Syngas is subjected to Fischer-Tropsch synthesis over a special Co/Zr/SiO₂ catalyst and the C₂₀⁺ fraction of the synthesized product is converted into linear C₁₀-C₂₀ olefins by mild thermal cracking.

Process for the isomerization of unbranched hydrocarbons

A process for the isomerization of unbranched hydrocarbons by separating a feed mixture containing different unbranched hydrocarbons (e.g. C5-C7 n-paraffins) into at least two fractions having different average molecular masses, introducing each fraction separately in order of increasing average molecular mass further downstream into a series of isomerization zones operated at isomerization conditions in the presence of hydrogen and an isomerization catalyst, and removing product from the furthest downstream zone.

Process for the production of methanol and catalyst composition for said process

A process for the production of methanol comprising contacting a gaseous mixture comprising of carbon monoxide and hydrogen with a catalytic system, obtainable by combination of: component (a): a substantially dry nickel formate, component (b): water in a predetermined amount in relation to the nickel formate amount and, component (c): an alcoholate derived from an alkali metal or from an alkaline earth metal, and a catalyst system to be used in this process. Preferably the molar ratio between nickel formate and water is in the range from 1:3.5 to 1:1 and more preferably from 1:3.0 to 1:1.5.

Dual catalyst fischer-tropsch preparation of hydrocarbons

Syngas with a H2/CO mol.ratio between 0.25 and 1.0 is converted into hydrocarbons by contacting it with a mixture of a special cobalt-containing Fischer-Tropsch catalyst and a Cu- and Zn-containing Co-shift catalyst. In this mixture the two catalysts are present in such amounts that the following relation is met: <MATH> M being the (Cu + Zn)/Co atomic ratio in the catalyst mixture and F being the H2/CO mol.ratio in the syngas.

Thermoplastic gel coat

ABTRACTThe present invention relates to a liquid, thermoplastic acrylic gel cap composition that can impart UV resistance, higher impact, and aesthetic effects to a composite material. Additionally, the post processing of the material when combined with a thermoplastic composite can allow for thermoformability, weldability and recyclability, unlike seen with traditional thermoset based gel coats.

Stabilizers for hydrolyzable organic binders

The present invention relates to triorgano phosphites, triorgano amines, heteroaromatic nitrogen compounds, and carbodiimides used as stabilizers for hydrolyzable organic binders. The stabilizers help to prevent viscosity thickening of polymeric binders containing carboxylic ester groups. Without stabilization, the binders can rapidly thicken when exposed to moisture air. The stabilized organic binders of the invention are especially useful for formulating marine antifoulant coatings.

Process for the hydrocracking of a hydrocarbonaceous feedstock

A B S T R A C T PROCESS FOR THE HYDROCRACKING OF A HYDROCARBONACEOUS FEEDSTOCK A hydrocarbonaceous feedstock is hydrocracked in a plurality of reaction stages by contacting the feedstock with a first hydrocracking catalyst at elevated temperature and pressure in the presence of hydrogen in a first reaction stage to yield a first effluent, mixing at least a liquid portion of the first effluent with a second effluent that originates from a second reaction stage, contacting the mixture obtained in a third reaction stage with a third hydrocracking catalyst at elevated temperature and pressure in the presence of hydrogen to yield a third effluent, passing the third effluent to a separation stage where at least one top fraction and a residual fraction are obtained and passing the residual fraction to the second reaction stage where it is contacted with a second hydrocracking catalyst at elevated temperature and pressure in the presence of hydrogen to yield the second effluent.
