Abstract

The abundant coffee husk residue in Vietnam could become a potential feedstock for gasification with the help of a complete engineering profile established. This study investigated the coffee husk characteristics and its thermal behaviors during gasification. high volatile matter of 70.8 % and a high ash content of 9.2 % were recorded for coffee husk. The engineering properties of the biomass were determined by ASTM methods, while the thermal behavior was determined by a Macro-TGA system. The higher heating value was 18.6 MJkg^-1, which is comparable with common woody biomass. The degradation of coffee husk began at 245^oC and achieved the maximum weight loss rate (R_max = 0.4%^oC^-1) at 310^oC. Coffee husk char gasification kinetics under various atmospheres relevant to industrial processes were quantified. Database and results from this study would provide useful information for the design or modeling of an efficient coffee husk gasifier.
