Light olefin production, skeletal olefin isomerization and etherification for oxygenated fuel production
- ARCO Chemical Company, Newton Square, PA (United States)
ARCO`s newly developed SUPERFLEX{sup SM} process offers opportunities to product high yields of light olefins, from a variety of readily available refinery and petrochemical feedstocks. The process is unique in that it employs a catalytic reactor system which is lower in capital and operating costs than conventional steam cracking reactors. The SUPERFLEX process is also more selective for production of propylene and butylenes (including isobutylene) than conventional steam cracking operations. The C{sub 4} product stream from the SUPERFLEX process contains about 20 to 30 percent isobutylene. The SUPERFLEX C{sub 4} product is, therefore, an excellent feedstock for producing MTBE via reaction of the contained isobutylene with methanol. After MTBE production, the isobutylene depleted C{sub 4} stream may be recycled to the SUPERFLEX process to produce additional isobutylene and propylene. This paper will focus on the chemistry and mechanism of catalytic cracking and skeletal olefin isomerization. In addition, there will be some discussion on catalyst activation, life and characterization.
