Methods are provided for producing hydrocarbons. A method for producing hydrocarbons may include a method of removing impurities from a hydrocarbon stream using a strong base resin. The strong base resin absorbs at least a portion of the impurities from the hydrocarbon stream to provide a purified hydrocarbon stream. Further, the method for producing hydrocarbons may include feeding the purified hydrocarbon stream to a reaction zone comprising a catalyst to form a reaction zone effluent stream.

A catalyst system comprising a combination of: 1) one or more catalyst compounds having at least one nitrogen linkage and at least one oxygen linkage to a transition metal; 2) a support comprising an organosilica material, which is a mesoporous organosilica material; and 3) an optional activator. Useful catalysts include ONNO-type transition metal catalysts, ONYO-Type transition metal catalysts, and/or oxadiazole transition metal catalysts. The organosilica material is a polymer of at least one monomer of Formula [z0Z2 SiCH2]3(1), where Z.sup.1 represents a hydrogen atom, a C.sub.1-C.sub.4alkyl group, or a bond to a silicon atom of another monomer and Z.sup.2 represents a hydroxyl group, a C.sub.1-C.sub.4alkoxy group, a C.sub.1-C.sub.6alkyl group, or an oxygen atom bonded to a silicon atom of another monomer. This invention further relates to processes to polymerize olefins comprising contacting one or more olefins with the above catalyst system.

A metal loaded catalyst comprises a support and main active metal components and optional auxiliary active metal components, wherein the main active metal components are elementary substances and obtained by ionizing radiation reducing precursors of main active metal components. The catalyst can be widely used in the catalytic reactions of petrochemistry industry with high activity and selectivity. The catalyst can be used directly without being reduced preliminarily by hydrogen.

A hydroprocessing system involves introducing heavy oil and in situ formed metal sulfide catalyst particles, or a catalyst precursor capable of forming metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The metal sulfide catalyst particles are formed in situ by 1) premixing a catalyst precursor with a hydrocarbon diluent to form a precursor mixture, 2) mixing the precursor mixture with heavy oil to form a conditioned feedstock, and 3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil to form the metal sulfide catalyst particles in situ in the heavy oil. The in situ formed metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.

A system and method for preparing and conditioning a heavy oil feedstock for hydroprocessing in a hydroprocessing system includes forming metal sulfide catalyst particles in situ within the heavy oil feedstock. The metal sulfide catalyst particles are formed in situ by (1) premixing a catalyst precursor with a hydrocarbon diluent to form a diluted precursor mixture, (2) mixing the diluted precursor mixture with the heavy oil feedstock to form a conditioned feedstock, and (3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil feedstock to form metal sulfide catalyst particles in situ in the heavy oil feedstock.
