It is shown that copolymers of polyethylene- and polypropyleneglycolmaleates (p-EGM and p‑PGM) with acrylic acid (AA) can be used as matrices for the preparation of effective metal-polymer complexes for hydrogenation of organic compounds. Electron microscope and dynamic scattering are used to determine the average nanoparticle size of 112 nm; the nanoparticles are spheres with a uniform distribution...
Results are presented from a comparative study of CO2 hydrogenation under gas-phase and supercritical conditions for CO2 in the presence of 15% Fe/SiO2 catalyst. The reaction is studied in the temperature range of 300–500°C at atmospheric pressure under gas-phase conditions and at a pressure of 95 atm under supercritical conditions at an Н2 : СО2 molar ratio of 2 : 1. It is found that the process...
