To optimize the performance of an adsorption bed, layered beds of activated carbon and zeolite 5A are used for multicomponent gas separation (H 2 : 72.2%, CO 2 : 21.6%, CO: 2.03%, CH 4 : 4.17%). The adsorption dynamic characteristics were studied experimentally and theoretically using layered beds of activated carbon and zeolite 5A at 8 atm adsorption pressure and 16.67 L/min feed rate. Non-isothermal and non-adiabatic models, based on a linear driving force model and Dual-Site Langmuir adsorption isotherm model, were used. As the carbon ratio increased, the average velocity of CH 4 wavefront became slow, and wavefronts of CO and CO 2 propagated quickly on average.

“…Also, a complete non-isothermal and non-adiabatic dynamic model was adopted with the following assumptions [11][12][13]:…”

“…I spoke of this person as a creature of modernity, conscious, even proud, of living in a mixed-up world having a mixed-up self. 44 21 This is the conception of cosmopolitanism as consisting in an individual experience characterized by "a bit of this and a bit of that", as Salman Rushdie has put it. 45 22 Yet does "cosmopolitanism" have to involve this detached attitude, do cosmopolitans need to be "rootless", "elitist", and even "parasitic" (according to conservative British philosopher Roger Scruton), or at the very least mixed up, as they have been portrayed by many commentators?…”

No one disapproves more, or is in the habit of expressing his disapprobation more strongly than I do of the narrow, exclusive patriotism of former ages which made the good of the whole human race a subordinate consideration to the good, or worse still, to the mere power & external importance, of the country of one’s birth. I believe that the good of no country can be obtained by any means but such as tend to that of all countries, nor ought to be sought otherwise, even if obtainable.Mill’s re..

“…Further, it is supposed that all the stages of the cycle are carried out at the constant temperature T 0 and that adsorption equilibrium is instantaneously established between the filtered flow and the adsorbent. This cycle is an idealization of the simplest working cycle of the pressure swing adsorption process, which is widely used in gas fractionation technologies [5,6].…”
