In a process for the oxidation of a lower alkene, such as ethylene, over a catalyst containing Cu and one or more zeolite or zeotype materials, the oxidation is conducted in the presence of ammonia in the feed gas at a process temperature below 350&#xb0; C. The oxidation can be performed in a continuous process.

Process for oxidation of a lower alkene at low temperatures in ammonia-containing gas mixtures

In a process for the oxidation of a lower alkane, such as methane, over a catalyst containing Cu and one or more zeolite or zeotype materials, the oxidation is conducted in the presence of ammonia in the feed gas at a process temperature below 350&#xb0; C. The oxidation can be performed in a continuous process.

A catalyst material comprising 10-ring zeolite crystallites with one-dimensional non-intersecting channels wherein, the crystallites have an average length of less than 150 nm. The catalysts are useful in a method for producing hydrocarbons by reaction of oxygenates over said catalysts.

Catalyst comprising small 10-ring zeolite crystallites and a method for producing hydrocarbons by reaction of oxygenates over said catalyst

A catalyst for the conversion of oxygenates, such as alcohols or ethers, to olefins consists essentially of a selected SUZ-4 zeolite that has a Si/Al ratio of at least 20, preferably between 20 and 500, especially between 20 and 100. The basic SUZ-4 zeolite is prepared in a manner known per se, whereafter the Si/Al ratio is increased to the desired value. The selected SUZ-4 zeolite catalyst of the invention has a longer life time and a better product selectivity than the conventional/standard SUZ-4 zeolite catalysts.

Method of removing metal carbonyls from a gaseous stream comprising contacting the metal carbonyl containing gaseous stream at elevated temperature with a particulate sorbent comprising modified copper aluminum spinel, wherein the copper aluminium spinel has been modified by a thermal treatment in a reducing atmosphere and a particulate sorbent for use in a method comprising a copper aluminium spinel being modified by thermal treatment in a reducing atmosphere at a temperature of between 250 and 500&#xb0; C.

Method of removing metal carbonyls from gaseous streams and metal carbonyl sorbent

Process for the preparation of ethanol and/or higher alcohols comprising the steps of: (a) providing an alcohol synthesis gas comprising carbon monoxide and hydrogen in a molar ratio of higher than 0.5; (c) adding an amount of methanol and/or higher alcohols to the synthesis gas to obtain a synthesis gas mixture. (d) converting the synthesis gas mixture from step (c) in presence of one or more catalysts catalysing the conversion of the synthesis gas mixture into a ethanol and/or higher alcohols containing product; and (e) withdrawing the product from step (d), wherein the synthesis gas is purified by removing iron and nickel carbonyl compounds prior or after the addition methanol and/or higher alcohols to the synthesis gas and optionally (I) cooling the withdrawn product in step (e); and (g) contacting the cooled product with a hydrogenation catalyst.
