文摘

The influence of temperature and hydrogen pressure on the regeneration of zeolite catalysts coked in the isobutane/butene alkylation is studied using in situ FTIR spectroscopy. By regeneration at suitable conditions, the activity of the catalyst for the alkylation reaction can be completely restored.
