1. A method for determining an optimal monolith geometry for a honeycomb monolith comprising the steps of:
a. calculating a design index, S, for the monolith according to the following formula:S=trtf=1/KL/u=uKL=V(OFA)(K)(L) wherein tr is the reaction time-scale for CO2 capture, tf is the flow time-scale for CO2 capture, u is the velocity of feed gas inside the channel, K is the reaction rate for CO2 capture, L is the length of the monolith, OFA is the open frontal area of the monolith, and V is the velocity of feed gas outside the monolith, wherein the monolith comprises a sorbent having a zeolite composition; b. determining if S is equal to or less than 0.4 and greater than or equal to 0.01; c. changing one or more monolith parameters to make S equal to or less than 0.4 and greater than or equal to 0.01 such that the monolith is characterized by the length, L, being from about 0.3 m to 1 m, the diameter, D, being from about 0.3 m to about 1 m, the open frontal area, OFA, being from 0.4 to 0.9, and a cell density, CPSI, from at least 500 cells per square inch to 5000 cells per square inch. |
