Patent ID: 7540952

Claim:
A thermo-catalytic process using at least two fluid catalytic cracking unit reactors, the method comprising the steps of: supplying a petroleum feedstock to a first fluid catalytic cracking reactor; supplying a vegetable oil feedstock to a second fluid catalytic cracking reactor; supplying a catalyst to the first catalytic cracking reactor and to the second catalytic cracking reactor; contacting the petroleum feedstock with the catalyst inside the first fluid catalytic cracking reactor so as to facilitate a catalytic cracking reaction; catalytically cracking the petroleum feedstock and producing a first effluent stream comprising a reaction product; separating the reaction product in the first effluent stream; contacting the vegetable oil feedstock with the catalyst inside the second fluid catalytic cracking reactor so as to facilitate a catalytic cracking reaction; catalytically cracking the vegetable oil feedstock and producing a second effluent stream comprising a reaction product; separating the reaction product in the second effluent stream; and regenerating the catalyst in a regenerator from the first and second fluid catalytic cracking reactors such that the catalyst may be recycled to the first and second catalytic cracking reactors as a regenerated catalyst.
