Title:
フィッシャー-トロプシュ法テールガス中のオレフィンの縮合
Document Type and Number:
Japanese Patent JP4790987
Kind Code:
B2
Abstract:
Light olefins including LPG contained in unreacted tail gas from a Fischer-Tropsch process are catalytically condensed using an acidic oligomerization/aromatization catalyst to form higher molecular weight C5+ products. Thus, C3-C4 olefins are readily separated from the tail gas and upgraded to more valuable products. In one embodiment, the condensation is conducted on a mixed gas stream of fresh synthesis gas and tail gas from a Fischer-Tropsch process. In another embodiment, the condensation is conducted on a syngas feed to a Fischer-Tropsch reactor and removes a significant portion of catalytically poisonous nitrogen compounds.
