AbstractA liquid phase agglomeration technique is being developed to incorporate sulphur sorbents into carbonaceous fuels. This paper reports a summary of the work describing a number of case studies, based mainly on the work from the authors' laboratory, to illustrate the diverse applications of the technique. Athabasca petroleum cokes obtained from Suncor delayed coking and Syncrude fluid coking operations and a high sulphur Nova Scotia coal were used for these tests. Static combustion tests at 850°C were carried out in a muffle furnace and compared with results found for a bench scale fluidized bed unit at the same temperature. It has been demonstrated that greater utilization of the sulphur sorbent can be achieved by cogglomerating the fuel with sulphur sorbents, providing an environment in which there is intimate contact between fuel and sorbent compared with systems in which the sorbent is added separately to the combustion bed. Coagglomeration of petroleum cokes and lime (Ca:S molar ratio of 1:1), resulted in a percent sulphur capture of at least, 30% to over 80% depending upon the source of carbon and the test conditions (fluid bed vs muffle furnace).
