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.

Resid hydroprocessing method

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.

Resid hydroprocessing catalyst

An improved, low severity coal liquefaction process is disclosed. In accordance with the process, coal is first decarboxylated and demineralized with hot sulfurous acid. The decarboxylated coal is then liquefied in the presence of an alcohol and an alkali metal hydroxide. In several embodiments, alkali metal-containing materials are reclaimed to produce alkali metal hydroxide for the liquefaction step. In other embodiments, the liquefaction is conducted in the presence of a relatively high-boiling diluent such as a coal-derived liquid.

Integrated low severity alcohol-base coal liquefaction process

A coal liquefaction process employing a first stage liquefaction step catalyzed by a soluble molybdenum-containing organophosphorodithioate catalyst is disclosed. In some embodiments, two consecutive liquefaction steps employ a molybdenum-containing organophosphorodithioate catalyst operating at a relatively high liquefaction temperature. In other embodiments, a second liquefaction process step operating at a relatively low temperature employs a hydrocracking catalyst to upgrade materials obtained from the first soluble catalyst liquefaction step. In some embodiments, an interstage gas separator removes gases such as carbon dioxide produced in the first liquefaction step from a partially liquefied mixture prior to further liquefying the mixture in the second liquefaction step.

Coal liquefaction process using soluble molybdenum-containing

A composition consisting essentially of a carbonaceous solid containing at least one carboxyl group is heated with subcritical liquid water at decarboxylation conditions including a temperature of at least about 300.degree. F. to substantially decarboxylate the solid, thereby producing a stream comprising a decarboxylated solid and water. The water is separated from the decarboxylated solid prior to liquefying the solid.
