A hydroconversion process for converting a heavy hydrocarbonaceous feedstock to lower boiling products, which process involves the use of a sulfided catalyst concentrate which is prepared in a continuous plug-flow mode. The heavy hydrocarbonaceous feedstock is reacted with said catalyst concentrate in the presence of hydrogen at hydroconversion conditions.

Hydroconversion process with plug-flow molybdenum catalyst concentrate

A method for converting solid carbonaceous materials to liquid products. The solid carbonaceous material is first treated with a aqueous composition of a metal carbonate or bicarbonate. This results in the metal being atomically dispersed in the carbonaceous material. The treated solid carbonaceous material is then subjected to liquefaction conditions. The preferred metal is iron.

Coal liquefaction using atomically dispersed metals

A process for the atomic dispersion of metals into support materials, preferably silica, alumina, and amorphous and zeolitic alumino-silicates. The support material is contacted with an aqueous composition of a metal carbonate, or bicarbonate. This results in the metal being atomically dispersed in the support material.
