A catalyst and a process for using the catalyst are presented. The catalyst is a heterogeneous catalyst and includes active metal halides bonded to functional groups. The functional groups are bonded to a polymeric backbone to form the structure supporting the catalyst. The catalyst is useful for the dimerization of acetylene to convert the acetylene to a larger hydrocarbon, and in particular to dimerize acetylene to vinylacetylene.

The invention relates to a method of producing carbonyl compounds, more particularly C-Cketones and aldehydes. The method is based on the gas-phase oxidation by nitrous oxide of C-Calkane-olefin mixtures, such as a butane-butylene fraction or a propane-propylene fraction, obtained by thermal and/or catalytic cracking, to produce C-Cketones and aldehydes. The process is carried out under continuous flow conditions at a temperature of 300-550&#xb0; C. and pressure of 1-100 atm, without prior isolation of individual olefins from the fractionation products and in the absence of a catalyst. The process provides for high productivity, high overall selectivity for ketones and aldehydes, and explosion-safe operation.

The present invention relates to a process for the hydrotreatment of a vegetal biomass. Specifically, the present invention relates to a process for the hydrotreatment of a vegetal biomass comprising: a) subjecting said vegetal biomass to a hydrotreatment in a first reactor, said hydrotreatment comprises contacting said vegetal biomass in an aqueous medium and a metal oxide, a mixed metal oxide, or a metal-metalloid oxide catalyst comprising at least 35% by weight of metal oxide, mixed metal oxide, or metal-metalloid oxide relative to the total weight of the catalyst, with hydrogen at a pressure in the range of 10 to 400 bar and at a temperature in the range of 50&#xb0; C. to 300&#xb0; C. until a predetermined level of the hydrotreatment of said biomass is obtained and wherein the metal oxide, a mixed metal oxide, or a metal-metalloid oxide catalyst comprises nickel. Further, the present invention relates to a metal oxide, mixed metal oxide or metal-metalloid oxide catalyst. Furthermore, the present invention relates to the use of the catalyst.

Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuZnAlOin a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOand low sulfur hydrocarbons. The by-product SOis subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.

Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuZnAlOin a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOand low sulfur hydrocarbons. The by-product SOis subsequently removed, producing a stream containing a reduced level of organosulfur compounds.

The inventive method for hydrogen sulphide and/or mercaptans decomposition consists in passing hydrogen sulphide and/or mercaptan-containing gas at a temperature less than 200&#xb0; C. through a hard material layer (catalyst) which decomposes said hydrogen sulphide or mercaptans in such a way that hydrogen or hydrocarbons are released and sulphur-containing compounds are formed on a material surface. Said hard material is placed in a liquid medium layer. Said invention makes it possible to use a hard material (catalyst) without a periodical regeneration thereof.

The invention discloses a method for selectively introducing carbonyl groups into polymers by oxygenation of double C&#x2550;C bonds of polymers with the aid of nitrous oxide (NO) at a temperature comprised between 50 and 350&#xb0; C. and a pressure of NO of from 0.01 to 100 atmospheres. The introduction of an insignificant amount of C&#x2550;O groups allows one to modify the physico-chemical properties of a polymer, with its molecular weight and molecular-weight distribution preserved. Deeper oxygenation results in controlled cleavage of polymer macromolecules and makes it possible to produce oxygen-containing oligomers having a desired molecular weight.
