“…From these data, we can conclude that 1 can be used to separate H 2 /CO 2 and O 2 /N 2 , and 1a can be used to separate CH 4 /H 2 . Separation of CO 2 and H 2 is important in water–gas shift and steam-reforming hydrogen production. , It can be inferred that both 1 and 1a show much higher O 2 and CO 2 adsorption capacities than those of H 2 , N 2 , and CH 4 , which can be attributed to the strong interactions with the groups in porous structures. Moreover, different hydrophobic and hydrophilic channels could influence the O 2 and CO 2 adsorption capacities, which cause 1a with hydrophilic channels (5.97 Å) showing higher adsorption amounts of O 2 and CO 2 than those of 1 with the hydrophobic channels (4.63 Å) …”

Selective liquid and gas adsorptions are important for environmental control and industrial processes. Here, unique porous lanthanide−organic frameworks of [Ln 2 (1,3-pdta) 2 (H 2 O) 2 ] n 2n− {Ln = La (1), Ce (2), Pr (3), and Nd (4), 1,3-pdta = CH 2 [CH 2 N-(CH 2 CO 2 H) 2 ] 2 } are template-synthesized by 1,2-ethylenediamine and fully characterized, which possess hydrophobic and hydrophilic open channels simultaneously. The skeletons are stable up to 200 °C. Obvious downfield shifts have been observed for 1,2-ethylenediamine in the confined channel with solid-state 13 C NMR measurement. The ammonium salt is directly used for the removal of 1,2-ethylenediamine in water. Its saturated adsorption capacity is reached in <1 min and can be regenerated easily with a similar uptake capacity. Moreover, the materials can also selectively adsorb O 2 , CH 4 , and CO 2 , respectively, which is useful for CO 2 /CH 4 , CO 2 /H 2 , and O 2 /N 2 separation. The combined hydrophobic and hydrophilic open channels of the lanthanides make them promising functional materials for the elimination of 1,2-ethylenediamine and gas separations.

“…The estimated steam content was 36% at the raw gas inlet, corresponding to a steam-to-carbon ratio of 1.75, as calculated from the model outputs. The steam content in the gas feed to the burner was calculated by using both gasifier data (moisture content of biomass feedstock, steam flow to gasifier, and the online gas analysis at gasifier outlet) and the water gas shift equilibrium 40 at the actual gas temperature of the gasifier outlet.…”

There is global interest in utilization of biomass energy through thermochemical processes such as gasification. The crucial step in many gasification processes is the upgrading of the produced gas, removing for example problematic components, such as tar, preferably with a flexible solution that adapts to several feedstock compositions, gasification technologies, and conditions. The present work focuses on the underpinning modeling for the development of a burner for partial combustion in an autothermal tar reformer. A design and modeling study considering the effect of the burner geometry and inlet locations on flame stability was performed. The model and the constructed burner is verified and validated against experimental results, displaying a successful operation of the combustion zone, verifying and validating the developed model against specific requirements. The verified model was finally applied for an extended process window.
