Claim:
1. A process for oligomerizing light olefins comprising: providing a first oligomerization reactor zone containing a first oligomerization catalyst selected from a zeolitic catalyst or a solid phosphoric acid catalyst; providing a second oligomerization reactor zone containing an amorphous silica alumina catalyst; providing an oligomerization feed stream comprising C providing a first conduit control valve to control flow of a first oligomerization feed; providing a second conduit control valve to control flow of a second oligomerization feed; controlling said conduit control valves to split said oligomerization feed stream into said first oligomerization feed and said second oligomerization feed in aliquot portions of equivalent compositions; feeding said first oligomerization feed to said first oligomerization reactor zone to yield a first product comprising aliphatic olefins; feeding said second oligomerization feed to said second oligomerization reactor zone to yield a second product comprising naphthenes; oligomerizing said first wherein the concentration of naphthenes in the second product is greater than in the first product; varying the aliquot portions of said feed streams to achieve desired quantity of aliphatic olefins or naphthenes desired; recovering the first and second products.
