Abstract

The effects on CH4and N2separation performance of coconut shell charcoal by high temperature roasting were studied. Results indicate that the surface area increased firstly and then decreased with the increasing of the roasting temperature, and it is found that surface area of roasting 4 hours is higher. Furthermore, the experiment focused on the effect of high temperature roasting on activated carbon adsorption volume and separation coefficient. It is obvious that the adsorption volume increases earlier and then decreases with the increasing roasting temperature, and there are obvious turning points to adsorption volume of CH4and N2. Comparing various roasting time, it is found that adsorption volume in 4h is greater than that in 1h and also in 6h in the whole process. Separation coefficient decreases with increasing roasting temperature. When the temperature is higher than 800 °C, separation coefficient decreased rapidly. Considering the adsorption volume and separation coefficient, roasting 4 hours at 600 °C is selected for industrialized production.
