Title: Novel Fischer-Tropsch catalysts

Patent ·
OSTI ID:6038303

A procedure is claimed for preparing novel polymer-supported metal complexes of the formula ps-r me(Co)nhm where: ps represents a divinylbenzene crosslinked polystyrene in which the divinylbenzene crosslinking is greater than 1% and less than about 18%; r represents a cycloalkadienyl radical of 4 through 6 carbon atoms; me represents a group viii metal; co represents a carbonyl radical; h represents hydrogen; n represents an integer varying from 0 through 3; m represents an integer varying from 0 through 2 inclusively with the further provision that 2n+m must total 18 when added to the electrons in r and me, or n+m must total 0. These metal complexes are prepared by: brominating ps-h by treating same with bromine in the presence of a thallium salt in a partially or fully halogenated solvent to form ps-br; treating said ps-br so produced with a lithium alkyl of 1 through 12 carbon atoms in an aromatic solvent to produce ps-li; substituting said ps-li so produced by reaction with a 2cycloalkenone of 4 to 6 carbon atoms in the presence of an ether solvent and using a water work-up to form a cycloalkenyl alcohol-substituted ps; dehydrating said alcohol so produced by heating under a vacuum to produce a cycloalkadienyl-substituted ps; reacting the cycloalkadienyl-substituted ps with metal carbonyl in the presence of a partially or fully halogenated hydrocarbon, aromatic hydrocarbon of 6 through 8 carbon atoms, ethers, or esters of 4 through 10 carbon atoms as a solvent to produce a polystyrene-supported cycloalkadienyl metal carbonyl. The novel compounds are used as improved Fischer-Tropsch catalysts particularly for the conversion of CO+H/sub 2/ to gaseous and liquid hydrocarbons at milder conditions than with prior catalysts.
