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.
An iron-based ionic liquid catalyst composed of 5-20 wt. % iron and promoted with 0.05-2.0 wt. % of at least one active promotor metal including cobalt, molybdenum, palladium, platinum, nickel or tungsten or combination thereof with the remainder being water, the catalyst having a pH in the range of 0.1-3.0.
An iron-based ionic liquid catalyst composed of 5-20 wt % iron and promoted with addition of 0.05-2.0 wt. % molybdenum and 0.2-2.0 wt. % phosphoric acid with the remainder being water, the pH being from about 0.1 to 0.5.
A method for making an iron-based ionic liquid form catalyst in an aqueous solution containing iron and a promotor metal, the method comprising dissolving an iron salt and a promotor metal salt to provide an aqueous solution, said solution containing 5-20 wt % iron and 0.05-2.0 wt % of said promotor metal and having a pH at least 0.1.
A method for making an iron-based ionic liquid catalyst in an aqueous solution containing iron and a promoter metal salt, the method comprising the steps of dissolving an iron salt ferric sulfate pentahydrate and promotor salt ammonium heptamolybdate to provide an aqueous solution, said solution containing 5-20 wt % iron and 0.05-2.0 wt % of said metal promotor and having a pH of 0.1 to 0.5.
