Tiivistelmä
The purpose of this study was the initial investigation, commissioning, and familiarizing with the Micromeritic FR-100. The automated reactor system is an innovative equipment with advanced features which is utilized for screening and testing of catalyst in a faster process whereby also resources are saved.
In the literature part a process description including a demonstration of controlling the flow condition of the equipment as well as summarizing the running operation manual has been explained. Specially, the relevant applications of the reactor have been presented to under-stand the ability of the system. The GC principles, parameters, and applications in addition to an overview of demonstrated reactions are described. Finally, a summary of the Agilent 8860 2D GC-MS analyzer process which is connected to the outlet gases of the FR-100 flow reactor are interpreted.
The experimental part commissioning, modelling, preparing, and testing experiments to examine the results of the system was carried out. The running experiments were related to “Power-to-X” and carbon dioxide utilization. A flow of 125 mln/min CO2/H2 (1:3) was fed into the reactor with a present of Cu/ZnO/Al2O3 catalyst at pressures of 30 to 55 bar and temperatures of 210 °C to 270 °C. The liquid sample were analysed with Agilent 6890 GC and the gases via mass spectrometry. The highest conversion was achieved with 240 °C and 50 bar pressure wherein 3,5 mL of liquid was produced in 126 min and the liquid com-posed 56 % of methanol. Furthermore, the CO2 conversion calculated via liquid was 8 % and a high and even surpass the equilibrium percentage of 27,5 % via the MS results with those parameters. It was also found that CO2/H2 reactance slightly increased with rising temperature.
