Abstract: The present disclosures and inventions relate to a method including the steps of: a) introducing a natural gas; b) reforming the natural gas; wherein the reforming step comprises contacting the natural gas with steam to produce a syngas; c) converting the syngas to a product mixture comprising an olefin, carbon dioxide, and hydrogen; wherein the converting step comprises contacting the syngas with a Co/Mn catalyst; and d) converting at least some process hydrogen and at least some process and/or external carbon dioxide to syngas by a reverse water gas shift reaction, and recycling such reverse water gas shift reaction produced syngas to before step c).

Abstract: The present disclosures and inventions relate to a method comprising: a) introducing a natural gas; b) reforming the natural gas; wherein the reforming step comprises contacting the natural gas with steam to produce a syngas; c) converting the syngas to a product mixture comprising at least one olefin and a byproduct comprising a paraffin and a gasoline; wherein the converting step comprises contacting the syngas with a Co/Mn catalyst; and d) converting the byproduct to syngas.

Abstract: The present invention provides a method and apparatus for recovery of reformed gas produced in a methanol plant during startup. In one aspect, the method for recovery of a reformed gas produced in a methanol plant during startup comprising: a) decreasing the temperature of the methanol plant reformed gas comprising (1) water in an amount no greater than 2.5 wt %, based on the total weight of the reformed gas, (2) methane in an amount that ranges from 1 wt % to 8 wt %, based on the total weight of the reformed gas, (3) hydrogen, (4) nitrogen, (5) carbon dioxide, and (6) carbon monoxide, to remove at least some of the water from the reformed gas; and b) using the water removed reformed gas as fuel in a steam reformer.
