Abstract

The kinetics of HCl reaction with CaO was investigated over the temperature range of 148 to 400 °C. A thin film of CaO was deposited on quartz wool and used as the sorbent. The HCl concentration was maintained uniformly in the closed system with a circulating pump in order to minimize the effects of the bulk mass transfer and pore diffusion. The HCl concentration was continuously monitored in a FT-IR cell and the HCl and H2O spectra were collected automatically by GC software at 1.2 second intervals. In this way, fewer errors were introduced into the system. The results showed excellent agreement of the data with first order reaction kinetics with respect to HCl concentration. The activation energy of 7490 kJ/mol is slightly larger than reported by others and indicative of the real kinetics of HCl with CaO surfaces.
