    • This invention relates to a liquid absorbent system for capture of carbon dioxide present in gases which comprises of contacting a CO2-containing gas with an aqueous solution containing an amine salt of an amino acid of the general formula [1]. wherein Am is an amino acid backbone containing 1 to 4 carbon atoms and at least one amine group. The amino acid is reacted with an amine with at least one amine functionality and where at least one of R1, R2 and R3 is an alkyl, alkanol, or amine group. The absorbent system is the product of neutralizing stoichiometric proportions of an amino acid with an organic base, the amine; wherein excess amine could be used as promoter. This absorbent system improves carbon dioxide removal efficiency due to its higher CO2 removal ability per cycle when compared with conventional amine and absorbent from organic acid neutralized with inorganic base. It also does not exhibit solvent vaporisation loss because the absorbent is in salt form, thus its ionic nature practically does not allow solvent vapour pressure.
    • 本发明涉及用于捕获气体中存在的二氧化碳的液体吸收系统,其包括使含CO 2的气体与含有通式[1]的氨基酸的胺盐的水溶液接触。 其中Am是含有1至4个碳原子和至少一个胺基团的氨基酸主链。 氨基酸与具有至少一个胺官能团的胺反应,并且其中R 1,R 2和R 3中的至少一个是烷基,链烷醇或胺基。 吸收系统是氨基酸与有机碱中和化学计量比例的产物,胺; 其中过量的胺可用作促进剂。 与常规胺和与无机碱中和的有机酸的吸收剂相比,由于其每循环的CO 2去除能力更高,因此该吸收体系提高了二氧化碳去除效率。 由于吸收剂是盐形式,因此其也不表现出溶剂蒸发损失,因此其离子性质实际上不允许溶剂蒸气压。

    • A slurry bubble column reactor (11) arranged in use to include a slurry phase (12) and above the slurry phase (12), a gas phase (15), the reactor (11) includes a downcomer (16) secured within it. The downcomer (16) comprises an elongate tube, the tube having a lower portion (18) and an upper portion (17). The lower portion (18) has a slurry outlet in the region of the bottom of the tube while the upper portion (17) has a slurry inlet arranged to allow slurry to enter the tube and a gas outlet (21) in the region of the top of the tube. The slurry inlet comprises a series of slots (22) in the wall of the upper portion. The uppermost part of the upper portion (17) extends above the surface of the slurry phase (12) in use and is open for fluid communication with the gas phase (15) above the slurry phase (12), thereby providing the gas outlet (21), and the slots (22) in the upper portion (17) are at a position below the surface of the slurry (12) in use.
    • 浆料鼓泡塔反应器(11),其布置在使用中以包括淤浆相(12)和浆料相(12)之上,气相(15),反应器(11)包括固定在其内的降液管(16)。 降液管(16)包括细长管,该管具有下部(18)和上部(17)。 下部(18)在管的底部区域具有浆料出口,而上部(17)具有布置成允许浆料进入管的浆料入口和在该区域内的气体出口(21) 管顶。 浆料入口包括在上部壁的壁中的一系列狭槽(22)。 上部(17)的最上部在使用中在浆液相(12)的表面上方延伸,并且与浆液相(12)上方的气相(15)开放以便流体连通,由此提供气体出口 21),并且上部(17)中的槽(22)在使用中处于浆液(12)的表面下方的位置。
