A process for preparing a catalyst provided in the form of a metal oxide catalyst having at least one element selected from Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce. The catalyst is subjected to an aftertreatment to increase the proportion of the M1 phase, by contacting the catalyst with steam at a pressure below 100 bar or by contacting the catalyst with oxygen to obtain an aftertreated catalyst. The aftertreated catalyst may be used for oxidative dehydrogenation processes.

The present invention relates to a method for oligomerization of ethylene, comprising the steps:

Method for oligomerization of ethylene

The present invention relates to a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of solvent and homogenous catalyst, comprising the steps of: (i) feeding ethylene, solvent and catalyst into an oligomerization reactor, (ii) oligomerizing the ethylene in the reactor, (iii) removing a reactor outlet stream comprising solvent, linear alpha-olefins, ethylene, and catalyst from the reactor via a reactor outlet piping system, (iv) transferring the reactor outlet stream to a catalyst deactivation and removal step, and (v) deactivating and removing the catalyst from the reactor outlet stream, characterized in that at least one organic amine is added into the oligomerization reactor and/or into the reactor outlet piping system.

A method and device for the catalytic decomposition of laughing gas in a laughing-gas-bearing gas. The method includes diluting the laughing-gas-bearing gas with a diluting gas, while forming a laughing-gas-bearing charge gas. The laughing-gas bearing charge gas is passed through a heat-exchange step where heat exchange occurs with an exhaust. A heating step occurs for occasional heating of the laughing-gas-bearing charge gas in a fixed-bed reactor for catalytic decomposition of the laughing gas. In some embodiments the diluting gas is dried, and at least a part of the exhaust from the catalytic decomposition of the laughing gas is mixed with the laughing-gas-bearing charge gas upstream of the catalytic decomposition of the laughing gas.

Process and device for decomposing laughing gas

A device and method for the decomposition of laughing gas including a gas inlet for supplying a laughing-gas-bearing gas; a first heat-exchanger for the exchange of heat between an exhaust and the laughing-gas-bearing gas; a heating device for occasional heating of the laughing-gas-bearing gas and a fixed-bed reactor in which a catalyst is included in order to decompose the laughing gas. The device also includes a gas outlet, through which exhaust leaving the fixed-bed reactor can be taken away through the heat exchanger. The device may be used to implement a method where the catalyst for decomposition of laughing gas is maintained at temperatures below 800&#xb0; C. and in which the fixed-bed reactor is arranged as an adiabatic reactor.

A process for separating hydrogen from a gas flow having an oxygen constituent and including predominantly hydrogen, nitrogen, oxygen, carbon dioxide, carbon monoxide, methane and/or other hydrocarbons, as well as a device for conducting the process, is disclosed. The gas flow undergoes a process to thermally convert oxygen prior to the pressure swing adsorption process.
