure ≥100 psig, and a space velocity (GHSV) ≥50 hr −1 ,
wherein the reaction conditions further comprise conversion of 45 wt. % or more of the feed mixture's carbon monoxide, and
wherein the reaction conditions further comprise a selectivity for formation of 1-alcohol of 40 wt. % or more relative to the weight of converted carbon monoxide.

2. A reaction effluent according to claim 1 further comprising long chain alcohol having an α>0.74, wherein the reaction effluent is formed by a process for conversion of carbon monoxide and molecular hydrogen, the process comprising reaction conditions comprising i) conversion of 45 wt. % or more of carbon monoxide, and ii) a selectivity for formation of 1-alcohol of 40 wt. % or more relative to the weight of converted carbon monoxide.

3. The reaction effluent of claim 2 , wherein the long chain alcohol has an α≥0.8.

4. The reaction effluent of claim 1 , wherein the reaction conditions comprise a selectivity for formation of C 6 + 1-alcohol of 50 wt. % or more relative to the weight of 1-alcohol in the reaction effluent.

5. The reaction effluent of claim 1 , wherein the reaction conditions comprise a selectivity for formation of CO 2 of 25 wt. % or less relative to the weight of converted carbon monoxide.

6. The reaction effluent of claim 2 , wherein the reaction conditions comprise a selectivity for formation of C 6 + 1-alcohol of 50 wt. % or more relative to the weight of 1-alcohol in the reaction effluent.

7. The reaction effluent of claim 2 , wherein the reaction conditions comprise a selectivity for formation of CO 2 of 25 wt. % or less relative to the weight of converted carbon monoxide.

8. The reaction effluent of claim 1 , wherein the feed mixture comprises 10 wt. % or more of CO.
