Abstract: Coker gas oil (CGO), heavy cycle oil (HCO), and a CGO-HCO blend were treated by solvent refinement and then cracked in a FCC pilot plant over a commercial Y zeolite-based catalyst at selected reaction conditions. The experimental setup simulates the cracking behavior of different feed streams in an FCC unit using different processing schemes. The processing alternative that can yield the highest conversion and maximum light oil production was evaluated. Blending unrefined CGO into FCC feedstock results in decr… Show more

“…The relation of EBVRHC heavy oil conversion to the Kw factor (for Kw variation between 11.07 and 11.91) is given in Eq. ( 11): Conversion ¼ 0:1787e 0:5013Kw R ¼ 0:99; av: error ¼ 1:7 % (11) The relation between H-oil gas oils Kw factor, the amount of FCC FCC slurry oil (SLO) processed along with the vacuum residue in the LNB H-oil hydrocracker (Fig. S3), and the variation of the slope of conversion reduction as a function of FCC SLO content in the vacuum residue hydrocracking feed (Tab.…”

“…Moreover, the slope of the FCC conversion decrease during processing of feed blends, which contain secondary gas oils, can be different [1]. Therefore, the processing of vacuum residual oils having different quality in the cokers and in the ebullated-bed vacuum residue hydrocrackers can yield VGOs having different quality that in turn can affect the FCCU performance, where these secondary gas oils are converted [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

“…Wang et al reported a combined process that extracted the easily cracked saturated hydrocarbons in the HCO and CGO with furfural first and then mixed them back to the FCC unit to increase the yield of light oil. Nevertheless, the raffinate oil containing plenty of aromatics was not effectively utilized.…”

“…Wang et al proposed a novel conceptual process to catalytically crack residue and reform the naphtha simultaneously. They further developed other similar technologies to treat vacuum residue, vacuum gas oil, coker gas oil, and FCC cycle oil. The two-stage riser FCC (TSRFCC) technology, another coupled FCC technology that has been applied in some subsidiaries of China National Petroleum Corporation (CNPC) in China, has enormous advantages in flexible operation, adaption for different feedstocks, and restraint on the overcracking of intermediate products. This technique has been introduced to in situ upgrade the FCC naphtha, synergistically process the coker gas oil, and yield light olefins. On the basis of the TSRFCC technology, we propose a novel FCC process for processing high-acid crude oil in this paper that can reduce the overcracking of light fractions and increase the conversion of heavy fractions.…”
