Carbonisation of bagasse in a fixed bed reactor: influence of process variables on char yield and characteristics

摘要: Abstract Carbonisation experiments on samples of sugar cane bagasse were conducted in a static fixed bed reactor to determine the effect process variables such as temperature, heating rate, inert sweep gas flow rate and particle size yield composition solid product char. Experiments performed final temperatures 250–700°C with rates from 5 30°C/min nitrogen 350 cc/min. Additional tests aimed at studying different 0 700 cc/min during carbonization fractions bagasse. The results showed that carbonisation temperature was increased, char decreased. reduction rapid up 500°C slower thereafter. relatively insensitive changes size. Increasing reduced It appears presence secondary reactions which promoted formation. proximate analysis suggests carbon ash content increased temperature. obtained higher than have high is suitable renewable fuel for other applications. has potential produce environmental friendly fuels can assist reducing deforestation production charcoal.
