Abstract: A process for preparation of a paraffin isomerization catalyst comprising a mixture of a Group IVB metal oxide, a Group VIB metal oxide, a Group IIIA metal oxide and a Group VIII metal. The process includes the steps of: a) contacting a hydroxide of the Group IVB metal with an aqueous solution of an oxyanion of the Group VIB metal to provide a mixture, (b) drying the mixture to provide a dry powder, (c) kneading the powder with a Group IIIA hydroxide gel and a polymeric cellulose ether compound to form a paste, (d) shaping the paste to form a shaped material, (e) calcining the shaped material to form a calcined material, (f) impregnating the calcined material with an aqueous solution of a Group VIII metal salt to provide the catalyst, and (g) calcining the catalyst.

Abstract: A process for hydrocracking a hydrocarbon feedstock comprising components boiling above 343° C. into a middle distillate fraction in the presence of hydrogen under hydrocracking conditions, comprising contacting the hydrocarbon feedstock in a first hydrocracking zone in the presence of one or more hydrocracking catalysts and thereafter in a second hydrocracking zone in the presence of one or more hydrocracking catalysts, and recovering a middle distillate product, wherein the entire effluent from the first hydrocracking zone is passed into the second hydrocracking zone, and at least one hydrocracking catalyst in the first hydrocracking zone comprises one or more hydrogenation components on a support comprising at least one large pore zeolite having a pore diameter in the range of 0.7-1.

Abstract: A process for hydrocracking a hydrocarbonaceous feedstock into a middle distillate utilising a hydrocarbon conversion catalyst comprising a modified beta zeolite and a modified Y zeolite, an amorphous inorganic oxide and a hydrogenation component, wherein the said middle distillate is characterised by having a low aromatics content and/or a low pour point.

Abstract: A process for the preparation of an isomerisation catalyst comprising mixed aluminium, tungsten and zirconium oxides and a hydrogenation/dehydrogenation component, such as palladium or other Group VIII metals. The catalyst is useful in an isomerisation process for C4+ paraffins and may optionally also include shorter paraffins, aromatics or cycloparaffins.

Abstract: Process for the removal of higher hydrocarbons contained in natural gas further containing sulphur compounds by simultaneous conversion of the hydrocarbons to aromatic compounds and methane in presence of a catalyst comprising a crystalline alumino silicate having in its anhydrous state a formula expressed in terms of mole ratios as follows: xQ:0.01–0.1 M2/nO:0–0.08 Z2O3:SiO2:0.0001–0.5 Me, wherein: Q is an organic nitrogen compound; Z is aluminum, boron, gallium or mixtures thereof; x is between 0 and 0.5; M is at least one metal cation of valence n or proton; and Me is at least one of the metals, which form a water insoluble sulphide by contact with a sulphur compound being present in the natural gas and/or in a preparation mixture for preparation of the catalyst.

Abstract: Method for the depression of soot formation during combustion of fuel rich hydrocarbons in a combustion chamber by applying an electrostatic field in the combustion chamber by means of one or more electrodes at least a portion of the electrodes extend into the chamber, wherein the portion of the electrodes extending into the chamber comprises porous ceramic material.

Abstract: Method of operating a compression engine on dimethylether containing fuel obtained by conversion of methanol primary fuel, comprising the steps of: (a) pressurising the primary methanol fuel in its liquid form to a final engine injection pressure; (b) preheating the pressurised primary fuel by heat contained in engine exhaust gas; (c) introducing and converting the primary fuel at injection temperature of the engine and the injection pressure to dimethylether containing fuel by contact with a methanol dehydration catalyst; and (d) injection the dimethylether containing fuel at the injection pressure and temperature into the engine.

Abstract: Process for the dehydrogenation of a hydrocarbon feed comprising a step of dehydrogenating the hydrocarbon feed and a step of removing hydrogen being formed by dehydrogenation reactions, wherein the dehydrogenation and hydrogen removal steps are performed simultaneously in presence of a dehydrogenation catalyst being combined with a metal compound being reduced in presence of hydrogen.
