Abstract: A catalyst, and method of preparing and using a catalyst, for the hydrodesulfurization of metal-containing heavy feedstocks, which has improved catalytic life and metals capacity. The catalyst contains Group VIB and Group VIII metals or metal compounds on a support comprising alumina wherein the support has 70 volume percent of its pore volume in pores having a diameter of between 140 and 220 .ANG..

Abstract: A catalyst, and method of preparing and using a catalyst, for the hydrodesulfurization of metal-containing heavy feedstocks, which has improved catalytic life and metals capacity. The catalyst contains Group VIB and Group VIII metals or metal compounds on a support comprising alumina wherein the support has at least 80 percent of said pore volume in pores having a diameter of between 110 and 190 .ANG. and at least 70 percent of said pore volume in pores having a diameter between 130 and 200 .ANG..

Abstract: A dimerization process for producing linear and/or mono-branched C.sub.10 to C.sub.28 olefins using dimerization catalysts and new C.sub.10 to C.sub.28 olefins mixtures are disclosed. The C.sub.10 to C.sub.28 olefin product is especially useful for the production of biodegradable alkylbenzene sulfonates detergents and intermediates therefor.

Abstract: A two-step dimerization process for producing semi-linear C.sub.12 olefins using homogeneous dimerization catalysts and new C.sub.12 olefins mixtures. The C.sub.12 product is especially useful for the production of biodegradable sulfonated alkylaryl detergents and intermediates therefor.

Abstract: A polymerization catalyst comprising a complex of nickel or palladium and certain fluoro-organo sulfur ligands and an organometal reducing agent. The catalyst is especially useful for the oligomerization of olefins to higher molecular weight olefins having a high degree of linearity.

Abstract: A process for oligomerization of a lower olefin having 2 to 8 carbon atoms which comprises contacting said lower olefin with a catalyst composition comprising a transition metal complex selected from complexes of nickel and palladium with a fluoro-organic thiol or sulfide ligand, having a single sulfur atom in a ligating position and wherein the carbon atom adjacent the carbon to which the sulfur atom is attached has at least one fluoro substituent and with the proviso that said fluoro-organic thiol or sulfide does not contain any other ligating group or atom in a ligating position which will displace fluoro as a ligand, and an organometallic-reducing agent selected from the group of borohydride and organoaluminum halides and alkoxides.

Abstract: A process for the preparation of methyl methoxyacetate by the oxycarbonylation of methanol which comprises reacting methanol with carbon monoxide in the presence of a hydrogen fluoride catalyst and an oxidizing agent containing a metal salt.
