Fluid-bed studies of olefin production from methanol
With newly developed technology, conversion of methanol to hydrocarbons represents the final link in the production of premium transportation fuels from coal or natural gas. The methanol-to-gasoline (MTG) process has been developed. The more readily scaled fixed-bed version is the heart of the New Zealand Gas-to-gasoline complex, which will produce 14,000 BPD high octane gasoline from 120 million SCFD gas. The fluid-bed version of the process, which is also available for commercial license, has a higher thermal efficiency and possesses substantial yield and octane advantages over the fixed-bed. Successful scale-up was completed in 1984 in a 100 BPD semi-works plant near Cologne, West Germany. The project funded jointly by the U.S. and German governments and an industrial consortium comprised of Mobil; Union Rheinsche Braunkohlen Kraftstoff, AG; and Uhde, GmbH. The 100 BPD MTG project was extended recently to demonstrate a related fluid bed process for selective conversion of methanol to light olefins (MTO). The products of the MTO reaction make an excellent feed to the commercially available Mobile-Olefins-to-Gasoline-and-Distillate process (MOGD) which selectively converts olefins to premium transportation fuels . A schematic of the combined processes is shown. Total liquid fuels production is typically greater than 90 wt% of hydrocarbon in the feed. Distillate/gasoline product ratios from the plant can be adjusted over a wide range to meet seasonal demands. This paper describes the initial scale-up of the MTO process from a micro-fluid-bed reactor (1-10 grams of catalyst) to a large pilot unit (10-25 kilograms of catalyst).
