Abstract

| A new method for producing zeolitic monoliths is used to produce a ZSM-5 based monolith for gas separation. The new method involves the 3DFD (Three Dimensional Fiber Deposition) printing of several layers of zeolite fibers on top of each other in a well-defined way, resulting in an open monolithic structure with open and inter-connected channels. The monolithic structure, consisting of ZSM-5 zeolite, was characterized with SEM, Ar and Hg porosimetry. Single component isotherms of CO2, CH4 and N2 were recorded on the 3DFD-printed ZSM-5 monolith, at different temperatures (283 K, 291 K, 302 K and 309 K) using a gravimetric method. Isosteric heats of adsorption show that CO2 is the most strongly adsorbing component, in order followed by CH4 and N2. The monolithic structure was subjected to breakthrough separation experiments with CO2/N2 and CO2/CH4 gas mixtures. Excellent separation performance is achieved. Moreover, the ZSM-5 monolith can be easily regenerated in isothermal conditions. |
