OP-3-1should be efficient in terms of tar removal, economically feasible, but moreimportantly, it should not affect the formation of useful gaseous products.In this paper a novel and cheap catalyst is introduced for the gasification process.This catalyst acts as a suitable bed material promoting char gasification reactions,changing the product gas composition, increasing its heating value and reduces thetar yield. Claim has been approved by thermogravimetry analysis coupled with gaschromatography tests and by comparing results with pure biomass and also other tarcracking catalysts. Biomass gasification also have been done in fluidized bed reactorwith application of novel catalyst which results show significant improvement ingasification process. A kinetic model was presented for the pyrolysis step and it wasfitted to experimental results in order to find its parameters. Kinetic model has beenused for modeling catalytic gasification in fluidized bed employing previousdeveloped hydrodynamic models [5]. Modeling results are comparable withexperimental results. This new catalyst can be known as a breakthrough in order toimprove gasification process for industrial purposes.[1]. Sutton D, K.B., Ross J. R.
