“…Up to date, several CO2 separation technologies have been reported, e.g. pressure swing adsorption (PSA) [3][4][5], physical or chemical solvent scrubbing [6][7][8][9][10], and membrane separation [11][12][13][14]. In the PSA process, zeolites are good candidate adsorbents but their hydrophilicity has limited their application due to the presence of water vapour which reduces the available active surface area.…”

“…In 2009, Albo et al first applied ILs into a membrane contactor and developed a “zero solvent emission” membrane absorption process based on 1-ethyl-3-methylimidazolium ethylsulfate [Emim][EtSO 4 ] and commercially available PP membrane for postcombustion CO 2 capture . Afterward, more IL-based absorbents were studied in membrane absorption processes for CO 2 capture, such as 1-ethyl-3-methylimidazolium acetate [Emim][Ac], 1-butyl-3-methyl-imidazolium tetrafluoroborate ([Bmim][BF 4 ]), 1-(3-aminopropyl)-3-methyl-imidazolium tetrafluoroborate ([apmim][BF 4 ]), and 1-butyl-3-methylimidazolium dicyanamide [Bmim][DCA] . Sirkar et al studied the possibility of using ILs in a membrane contactor for precombustion CO 2 capture at elevated temperature and pressures.…”

In the present work, membrane contactors using both porous and nonporous polymeric hollow fiber membranes with ionic liquids as absorbent were developed for precombustion CO2 capture at elevated temperature and pressures. 1-Butyl-3-methylimidazolium tricyanomethanide [Bmim][TCM] was selected as the ILs absorbent. The compatibility and stability of six different polymeric membranes were evaluated, while the porous PTFE membrane and nonporous Teflon-PP composite membrane were considered to be the most suitable membranes for this application. Both membrane configurations were tested and showed comparable separation performances: CO2 flux values of 4.86 × 10–4 and 4.75 × 10–4 mol m–2 s–1 were obtained for the porous PTFE and nonporous Teflon-PP membrane contactor at 20 bar with a gas flow rate of 200 mL min–1, respectively. The Teflon-PP composite membrane exhibited better stability as compared to the porous PTFE membrane in a 14 day test.

“…39 The main reason for these lower values is the presence of CO 2 that does not contribute to the heating value but, on the contrary, it absorbs energy to be heated. Therefore, it would be convenient to eliminate CO 2 from the gas stream, which can be done either by membranes 45 or by absorption processes. 46 The gas with the highest HHV is obtained at 700 °C but, from an industrial point of view, the most worthwhile gases would be those obtained from 700 to 900 °C, because of their high content of hydrogen, CO, and methane.…”

Woody biomass waste (Pinus radiata) has been pyrolyzed in a laboratory-scale continuous pyrolysis plant, formed by two reactors connected in series: one continuous auger reactor, where the pyrolysis process is performed, and a tubular reactor for vapors upgrading, where the thermal treatment of the pyrolysis vapors occurs to promote further cracking. The pyrolysis reactor has four different heating zones that allows programming different temperature profiles. An extensive and detailed thermal study has been performed using temperatures covering the range from 300 °C to 900 °C in regimes of scaling temperature profiles and isothermal profiles. Both the peak temperature and the heating rate affect the pyrolysis fraction yields, as well as products composition. Higher temperatures result in higher gas yield and lower solid and liquid yields. Increasing the temperature also increases the fixed and elemental carbon contents of the charcoal obtained, and decreases its volatile matter and the hydrogen and oxygen contents. Concerning gas fraction, the share of CO and hydrogen rises with the temperature. The increase of temperature gives rise to heavier liquids with more polycyclic compounds and less monocyclic compounds. The changes in the composition of the charcoal and gas products are more prominent between 300 °C and 700 °C. Compared to nonisothermal experiments, isothermal experiments enhance the production of gases, to the detriment of solid and liquids, but do not affect product composition.
