Abstract: A method for preparing a butene trimer from the butene containing various components, and a method for preparing a high viscosity alkylate by using the butene trimer are provided to improve the selectivity to a butene trimer. A method for preparing a butene trimer from the butene containing various components comprises the steps of oligomerizing a butene isomer mixture in the presence of a porous acid catalyst; and isomerizing the isomerized butene obtained as a by-product by the oligomerization so as to recirculate it into the oligomerization or to provide it for dehydrogenation. Preferably the butene isomer mixture is a C6 fraction obtained from the aqueous cracking process or the fluidized catalytic cracking(FCC) process.
