Abstract
The objective of this work is simulating municipal solid waste gasification in fixed bed reactor. A comprehensive process model developed to simulate municipal solid waste (MSW) gasification in fixed bed reactor using an Aspen Plus simulation .To predict and analyze the municipal solid waste pyrolysis and gasification process in an updraft fixed bed more veritably and appropriately, numerical modeling based on Gibbs energy minimization was executed using the Aspen plus software v(9). Rstoic is a block that can be used to simulate a reactor with the unknown or unimportant reaction kinetic that will describe drying section(moisture evaporated).The Ryield model was describe the pyrolysis section, while the Rgibbs model was used for gasification section individually .The proposed model is used to forecast and analyze target performance parameter including syngas composition, lower heating value and carbon conversion rate under different conditions of gasification temperature , and ratios. The results indicate that is a good agreement between data and simulated data obtained using this model .The predicted optimum gasification temperature is about approximately 750°C, and the best ratio of air equivalent ratio is around 0.2 and feed rate 200 kg /hr.
