C{sub 4} chemistry in a modern conversion refinery; C4-Chemie in einer modernen Konversionsraffinerie

Abstract

Using the example of one of Europe`s most modern conversion refineries, the Oberrheinische Mineraloelraffinerie Karlsruhe, the effects of changes in the process conditions in the fluidized-bed catalytic cracker are described, e.g.: Full utilisation of the capacities of the downstream units for alkylation and ethering of the C{sub 4} fraction; changes in the octane rating of the gasoline pool, levelling of the C{sub 4} balance of the refinery. The following process variables of the catalytic cracking system were investigated: c/o ratio, reactor temperature, ZSM-5 additive. The use of ZSM-5 increases the additional isobutane consumption of the plant; on the other hand, it will raise the octane rating by about 0.5 MOZ while the gasoline pool decreases slightly. The opposite effect is achieved by raising the c/o ratio: The gasoline pool grows while the octane rating remains constant. If the reactor temperature in the FCC plant is raised, the isobutane shortage resulting from the ZSM-5 additive can be compensated to some extent, the C{sub 4} balance of the refinery will be improved, and the octane rating will be clearly raised.
