Title: Evaluation of amine-incorporated porous polymer networks (aPPNs) as sorbents for post­combustion CO2 capture

Abstract

This is the final report for the TAMU project “Evaluation of amine-incorporated porous polymer networks (aPPNs) as sorbents for post­combustion CO2 capture.” During this project, a team consisting of the Zhou group at Texas A&M University and framergy Inc. were tasked with developing a porous polymer network (PPN) based sorbent system for CO2 capture applications. The three year project was divided up into 3 individual budget periods. During budget period 1 the team develop multiple novel PPN based sorbents and began initial CO2 capture experiments. During the course of this research the team determined that two sorbents were the standout targets, PPN-150-DETA and PPN-151-DETA. During budget period 2 the team further developed these two materials, gathering data to determine their performance under both wet and dry conditions, determine their CO2 adsorption capacities, heats of adsorption, regenerative energy demands, and mechanical attrition. In addition, budget period 2 saw the development of 50 g and 250 g batches of both sorbents, while still maintaining >0.10 g/g uptake capacity under wet gas conditions. Following budget period 2 testing, the team opted to continue on with PPN-151-DETA due to its superior CO2 cycling capabilities, with a consistent uptake capacity observed over 30 cycles atmore » the lab scale. During budget period 3 the team further developed the material at scale, producing a 1 kg batch of material. Following this, the team performed multiple long-term cycling tests in the presence and absence of SO2 using a 100 mL column. During this testing the team observed that the material loses significant uptake capacity due to SO2, as well as shows some level of DETA loss, which resulted in instrument breakdown and a request for a no-cost extension. The team was able to finalize the experiment with a test using a 1.5 L column in the absence of SO2, with the final cycle uptakes being around 0.035 g/g due to the need to harshly activate the material to prevent DETA desorption.« less
