        abstract = {Pyrolysis of high-ash sewage sludge (HASS) is a considered as an effective method and a promising way for energy production from solid waste of wastewater treatment facilities. The main purpose of this work is to build knowledge on pyrolysis mechanisms, kinetics, thermos-gravimetric analysis of high-ash (44.6) sewage sludge using model-free methods \& results validation with artificial neural network (ANN). TG-DTG curves at 5,10 and 20 {\^A}oC/min showed the pyrolysis zone was divided into three zone. In kinetics, E values of models ranges are; Friedman (10.6{\^a}??306.2 kJ/mol), FWO (45.6{\^a}??231.7 kJ/mol), KAS (41.4{\^a}??232.1 kJ/mol) and Popescu (44.1{\^a}??241.1 kJ/mol) respectively. {\^I}?H and {\^I}?G values predicted by OFW, KAS and Popescu method are in good agreement and ranged from (41{\^a}??236 kJ/mol) and 53{\^a}??304 kJ/mol, respectively. Negative value of {\^I}?S showed the non-spontaneity of the process. An artificial neural network (ANN) model of 2 * 5 * 1 architecture was employed to predict the thermal decomposition of high-ash sewage sludge, showed a good agreement between the experimental values and predicted values (R2 {\^a}{\copyright}3/4 0.999) are much closer to 1. Overall, the study reflected the significance of ANN model that could be used as an effective fit model to the thermogravimetric experimental data. {\^A}{\copyright} 2018 Elsevier Ltd}
