Abstract:
     The present invention relates to a process for directly preparing low-carbon olefine by using reaction of low-carbon paraffine with carbon dioxide. Said invented process adopts a carrier-type or non-carrier type metal oxide catalyst containing elements of Cr-Mn-K. The low-carbon paraffine can be high-convertibly and high-selectively converted into low-carbon olefine by the action of said catalyst under the conditions of reaction temp. 300-900 deg.C, reaction pressure 0.01-5.0 MPa and reaction space velocity 100-5000 h-1. Said invention can be used for converting a large amount of ethane contained in oil-gas field into ethylene, and can be used for converting ethane contained in catalytic dry gas into ethylene. Said reaction process is simple, easy to operate and popularize for application.
