Abstract: A catalyst component is a transition metal composition which is obtained by reacting together an inert particulate material, an organic magnesium compound, a halogen-containing compound such as carbon tetrachloride or silicon tetrachloride and a specified transition metal compound. The catalyst component obtained can be used, together with an organic metal compound, to give an olefin polymerization catalyst. The catalyst can be used to effect the polymerization of olefin monomers, for example, the copolymerization of ethylene with an alpha-olefin monomer such as butene-1 in a fluidized bed reactor.

Abstract: A titanium containing composition is obtained by contacting a magnesium halide with a non-metallic halide such as thionyl chloride, for example by grinding, and contacting the product with a titanium tetrachloride-containing material, preferably undiluted liquid titanium tetrachloride. The treatment with titanium tetrachloride may be effected by milling or by suspending the solid in the titanium tetrachloride. The solid product can be washed at least once. An ester is preferably contacted with the magnesium halide. The product obtained may be used with an organic metal compound such as aluminum triethyl and preferably a Lewis Base such as ethyl benzoate or an organic silicon compound to give olefin polymerization catalyst. When used to polymerise propylene the product obtained is highly stereoregular and the level of residual catalyst is low.

Abstract: A supported transition metal composition is obtained by suspending a support material in an inert liquid medium, spraying the suspension, collecting a solid material and contacting the sprayed solid with a transition metal compound.

In addition to being contacted with the transition metal compound, the support material may be contacted either before or after the spraying step with other reagents such as organo metallic compounds, halogen compounds, or Lewis Base compounds. The product obtained after contacting with the transition metal compound may be used as a component of a polymerization catalyst system to polymerize an unsaturated monomer such as ethylene or propylene.

Abstract: Catalysts for the polymerization of ethylene or its copolymerization with C.sub.3 -C.sub.2 alpha-monoolefins are often pre-activated by polymerizing a small amount of C.sub.4 -C.sub.12 alpha-monoolefin onto the catalyst in the presence of an alkyl aluminum compound. The resultant pre-activated catalyst component is used in the form of a dispersion in an inert solvent. The dispersions have a tendency to separate into two phases rapidly and are thus difficult to add uniformly to a polymerization reaction. When the alkyl aluminum compound is replaced by a synergistic mixture of an alkyl aluminum choride and an oxygen-containing aluminum compound having oxygen attached to at least one aluminum valence, a stable dispersion is formed which will not separate into two phases for long periods of time.

Abstract: A two-stage catalytic hydroconversion process for heavy hydrocarbon feedstocks usually containing fine particulate solids to produce lower boiling hydrocarbon liquid and gas products. The feedstock is fed into a first stage ebullated bed reactor containing fine sized catalyst and operated at moderate reaction conditions for hydroconversion to produce hydrocarbon gas and liquid fractions, from which a low boiling liquid fraction is separated and withdrawn as a product. The remaining gas and heavier liquid fractions are recombined and fed to a second stage ebullated bed reactor containing larger size catalyst for further hydroconversion reactions at less severe conditions to produce lower boiling hydrocarbon liquid fractions. Following product distillation steps, liquid product fractions are withdrawn and a portion of vacuum bottoms material is recycled to the second stage reactor to provide increased hydroconversion and improved yields of the light hydrocarbon liquid product.
