摘要:
Linear alpha olefins having from four to twenty carbon atoms and low amounts of oxygenates are synthesized, by producing a synthesis gas containing H2 and CO from natural gas and passing it over a non-shifting cobalt catalyst at reaction conditions of temperature, % CO conversion, and gas feed H2:CO mole ratio land water vapor pressure, effective for the mathematical expression 200−0.6T+0.03PH2O−0.6XCO−8(H2:CO) to have a numerical value greater than or equal to 50. This process can be integrated into a conventional Fischer-Tropsch hydrocarbon synthesis process producing fuels and lubricant oils.

A synthetic, isoparaffinic heavy hydrocarbon composition useful as a heavy lubricant base stock contains hydrocarbon molecules having consecutive numbers of carbon atoms, is a liquid at 100° C., at which temperature its kinematic viscosity is above 8 cSt and has respective initial and end boiling points of at least 850 and 1000° F. (454 and 538° C.). The branching index BI and the branching proximity CH2>4 of the isoparaffinic hydrocarbon molecules, are such that: BI−0.5(CH2>4) 4)

A heavy hydrocarbon composition with utility as a heavy hydrocarbon base stock comprising at least 95 wt % paraffin molecules, of which at least 90 wt % are isoparaffin, containing hydrocarbon molecules having consecutive numbers of carbon atoms, is a liquid at 100° C., at which temperature its kinematic viscosity, as measured by ASTM D-445, is above 8 cSt, has an initial boiling point of least 850° F. (454° C.) and an end boiling point of at least 1000° F. (538° C.), wherein the branching index (BI), as measured by the percentage of methyl hydrogens, and the branching proximity (CH2>4), as measured by the percentage of recurring methylene carbons which are four or more carbon atoms removed from an end group or branch, of said isoparaffinic hydrocarbon molecules, are such that: (a) BI−0.5(CH2>4) 4)
摘要:
A novel catalyst and process for the manufacture of polyhydric alcohols from synthesis gas. This novel catalyst is a rhodium carbonyl sulfur cluster compound. In particular, the anion cluster of the rhodium carbonyl sulfur compound is of the following empirical formula:[Rh.sub.17 (S).sub.2 (CO).sub.32 ].sup.-3
