Catalytic Gasification of Bitumen Residues and Asphaltenes

The objective of this project was to examine the potential for catalytic gasification of bitumen fractions by adding catalyst precursors to the liquid feed. Unlike coal, where the solid state and high contaminant levels are a constraint, bitumen offers a more favourable opportunity. In the first phase of the project, the most effective catalyst among alkali metal- and alkaline earth metal-compounds for accelerating the rate of steam gasification of solid coke was determined. Metal carbonates, oxides, and stearates were examined, added as dry materials and as emulsified suspensions. In the second phase of the study, the kinetics of reaction of the most effective catalysts were determined.
