Biomass steam gasification is a conversion process to produce a fuel gas to be used in power systems. The efficiency of these systems are extremely affected by the composition of the fuel gas that depends on various factors, such as steam to biomass ratio, equivalence ratio, process temperature, fuel composition and moisture content, all correlated each other. High temperature gas sensor are a very promising devices for the measure of the gas quality directly where fuel gas is generated and for the control of the gasification efficiency. Nano-powders of LaFeO3 perovskite were synthesized and characterized as starting material for chemoresistive gas sensors suitable for these high temperature applications, in order to evaluate how synthesis operating conditions affect sensor’s quality
