Abstract: “The aim of this work is to synthesis zeolite by using coal bottom ash from power plant and used as hydrogen sulfide (H2S) adsorbent to removal H2S from synthetic biogas. The zeolite was synthesized by fusion hydrothermal process of coal bottom ash, which was source of starting materials. Moreover, the obtained zeolite products were used for preparation of polyethylene composite material by using twin-screw extrusion process, polyethylene grafted maleic anhydride (PE-g-MA) as compatibilizer at various PE-g-MA: zeolite ratio (0.5:1, 1:1, 2:1 and 3:1, respectively) and different composition of Titanium Dioxide (TiO2) (0.25, 0.5, 0.75, 1, 1.5 and 2 phr). The results showed that the optimum condition for composite material as PEg- MA: zeolite ratio of 2:1 exhibited the highest adsorption capacity. Moreover, the equilibrium time and adsorption capacity at equilibrium increased with increasing the TiO2 loading. The results suggested that the polyethylene composite material filled with zeolite”
