Abstract
A new technology is proposed by the directly integrated supercritical fluid extraction and fluidized thermal conversion process, which was named the integrated supercritical fluid extraction and fluid thermal conversion (ISFTC) process. In the extraction unit of ISFTC, the heavy feedstock was separated into deoiled asphalt (DOA) and deasphalted oil (DAO). The DOA phase is fed to a fluidized-bed thermal convertor (FTC) without solvent separating, using hot coke to supply the heat. DAO will be qualified for fluid catalytic cracking (FCC) processing. The proposed process avoids the feedstock quality limit for both FCC and delayed coking (DC). It increased the overall liquid yield of vacuum residue (VR) upgrading and solved the problem of solvent recovery for the solvent–DOA phase at the bottom of the supercritical fluid extraction unit. A continuous laboratory apparatus was built to prove the concept. A Chinese petroleum residue was processed by the built apparatus at appropriate operating conditions. The to...
