Abstract
A fluid coking-gasification process for converting heavy hydrocarbonaceous chargestocks to lower boiling products in which a zeolitic material is use to mitigate slagging in the gasifier, especially when the zeolite material is spent catalytic cracking catalyst. The zeolite material is added either directly into the gasifier on it is mixed with the coke passing from the heating zone to the gasification zone.
