Patent ID: 8721927

Claim:
A process for the gasification of solvent deasphalting process bottoms containing a spent solid adsorbent material recovered from a solvent deasphalting process to produce synthesis gas, the bottoms containing ash-forming constitutes, the process comprising: a. preparing a flowable slurry of the solvent deasphalting process bottoms consisting of the spent solid adsorbent material, asphalt and process reject materials; b. introducing the slurry of solvent deasphalting process bottoms as a pressurized feedstock into a membrane wall gasification reactor with a predetermined amount of oxygen and steam based on the carbon content of the feedstock; c. operating the gasification reactor at a temperature in the range of 900° C. to 1700° C. and a pressure of from 20 bars to 100 bars; d. subjecting the solvent deasphalting process bottoms to partial oxidation to produce hydrogen, carbon monoxide and slag derived from the spent solid adsorbent material; e. recovering the hydrogen and carbon monoxide from the reactor in the form of a hot raw synthesis gas; f. passing the hot raw synthesis gas to a steam generating heat exchanger to cool the hot raw synthesis gas and produce steam; g. recovering steam from the heat exchanger and introducing the steam into a turbine to produce electricity; and h. recovering the cooled synthesis gas.
