WhatsApp: +86 18838072829Introduction. Nowadays, coal gasification technology is being widely developed to keep up with the soaring energy demand [1], [2]. Partial replacement of H 2 O by CO 2 to realize the gasification of coal with H 2 O/CO 2 mixtures (cogasification) is an important approach that can allow for green, lowcarbon, and sustainable development [3]. Moreover, low temperature gasification should also be ...
