The carbon modified silica adsorbents were prepared by synthesizing and modifying zeolite Y type with activated carbon. This paper reports on effects of activated carbon loadings on the methane and nitrogen adsorption, structure and properties of carbon modified zeolite Y. With the increase in activated carbon loadings, the surface area, pore size and pore volume of the activated carbon loaded zeolite Y adsorbent decreased. The intensity of the diffraction patterns of zeolite Y decreased after the activated carbon was loaded. With increasing activated carbon loadings, the intensity of diffraction peaks decreased. Adsorption capacity of nitrogen (N2) was smaller than adsorption capacity of methane (CH4) by using activated carbon modified silica. When activated carbon loadings 30 wt., adsorption capacity of methane and nitrogen was 12.9317 wt. and 12.6115 wt., these were caused by difference in molecular weight. The molecular weight of nitrogen is bigger than molecular weight of methane.
