Catalyst system for heterogenous catalysis of an isobutylene polymerization reaction

A method for preparing a catalyst system for heterogenous catalysis of an isobutylene polymerization reaction, the method comprising:

• forming an alumina support in which said alumina support has pores formed therein;
• and
• reacting a BF3/methanol catalyst complex with said alumina support, wherein a ratio of methanol to BF3 in said catalyst complex ranges from 0.5 moles of methanol per mole of BF3 to 2 moles of methanol per mole of BF3, wherein a concentration of said catalyst complex on said alumina support ranges between 10% and 40% by weight, the step of forming comprising:
• extruding said alumina support so as to have a significantly greater length dimension than a diameter dimension.
