Investigation of Indonesian low rank coals gasification in a fixed bed reactor with K2CO3 catalyst loading

摘要: Abstract Catalytic steam gasification is considered one of promising technologies for converting solid carbonaceous feedstocks into hydrogen-rich syngas, which an important source hydrogen various industrial sectors. The K2CO3-catalyzed low rank coals (LRCs) was conducted in a fixed bed reactor elucidating the effects gasifying temperature and catalyst loading amount on yield. Hydrogen-rich syngas can be obtained at 800 °C 10 wt% K2CO3. K2CO3 saturation point provided good reactivity catalytic three LRCs. experimental data these LRCs were well described by random pore model (RPM). RPM fitted better than 700 °C 600 °C. Reactivity index (R0.5), activation energy (Ea) reaction rate constant (k) also used to predict characteristics process. utilizing mixture as feedstock investigated displayed XC 86.22% 0.95 mol mol−1-C, indicating feasibility potential applications.
