Method for increasing light olefin yield by conversion of a heavy hydrocarbon fraction of a product to light olefins |
| abstract |
The present invention comprises contacting an oxygenate feedstock in a first reactor with a non-zeolitic molecular sieve catalyst under first conditions effective to produce a first product comprising a light olefin and a heavy hydrocarbon fraction; Separating the light olefins from the heavy hydrocarbon fraction; Feeding a heavy hydrocarbon fraction to a second reactor; And subjecting the heavy hydrocarbon fraction in the second reactor to second conditions effective to convert at least a portion of the heavy hydrocarbons into light olefins, wherein the yield of light olefins is increased during conversion of the oxygenate to olefins. will be. |
