The low volatiles and high sulfur content of the coke produced during the upgrading of Athabasca bitumen makes it unsuitable as a fuel. However, the coke can be used as an adsorbent to recover heavy oil or bitumen from process waste streams by using a liquid-phase agglomeration technique. It has been found that bitumen can act as a collector for certain sulfur dioxide capture agents, allowing them to be incorporated into the coke agglomerates during the oil recovery operation. Three sulfur sorbents-lime, hydrated lime, and limestone- and cokes from both Suncor delayed coking and Syncrude fluid coking operations were used in this investigation. This coagglomerated material could be used as an ancillary fuel for generation of process energy for bitumen recovery. During combustion of the coagglomerates, sulfur dioxide capture was found to depend mainly on the calcium to sulfur mole ratio, the combustion temperature, and the type of coke. The efficiencies of the three agents used in this investigation for reducing sulfur dioxide emissions have been compared.
