Abstract
The present invention discloses a process for producing light olefins, comprising the steps of: i) contacting a feed comprising a monohalo-methane with a molecular sieve catalyst under the conditions: a reaction temperature in the range of from 350.degree. C. to 600.degree. C., a reaction pressure in the range of from 0.05 to 1.1 MPa (absolute), and a weight hourly space velocity of the monohalo-methane in the range of from 0.1 to 100 hour.sup.-1, to give an effluent comprising ethylene, propylene, and hydrogen halide; and ii) isolating ethylene, propylene and hydrogen halide from the effluent.
