The present invention provides for a process for converting a feedstock comprising ethylene and/or acetylene to a product comprising liquid hydrocarbons. The process comprises maintaining said feedstock at a temperature in the range of about 700.degree. C. to about 1000.degree. C. for about 100 to about 1000 milliseconds to provide for said conversion. In one embodiment, the feedstock further comprises hydrogen. In another embodiment the feedstock comprises the product made by the process comprising heating a gaseous mixture comprising (i) hydrogen and (ii) natural gas and/or at least one light hydrocarbon at a temperature of at least about 1250.degree. C. for an effective period of time to provide said feedstock. In still another embodiment, the feedstock further comprises natural gas and/or at least one light hydrocarbon in addition to said ethylene and/or acetylene.

A catalyst is disclosed which comprises a molybdenum-tungsten-containing complex represented by the formula

Molybdenum-tungsten-containing catalyst for methane conversion process

The invention relates to a process for converting light hydrocarbon feedstocks such as methane and/or natural gas, to higher molecular weight hydrocarbon products that are more readily handleable and transportable. The process comprises heating a gaseous mixture comprising said light hydrocarbon feedstocks and a minor, effective amount of at least one ether or thioether compound at a temperature of at least about 800.degree. C. for a period of time effective to provide said higher molecular weight liquid hydrocarbon product. The invention also relates to the higher molecular weight liquid products obtained by the process of the invention.

Molybdenum-tungsten-containing catalyst and methane conversion process

In a process for the production of hydrogen by the reaction of steam with carbon, a catalyst system is employed comprising a supported Group VIIIA metal and, as modifier for the suppression of methane, an effective amount of an oxide of molybdenum or tungsten.

Process for the production of hydrogen

An alcohol such as methanol is decomposed to form hydrogen and carbon monoxide at elevated temperature in the presence of mixed metal oxide catalyst containing copper and a metal L selected from the group consisting of Th, Be, Zr, Ce, Mg and U. The catalyst can contain a further metal M selected from the group consisting of Ca, Mo, Mn, Pt, Ce, Cr, Zn, Al, Ti, La, V, U, Ru, Re and Pd. The catalysts are particularly effective at relatively low temperatures for example 200.degree.-200.degree. C.

Fly ash is activated by heating a screened magnetic fraction of the ash in a steam atmosphere and then reducing, oxidizing and again reducing the hydrothermally treated fraction. The activated fly ash can be used as a carbon monoxide disproportionating catalyst useful in the production of hydrogen and methane.

Activation of fly ash

A process for producing HCN by contacting CO and NH.sub.3 with a catalyst comprising a porous catalyst support, a Group VIII metal which is at least one of Fe, Ni, Co and Ru, and carbon, wherein the metal is disposed on the pore surfaces of the support and the carbon is randomly bonded to the metal.

Aryl ethers, e.g., cumylmethylether and anisole, are particularly effective additives for improving the octane number of motor fuels. These aryl ethers are especially useful in increasing the octane number of unleaded gasolines.

Motor fuel additive

Cyclohexenyl and alkenyl aromatic compounds, such as cyclohexene and styrene, are prepared by a process comprising contacting a corresponding cyclohexyl or alkyl aromatic carboxylic acid, such as cyclohexyl carboxylic acid or 2-phenyl propionic acid, with a decarboxylation catalyst of the formula

Preparation of cyclohexenyl compounds

2-phenyl propanal is converted to 2-indanone by contact at conversion conditions, typically vapor-phase conditions, with a catalyst of the formula Mo.sub.12 Cu.sub.0.1-10 V.sub.0.1-5 W.sub.0.1-3 M.sub.0-3 O.sub.x where M is an optional promoter, such as Sn, Sb, Te or a Group VIII element.

Conversion of 2-phenyl propanal to 2-indanone

Mononuclear aromatic hydrocarbons, e.g. benzene and analogs, are converted by hydroalkylation to the corresponding cycloalkyl aromatics by contacting the mononuclear aromatic hydrocarbons in the presence of hydrogen with a catalyst comprising a rare earth-exchanged Y-type zeolite support carrying a promoter comprising at least one of ruthenium, iridium, rhodium and palladium, the catalyst being calcined in an oxygen-containing atmosphere at a temperature of 250.degree. to 600.degree. C. prior to the hydroalkylation reaction.

Hydroalkylation of benzene and analogs

A fixed-bed catalytic material comprises iron impregnated Alundum carrying a coating of copper oxide on its outside surfaces. By means of the coating, the growth of carbon fibers as a result of the disproportionation of carbon monoxide is restricted to the interior surfaces of the catalyst particles.
