Title:
フィッシャー・トロプシュ合成粗生物を熱分解とオリゴマー化の使用によって高品位化する方法
Document Type and Number:
Japanese Patent JP2005523319
Kind Code:
A
Abstract:
A process for upgrading a Fischer-Tropsch feedstock which comprises (a) recovering from a Fischer-Tropsch reactor a Fischer-Tropsch wax fraction and a Fischer-Tropsch condensate fraction, wherein the Fischer-Tropsch condensate fraction contains alcohols boiling below about 370° C.; (b) contacting the Fischer-Tropsch condensate fraction with a dehydration catalyst in a dehydration zone under dehydration conditions pre-selected to convert at least some of the alcohols present in said fraction into olefins and recovering a first intermediate effluent from said dehydration zone; (c) pyrolyzing the paraffins in the Fischer-Tropsch wax fraction in a thermal cracking zone under thermal cracking conditions pre-selected to crack the Fischer-Tropsch wax molecules to form olefins and collecting a second intermediate effluent from the thermal cracking zone; (d) passing the first and second intermediate effluents recovered from steps (b) and (c) to an oligomerization zone containing an oligomerization catalyst under oligomerization conditions to form an oligomerization mixture having a higher molecular weight than either of said first and second intermediate effluent; (e) hydrofinishing the oligomerization mixture in a hydrofinishing zone; and (f) recovering from the hydrofinishing zone a C10 plus hydrocarbon product, most preferably a lubricating base oil.
