To find out the Co-pyrolysis characteristics of Dianchi Lake sludge and coal,Dianchi Lake sludge was introduced into coal pyrolysis process. In this paper,the pyrolysis experiments of Dianchi Lake sludge and coal were carried out by TG and TGA. Results show that the TG and DTG profiles of Dianchi Lake sludge were similar to coal, but different from coal under various blending ratios.Interaction was observed between the solid phases of Dianchi Lake sludge. The results provide a reference for further study on co-pyrolysis of Dianchi Lake sludge and coal to a certain extent.

Process Simulations

Simulation and study on Texaco gasification of semi-cokes prepared by DG coal pyrolysis process has been carried out by using Aspen Plus. The possibility that pyrolytic semi-cokes is used as the raw materials is discussed. Sensitivity study runs are performed to analyze the effects of oxygen-to-char mass ratio, mass percentage of char in char water slurry and gasification pressure on the gasification process. Simulations indicate that molar percent content of effective components (CO+H2) reaches as high as 67.94% under operational conditions which oxygen-to-char mass ratio is 0.75; char water slurry concentration is 62.5% and gasification pressure is 4.0MPa. So semi-cokes made by DG coal pyrolysis process is the excellent raw materials for gasification. Sensitivity analysis show that oxygen-to-char mass ratio and mass percentage of char in char water slurry are the main factors that affect the gasification process; gasification pressure has little effect on the results of char gasification.
