Synthesis of Al2O3-ZnO composite with high surface area as sulphur adsorbent catalyst

Activated alumina and zinc oxide both have been used as a sulphur remover catalyst in different applications such as gas - oil - and petrochemical Indus tries. One of the main applications of activated alumina is removing of sulphur from sour natural gas in clause process and also ZnO can be used as a catalyst agent or support performing a Fischer Tropsch reaction to convert a mixture of carbon monoxide and hydrogen to hydrocarbons [1]. Apart from gas, oil and petrochemical processing, removing of the sulphur, to have clean environment also is very important. In this study we have tried to investigate synthesis of alumina and zinc oxide when they prepare in chemical root at the same time. Precipitation of alumina and zinc oxide was performed by mixing of aluminum chloride and zinc acetate in different proportions. Calcined materials were characterized by DSC, XRD, BET, SEM and FTRI to see phase distribution and its effect on surface area activation. Also dispersion of different proportions of Al2O3-ZnO to have maximum surface area was evaluated.
