In San Juan pistachio production has grown in recent years due to the great interest in the consumption of pistachio nut, which has health benefits. Production waste from industrialization represents a problem, because it is accumulated and stored in acceptable ways occupying space and generating unpleasant odors among others. Gasification of waste for energy represents advantages from the economic point because it gives added value to these materials, on the one hand and on the other, environmentally can say that the balance of C is zero because it is residual biomass. The aim of this work was to study the performance of the gasification process residue pistachio steam, as it improves yields syngas production, based on thermodynamic analysis to improve the gas composition using an equilibrium model to predict the gas composition based on the minimization of Gibbs free energy. : According to the results obtained by the model, the more efficient process requires conditions of temperatures between 450 °C and 600 °C. For lower moisture content, the efficiency is increased due to the presence of water in the sample, which consumes energy to reach the state of superheated steam. In turn, it improves performance with increasing gasifying agent (steam) and with the decreasing the amount of oxygen present in gasification. . Economic analysis suggests that the gasification process is desirable because it provides solution to the problem of environmental pollution with low operating costs.
