There is provided a process for the direct partial oxidation of methane with oxygen, whereby hydrocarbons having at least two carbon atoms are produced. The catalyst used in this reaction is a spinel oxide such as ZnMn.sub.2 O.sub.4.

The invention relates to a method for converting methane into higher hydrocarbons. According to the invention, a catalyst comprised essentially of a metal belonging to the series of transition metals and of a carrier which is comprised particularly of a refractory metal oxide is subjected to a methane flow at a temperature comprised between 100.degree. C. and 300.degree. C. approximately, with a contact time of at least one second, and to a hydrogen flow at a temperature comprised between 100.de...

Light olefins are converted to heavier hydrocarbon products, e.g., those boiling in the gasoline, distillate, and/or lube range, under oligomerization reaction conditions in the presence of catalyst comprising zeolite MCM-49.

The thermal properties, such as heat distortion temperature of biodegradable polymers, such as polylactic acid, polyglycolides, polybutyric acid and copolymers of butyric and valeric acid, may be increased by blending them with a polymer having Tg from 75.degree. C. to 200.degree. C. and a Hildebrand parameter (.sigma.) of not more than 3 MPA.sup.1/2 different from the biopolymer.

Alkyl (C.sub.4 -C.sub.12), cycloalkyl (C.sub.3 -C.sub.8), and unsaturated hydrocarbyl (C.sub.3 -C.sub.10) esters of 2-nitro-5-(halophenoxy)benzoic acids comprise a class of compounds that are highly effective pre- and post-emergence herbicides.

A method of increasing the performance of an FET device by aligning the channel of the FET with the [110] crystal direction of a {100} silicon wafer. The {100} silicon wafer and the image of a lithographic mask are rotated 45 cc.degree. relative to each other so that, instead of the channel being aligned parallel with the [100] crystal direction in the conventional fabrication, the channel is aligned approximately parallel with the [110] crystal direction. The mobility of the carriers is higher ...

An amorphous polypropylene having a high weight average molecular weight prepared by a process in the presence of a catalyst comprising titanium-containing monocyclopentadienyl metallocene and aluminoxane.

This patent is concerned with a unique process for converting natural gas into hydrocarbons. More particularly, it concerns a novel combination of processing steps wherein the natural gas is first converted into syn gas, the hydrogen of which is reacted with carbon dioxide to produce a mixture of water and carbon monoxide which is then contacted with a metal catalyst to give a mixture of hydrocarbons.

Highly dispersed oxides of metals and/or silicon are hydrophobized by treatment with volatilizable organosilicon compounds in the gas phase. The oxide particles either come fresh from the production plant or are previously absolutely dried, and activated i.e., freed of physically and chemically bound water, in a fluidized bed with a dry inert gas stream at a temperature of 550.degree. to 1000.degree.C., preferably 600.degree. to 950.degree.C. under normal pressure in a few seconds to a few minut...
