A highly dispersed iron-based ionic liquid or liquid-gel catalyst which may be anion-modified and metals-promoted has high catalytic activity, and is useful for hydrocracking/hydrogenation reactions for carbonaceous feed materials. The catalyst is produced by aqueous precipitation from saturated iron salt solutions such as ferric sulfate and ferric alum, and may be modified during preparation with anionic sulfate (SO. sub. 4. sup. 2-) and promoted with small percentages of at least one active metal such as cobalt, molybdenum, palladium, platinum, nickel, or tungsten or mixtures thereof. The resulting catalyst may be used in a preferred ionic liquid form or in a liquid-gel form, and either fluidic form can be easily mixed and reacted with carbonaceous feed materials such as coal, heavy petroleum fractions, mixed plastic waste, or mixtures thereof. The invention includes methods for making the ionic liquid or liquid-gel catalyst, and processes for using the fluidic catalysts for hydroprocessing the carbonaceous feed materials to produce desirable low-boiling hydrocarbon liquid products.

A dispersed fine-sized anion-modified and phosphorus-promoted iron-oxide slurry catalyst having high surface area exceeding 100 m. sup. 2 /gm and high catalytic activity, and which is useful for hydrogenation and hydroconversion reactions for carbonaceous feed materials is disclosed. The catalyst is synthesized by rapid aqueous precipitation from saturated salt solutions such as ferric sulfate and ferric alum, and is promoted with phosphorus. The iron-based catalysts are modified during their preparation with anionic sulfate (SO. sub. 4. sup. 2-). The resulting catalyst has primary particle size smaller than about 50 Angstrom units, and may be used in a preferred wet cake or gel form which can be easily mixed with a carbonaceous feed material such as coal, heavy petroleum fractions, mixed waste plastics, or mixtures thereof.

This invention provides a continuous process for separating a gaseous phase from a hydrocarbon liquid containing carbonaceous particulates and gases. The liquid is fed to a cylindrical separator, with the gaseous phase being removed therefrom as an overhead product, whereas the hydrocarbon liquid and the particulates are withdrawn as a bottoms product.

A process for the hydrogenation of undissolved coal and subsequent liquefaction of the hydrogenated coal particles to provide useful hydrocarbon liquid products including naphtha, gasoline and diesel fuel. These low boiling hydrocarbon liquids are produced by the process comprising: (a) mixing solid coal particles with a coal derived solvent in a solvent/coal ratio ranging from about 8/1 to about 1. 5/1 to provide a flowable coal/oil slurry of solid coal particles; (b) passing the coal/oil slurry and hydrogen upwardly through a first reaction zone containing a coal-derived liquid and bed of particulate catalyst maintained at a temperature ranging from about 400. degree. to about 700. degree. F. and a hydrogen partial pressure of 100 to 2000 psig for a time sufficient to hydrogenate the solid coal particles; and (c) withdrawing the coal/oil slurry having the hydrogenated coal particles from the first reaction zone and passing the coal/oil slurry to a second reaction zone containing a catalytic bed which is maintained at a temperature of between about 700. degree. and about 850. degree.

A multi-stage catalytic hydrogenation and hydroconversion process for heavy hydrocarbon feed materials such as coal, heavy petroleum fractions, and plastic waste materials. In the process, the feedstock is reacted in a first-stage, back-mixed catalytic reactor with a highly dispersed iron-based catalyst having a powder, gel or liquid form. The reactor effluent is pressure-reduced, vapors and light distillate fractions are removed overhead, and the heavier liquid fraction is fed to a second stage back-mixed catalytic reactor. The first and second stage catalytic reactors are operated at 700-850. degree. F. temperature, 1000-3500 psig hydrogen partial pressure and 20-80 lb. /hr per ft. sup. 3 reactor space velocity. The vapor and light distillates liquid fractions removed from both the first and second stage reactor effluent streams are combined and passed to an in-line, fixed-bed catalytic hydrotreater for heteroatom removal and for producing high quality naphtha and mid-distillate or a full-range distillate product.

This invention discloses a staged process for drying wet carbonaceous materials such as sub-bituminous coal or lignite containing at least about 10 weight percent moisture, usually 15-50 weight percent moisture, by first heating the wet material under low partial pressure of moisture to permit the controlled rapid escape of surface moisture down to a critical moisture content of 8-12 weight percent. In a second step, the material is further heated at lower differential vapor pressure to provide for further moisture evolution at a slower controlled rate. This staged drying procedure permits wicking up of hydrocarbons contained in the coal to seal the surface of the dried coal product sufficient to prevent appreciable reabsorption of moisture and consequent heating and spontaneous ignition.
