Abstract
Hydroconversion processes employing 2,4-heteroatom-substituted-molybdena-3,3-dioxocyclopentane hydro-conversion catalysts are disclosed. In some embodiments, inexpensive bulk catalysts in accordance with the present invention are synthesized from bulk triglyceridic epoxides or fatty acids.
Claims22
A hydrotreating process for converting a hydrocarbonaceous feedstock to lighter products comprising hydrotreating a reaction mixture containing the feedstock and a feedstock-soluble catalyst under hydrotreating conditions, said catalyst comprising the composition:
- ##STR7## where X.sub.1 and X.sub.2 are selected from the group consisting of O, S or NH, and wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently selected from the group consisting of hydrogen or an alkyl, aryl or alkyl/aryl hydrocarbon group containing from 1 to 40 carbon atoms or heteroatom-substituted variants thereof in which one or more hydrogen atoms have been substituted for by one or more oxygen-, sulfur- or nitrogen-containing functional groups.
A hydrotreating process for coverting a hydrocarbonaceous feedback to lighter products comprising hydrotreating a reaction mixture containing the feedback and a feedstock-soluble catalyst under hydrotreating conditions, said catalyst comprising a 2,4-heteroatom substituted-molybdena-3,3-dioxacylopentane-containing, triglyceride-derived compound prepared by the process of:
- (a) epoxidizing triglycerides to form a mixture in which epoxide groups have been introduced into fatty acid chains of the triglyceride;
- (b) reacting expoxidized fatty acid chains from step (a) into diol or thiol-alcohol groups;
- and
- (c) reacting diol or thiol-alcohol containing-chains from step (b) with molybdenum to produce chains containing a 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane ring structures.
A hydrotreating process for converting a hydrocarbonaceous feedback to lighter products comprising hydrotreating a reaction mixture containing the feedstock and an feedstock-soluble catalyst under hydrotreating conditions, said catalyst comprising a 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane-containing, fatty acid derived compound prepared by the process of:
- (a) epoxidizing fatty acid chains to introduce epoxide groups into the chains;
- (b) converting epoxidized fatty acid chains from step (a) into diol or thiol-alcohol containing chains;
- and
- (c) reacting the diol or thiol-alcohol containing-chains with molybdenum to produce chains containing 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane ring structures.
A hydrotreating process for converting a resid feedstock to lighter products comprising hydrotreating a reaction mixture containing the feedstock and between about 20 and 1000 parts per million of a feedstock molybdenum metal under hydrotreating conditions, said catalyst selected from the group consisting of;
- (i) 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane-containing, fatty acid-derived compounds prepared by the process of:
- (a) epoxidizing fatty acid chains to introduce epoxide groups into the chains;
- (b) converting epoxidized fatty acid chains from step (a) into diol or thiol-alcohol containing chains;
- and
- (c) reacting the diol or thiol-alcohol containing-chains with
- molybdenum to produce chains containing 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane ring structures;
- (ii) 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane-containing, triglyceride-derived compound prepared by the process of:
- (a) epoxidizing triglycerides to form a mixture in which epoxide groups have been introduced into fatty acid chains of the triglyceride;
- (b) reacting epoxidized fatty acid chains from step (a) into diol or thiol-alcohol groups;
- and
- (c) reacting diol or thiol-alcohol containing-chains from step (b) with molybdenum to produce chains containing 2,4-heteroatom substituted-molybdena-3,3-dioxacyclopentane ring structures;
- and
- a composition have the structure:
- ##STR8## where X.sub.1 and X.sub.2 are selected from the group consisting of O, S or NH and wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently selected from the group consisting of hydrogen or an alkyl, aryl or alkyl/aryl hydrocarbon group containing from 1 to 40 carbon atoms or variants thereof in which one or more hydrogen atoms have been substituted for by one or more oxygen-, sulfur- or nitrogen-containing functional groups.
