Abstract (en)
[origin: WO2018104257A1] The divulged invention concerns a process for the removal of arsenic oxides inprocessexhaust gases, comprising the step of passing the exhaust gases through a supported ionic liquid phase bed,characterized in that the ionic liquid comprises one or more cations from the list consisting of substituted phosphonium, ammonium, imidazolium, pyrrolidinium, and pyridinium, and one or more anions from the list consisting of chloride, bromide, and carboxylate. Compared toa bed of active carbon, theionic liquid soaked active carbon bed according to the invention allows for an estimated doubling of thearsenic adsorptioncapacity of the bed, while also considerably enhancingthe kineticsofadsorption.
