1. A fluidized catalytic cracking apparatus for co-processing an unenriched renewable fuel oil and a petroleum fraction, comprising:
a riser having at least a first injection port and at least a second injection port; the at least first injection port for injecting the petroleum fraction; the at least second injection port for injecting the unenriched renewable fuel oil into the riser, the at least second injection port being corrosion resistant to the unenriched renewable fuel oil; at least one tank for storing and delivering the unenriched renewable fuel oil, the at least one tank being corrosion resistant to the unenriched renewable fuel oil; and a preheater to preheat the unenriched renewable fuel oil prior to injecting the unenriched renewable fuel oil into the riser,wherein the unenriched renewable fuel oil is derived from a non-catalytic conversion of a cellulosic biomass and comprises a carbon content of at least 40 wt. % on a moisture-free basis, an oxygen content in the range of between 20-50 wt. % on a moisture-free basis, and a water content in the range of between 10-40 wt. %, andwherein the at least second injection port is:
designed to inject less than 10 wt. % of the unenriched renewable fuel oil into the riser relative to the total amount of the petroleum fraction injected into the riser; and located proximate the at least first injection port. |
