Alkylation of Isobutane/Butene over Hexagonal Faujusite and Catalyst Regeneration

Alkylation of isobutane with butene on hexagonal faujusite catalyst in a fixed bed reactor was reported.Factors influencing the activity of the catalyst such as reaction time,reaction temperature and space velocity of butene were discussed.The experimental results showed that the catalyst possessed high initial activity which decreased quickly with time.Regeneration of the deactivated catalyst was conducted by passing carrier gas at given temperature through the catalyst,resulting in the recovery of its initial activity.
