    Arrhenius Pre-exponential factors

    I shuold clarify. I'm simulating an adsorbent bed for removal of H2 from the aforementioned mix of gases in aspen adsim (adsorption) and I need pre-exponential factors

    Shape Factors

    Hi, I'm wondering if anyone knows anything about shape factors. I've got an adsorption column (solid adsorbent in contact with a gas flow) and want to know what would give me a shape factor of 1? ex. beads, flat sheets, etc. Thanks.

    Gas-Gas separations

    Sorry, completely forgot to add the units. Its in cubic meters per day. I've got a gas feed consisting of CO, H2, CH4, CO2 and C2H6 and i'm looking to separate out CO and H2 for a recycle loop in my process - although i'm more interested in the CO than the H2. The % of the components are...

    Gas-Gas separations

    It would be a gas stream of volumes in the range of say, 100,000-200,000 per day. I'm interested primarily in removing H2 and more importantly, CO from CO2 and CH4. THx
