ABSTRACT:
Solid catalysts including solid phosphoric acid catalysts are regenerated in-situ in a multi-step method. A sequence which includes depressurization, soaking in an aromatic hydrocarbon-containing liquid at a high temperature and pressure, depressurization and draining is repeated three times. The regeneration removes polymers formed from olefinic reactants.
