In this paper, a process model of coal gasifier was developed using MATLAB, MS EXCEL. The proposed model in this paper was developed to predict syngas compositions correctly through calculating heat and mass balances and detail design for gasification in reactor. Furthermore, the proposed model was made to calculate carbon conversion and cold gas efficiency which represent the performance of gasifier. In order to validate the proposed model, result of syngas compositions was compared with RGibbs model in ASPEN PLUS for 4 coals which have experimental results of shell gasifier. Errors of results between experimental data and the proposed model is within 0.5%, the standard deviation of errors is 0.27. The value is smaller than 1.27 of RGibbs model, so that results from the proposed model is stable for prediction of syngas compositions. Carbon conversion and cold gas efficiency 4 coals were about 99% and 80% for as same with typical performance of Shell gasifier. In addition, the proposed model calculated volatile yields and reaction coordinates for 4 coals. Specially, it notices that reaction coordinates of gasification depend on coal type and what kinds of reaction are superior in gasification for each coal. The proposed model will be used effectively for process modeling of gasification plant process.
