PROCESS FOR PRODUCING UNSATURATED HYDROCARBONS

A process for producing unsaturated hydrocarbons which comprises contacting of paraffin, monoolefine and/or alkylaromatic compounds with a catalyst at a temperature within the range of from 400 to 700.degree.C in the presence of an inert gas and/or steam. The catalyst comprises a carrier with deposi...

Beschreibung
Zusammenfassung:	A process for producing unsaturated hydrocarbons which comprises contacting of paraffin, monoolefine and/or alkylaromatic compounds with a catalyst at a temperature within the range of from 400 to 700.degree.C in the presence of an inert gas and/or steam. The catalyst comprises a carrier with deposited thereonto an oxide compound of molybdenum in an amount of from 5 to 35% by weight of the catalyst. As the carrier use is made of a granulated porous crystalline silica modified with magnesia in an amount of from 1 to 20% by weight of TiO2, or a granulated magnesium-aluminium carrier consisting of 70 to 95% by weight of MgO and 5 to 30% by of from 400 to 700.degree.C till restoratio of catalytic activity of the catalyst. The process according to the present invention ensures a high selectivity; substantially simplifies temperature control in the reaction zone; avoids the possibility of formation of a hazardous mixture of hydrocarbons with oxygen; simplifies purification of waste waters.
