Studies on the absorption properties of isopropyl alcohol on activated carbon by Grand Canonnical Monte Carlo Simulation

The effect of pressure, temperature, microporous size of activated carbon on adsorption process of isopro-pyl alcohol on activated carbon was studied by Grand Canonical Monte Carlo Simulation. The result shows that the adsorption process can be described reliably by the activated carbon microporous model. When the pressure is 1kPa, the adsorption quantity of activated carbon with microporous size of 1. 7nm is higher. While activated carbon with microporous size of 2. 0nm has higher adsorption quantity when the pressure is 2-4kPa. At the pressure of 4 -10kPa, the adsorption quantity of activated carbon with microporous size of 2. 5nm is higher. The adsorption quantity of the system which jaws width of activity carbon is 2. 5nm is higher. The best recovery temperature of iso-propyl alcohol desorbed from activated carbon is 140℃.
