| Abstract | The relatively high sulfur content of coke produced during the upgrading of Athabasca bitumen makes it environmentally unsuitable as a fuel. Using heavy oil or bitumen as a binder we have attempted to coagglomerate these cokes with limestone, in an attempt to reduce emissions during combustion. By providing an environment where there is intimate contact between fuel and sorbent it was hoped that greater utilization of the sorbent could be achieved, compared to the systems where the sorbent is added separately to the combustion bed. Cokes from both Suncor and Syncrude operations were used in this investigation. The combustion tests on coke-sorbent agglomerates were carried out in a bench scaled fluidized bed apparatus at 850 degrees Celsius. Test results indicated sulfur capture of over 60% for Syncrude coke and over 50% for Suncor coke with a calcium to sulfur molar ration of 1:1. The presence of moisture did not appear to have any significant effect on sulfure caputre. Other variables investigated included: the role of binder, the effect of coke size and calcium to sulfur mole ratio. |
