Integrated gas to olefins process with recovery and conversion of by-products

摘要

This invention provides a method for producing a light olefin product from a hydrocarbon feed, as well as a method for converting by-product to light olefin. In one embodiment, the process includes production of a synthesis gas from the hydrocarbon feed, conversion of the synthesis gas to an oxygenate composition, and conversion of the oxygenate components to an olefin stream. A by-product stream can also be separated and ultimately converted to additional light olefin product.
