Characterizing the 2D single atom solutions to capture CO2 by the digital twin model

Abstract

The digital twin model is developed to characterize the CO2 capture by the Cu and B 2D single atom solution (2DSAS). The key digital functions distributions f[], g[] and h[] characterize the physical 2DSAS system with the digital code 1 and 0. The thermoelectrical effect of the 2DSAS is analyzed. The digital code combinations of Cu atoms sorting from 1111 to 11,111 with B atoms sorting from 00 to 000 were identified as more suitable for CO2 capture. The effects of velocity difference of Cu and B atoms, temperature and CO2 loading were discussed. CO2 desorption efficiency was increased by an average 4.2 % and the energy consumption of desorption was reduced by 35.4 % at h[] of 3.5 × 10-6 m/s to 5 × 10-6 m/s. The 2DSAS of Cu and C, Cu and N and Cu and Si were suggested for CO2 capture.
