ABSORPTION OF CO, H-2 AND CH4 IN TOLUENE AND COPPER(I) TETRACHLOROALUMINATE-TOLUENE SOLUTIONS AT ELEVATED PRESSURES

Abstract:
Solubilities of the coal-gasification products CO, H-2, and CH4 in pure toluene have been measured at temperatures between 249 and 343 K and pressures up to 7 MPa. Phase equilibria of CO and copper(I) tetrachloroaluminate-toluene solutions are presented between 254 and 333 K and pressures up to 9.5 MPa. In this absorbent, reversible chemical reactions occur resulting in a formation of several bimetallic salt complexes having a high bonding capacity for CO. Solubility measurements with H-2 and CH4 in this agent show that these gases do not undergo any chemical reaction.
