Selective isomerization and oligomerization of olefin feedstocks for the production of turbine and diesel fuels

A process for manufacturing turbine and/or diesel fuels, comprising:

• providing an alcohol feedstock;
• dehydrating said alcohol with at least one solid catalyst at temperatures ranging from about 200° C. to about 400° C. to produce an olefin mixture;
• oligomizering said mixture directly with at least one metallocene based Ziegler Natta catalyst and methylaluminoxane (MAO) cocatalyst to produce an oligomer mixture including unreacted internal olefins and oligomers;
• separating said unreacted olefins by temperature controlled distillation;
• converting said unreacted olefins to a distribution of oligomers with a bimetallic isomerization/oligomerization catalyst having a metallocene based catalyst in conjunction with an isomerization catalyst to produce oligomers formed through 1,2-addition;
• and hydrogenating and distilling said oligomers to produce fully saturated diesel and turbine fuels.
