ABSTRACT:
Dewaxing a waxy feedstock is achieved by submerging the dewaxing catalyst bed in the waxy feedstock and removing gaseous products out of contact with the catalyst by agitating the bed to prevent further cracking or polymerization. Catalyst aging during dewaxing is significantly reduced by operating the dewaxing reactor within a narrow low temperature range.
