New adsorbents of methanol for the intensification of methanol synthesis

Novel composite adsorbents Ca(NO3)2)/SiO2, LiBr/SiO2 and CaCl2/SiO2 have been intently designed for shifting the equilibrium of methanol synthesis by methanol removal from the reaction mixture. Testing of these composites in a lab-scale tubular flow reactor at the initial mixture composition CO/CO2/N2/H2 = 30.0/2.0/3.2/64.8, total pressure P = 2 MPa and temperature T = 473 K has shown their encouraging potential for this application. The former composite efficiently adsorbs methanol from the gaseous mixture under lab-scale operating conditions of methanol synthesis and demonstrates good thermal stability. It can be recommended for further testing.
