The feasibility of simultaneous residue coking and partial gasification of coal was demonstrated using a laboratory unit. In the process scheme, petroleum residue was upgraded to low metal and carbon residue liquid product suitable as feed to fluid catalytic cracking. The coal was upgraded to gaseous products suitable for process heaters and solid products for fueling power plants. The reactions took place in a single reactor. The coal was gasified at the bottom section of the reactor to generate heat and gaseous products; it was devolatized in a fluidized bed in the middle section for additional gaseous product. The petroleum residue was coked over the hot coal char in the fluidized state and hot fluidizing gas without external heat addition. This led to improved thermal efficiency, and reduced capital and operation costs. The liquid yield based on residue was high and could exceed 100% due to contributions from coal pyrolysis. The liquid product could be used as fluid feedstock. The gaseous products resulting from coal pyrolysis and partial gasification had heating value between 300-400 Btu/SCF depending on the extent of coal gasification. Sixty-six percent of the sulfur compounds in the coal was removed, leading to a solid product with 2% sulfur content. This solid product was easy to burn and could be used to fuel power plants. 8 references.
