This study explores the potential of Zn(NH3)(CO3) for selective CO2 separation. It develops a novel highly controllable single-pot synthesis approach based on urea hydrolysis and solvothermal aging to increase the feasibility of synthesizing Zn(NH3)(CO3), determines the structure of Zn(NH3)(CO3) in detail through single-crystal X-ray diffraction and powder X-ray diffraction analyses, and performs adsorption analyses for the compound using N2, H2, and CO2 as adsorptive.
The process to produce polypropylene described herein includes contacting propylene, in a polymerization system, with one or more catalyst systems, at a temperature above 90 °C and at a pressure above 12 MPa. The polymerization advantageously takes place in a homogeneous polymerization system within a continuous polymerization reactor.
