摘要:
A phosphomolybdic acid catalyst is made by mixing an aqueous solution of phosphomolybdic acid with a hydrocarbonaceous oil, drying the mixture and contacting the dried mixture with H₂S to sulfide the dried mixture and then heating the sulfided mixture to convert same to a solid molybdenum-containing catalyst-containing material. The said material is useful for hydrocarbon hydroconversion processes.

摘要:
Disclosed is a process for converting heavy hydrocarbonaceous feedstock to more valuable products. The feedstock is introduced into a coking unit (14) containing a coking zone (12) and a scrubbing zone (24). The bottoms fraction (28) from the scrubbing zone is passed through a microfiltration unit (30), thus removing fine coke particles which are recycled (32) to the coking zone (12). The substantially solids-free filtrate (36) is hydrotreated (48), then passed to a catalytic cracking unit (52).
摘要:
A slurry catalytic hydroconversion process comprising at least two hydroconversion zones is provided in which heavy hydrocarbonaceous fresh oil feed is added to more than one hydroconversion zone. Catalysts or catalyst precursors are added to the first hydroconversion zone and preferably also to subsequent hydroconversion zone(s) wherein said subsequent hydroconversion zone(s) are maintained at a temperature of at least 10°F (5.55°C) higher than an immediately preceding hydroconversion zone.
摘要:
A process for converting a heavy hydrocarbonaceous chargestock to lower boiling products, at hydroconversion conditions and in the presence of hydrogen, wherein a presulfided catalyst precursor concentrate is introduced with the chargestock into a hydroconversion zone. The hydroconversion is conducted at a temperature from about 425°C to 510°C and a hydrogen partial (gauge) pressure of from about 50 to 5,000 psig (0.345 to 34.475 MPa).
摘要:
A slurry hydroconversion process is provided in which a catalyst precursor concentrate comprising an aqueous solution of phosphomolybdic acid and a heavy oil is contacted with hot hydrogen to vaporize the water from the concentrate. The resulting catalyst precursor concentrate is introduced into a hydrocarbonaceous chargestock and the resulting mixture is heated in the presence of added hydrogen to convert the phosphomolybdic acid to a solid molybdenum-containing catalyst. The resulting slurry is subjected to hydroconversion conditions. The solid molybdenum-containing catalyst of the resulting hydroconverted products is separated and may be introduced into fresh hydrocarbonaceous chargestock.
