The invention discloses a heavy oil product treatment
processing method. The method comprises a hydrogenation pretreatment device, a
solvent deasphalting device, a hydrogenation treatment device and a catalytic
cracking device, wherein the hydrogenation treatment device comprises a hydrogenation pretreatment reaction area and a hydrogenation treatment reaction area; the
processing method comprises the following steps:
residual oil raw material generated oil is subjected to
fractional distillation after being reacted through a hydrogenation pretreatment unit to obtain light fraction and heavy fraction, wherein the heavy fraction is treated after entering the
solvent deasphalting device so as to obtain deasphalted oil and deoiled
asphalt, and the light fraction orderly passes through the hydrogenation pretreatment reaction area and the hydrogenation treatment reaction area which are in series connection after mixing with the deasphalted oil and
hydrogen; gas-liquid separation is performed on reaction
effluent of the hydrogenation treatment reaction area, and a
gas phase is recycled back to the hydrogenation pretreatment reaction area and / or the hydrogenation treatment reaction area; a
liquid phase directly enters a catalytic
cracking reaction area to perform catalytic
cracking reaction, and
effluent of the catalytic
cracking reaction is separated to obtain
dry gas, liquefied gas, catalytic-cracked
gasoline fraction, catalytic-cracked diesel fraction, catalytic-cracked heavy
cycle oil and catalytic-cracked oil
slurry. The stable operation period of the device can be prolonged by use of the method disclosed by the invention.
