Pilot test results of post-combustion CO2 capture using solid sorbents

CO2 Adsorption: Experimental Investigation and CFD Reactor Model Validation

“…Pilot studies using coupled fluidized beds reported a number of operational difficulties that were thought to be associated with desorption kinetics [22]. Unfortunately, fluid bed desorption studies have been limited to a very few tests over a narrow range of temperatures, CO 2 compositions, and levels of conversion [28].…”

“…There are four main categories of these technologies: precombustion, postcombustion, oxy-fuel combustion, and chemical looping [5].

“…Fluidized bed reactors have been used to evaluate adsorption and regeneration using these promising polyamine sorbents [22,24,28]. Pilot studies using coupled fluidized beds reported a number of operational difficulties that were thought to be associated with desorption kinetics [22].…”

“…An overview of the literature [12][13][14][15][16][17][18][19][20][21][22][23][24] and the various sorbent reactor configurations is presented in Table 1. Samanta et al [25] and Choi et al [26] provide comprehensive reviews of sorbent processes employing temperature swing, pressure swing, or vacuum swing to regenerate the adsorbate, referred to as PSA, TSA, and VSA concepts, respectively.…”

“…Samanta et al [25] and Choi et al [26] provide comprehensive reviews of sorbent processes employing temperature swing, pressure swing, or vacuum swing to regenerate the adsorbate, referred to as PSA, TSA, and VSA concepts, respectively. The TSA concepts have gained favor recently because the polyamine impregnated sorbents which have strong temperature dependence in the temperature range of interest can be made with high CO 2 capacity [17][18][19][20][21][22][23][24].…”
