✦ Synopsis

Ca(OH)z during the latter part of gasification. Fixed carbon conversion at 850°C without calcium is 65% after 2 h, whereas the catalysts achieve complete gasification within 1 h. The apparent activation energy is almost unchanged by calcium addition and the main product is Hz. Calcium increases Hz and COz, but it decreases CO, which leads to much higher Hz/ CO ratio in the presence of calcium. Thus, Ca(OH)s and CaCOs promote shift reaction of CO formed with steam and are suitable for the production of Hz-rich gas from petroleum coke.
