ABSTRACT:
A method is provided which can be used to quickly and easily take a fixed-bed of solid acid olefin polymerization catalyst out of service without causing any significant catalyst deactivation. The method involves substituting a substantially olefin-free hydrocarbon fluid for at least a portion of the olefin-containing feedstock to the polymerization process, wherein the substantially olefin-free hydrocarbon fluid boils within the range from about 20.degree. to about 250.degree. C. and contains at least about 5 vol. % aromatics.
