Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas exists, it will cause corrosion and damage to facilities. In this study, to produce energy in the form of flammable biogas, different combinations of kitchen waste and poultry manure were used to optimize and increase the amount of biogas according to the available organic matter composition. The results showed the best combination of poultry manure and kitchen waste in proportion. Equivalence and the adsorption of hydrogen sulfide gas with adsorbents (ironstone) was examined to the aim of the production of impurities reduction in gas. This indicates the removal of the gas in a different time period than the produced gas. In this study, three modified Gompertz models, modified logistics and no delay phase model were investigated to determine which model predicts the best biogas production. The first two models, Gompertz and modified logistics, well matched the data with accuracy, but the No-lag model shows some errors due to lack of the delay phase consideration in biogas production. Considering the amount of biogas produced in different digesters, the results show that the potential for biogas production for the ratio (KW + CM) with the amount of .11000ml is more than other cases.
