Gasification of Brazilian coal-chars with CO₂: effect of samples’ properties on reactivity and kinetic modeling

Gasification of Shenhua Bituminous Coal with CO2: Effect of Coal Particle Size on Kinetic Behavior and Ash Fusibility

“…In order to deal with increasing environmental problems, clean and efficient coal conversion technologies must be urgently developed. Coal gasification technology deserves attention because it is the process that produces valuable gaseous mixtures consisting primarily of H 2 and CO (syngas) with high fuel conversion efficiency [2]. Syngas can be utilized to produce liquid fuel and various kinds of chemicals.…”

“…Coal gasification contains two primary stages: (1) pyrolysis of raw coal and (2) gasification of remaining coal char [3]. Char gasification is usually a slower process than pyrolysis and is the rate-limiting step of the whole process; therefore, the knowledge of gasification kinetics is vital for designing gasification reactors [2]. Thus, gasification kinetic analyses are the starting point for the design, optimization, and operation of gasifiers [3,4].…”

“…Thus, gasification kinetic analyses are the starting point for the design, optimization, and operation of gasifiers [3,4]. The most frequently utilized gasification agents include O 2 , air, H 2 O, and CO 2 , among which steam is the most widely used [2]. Unlike CO 2 , water is resource-limited and energy-intensive.…”
