摘要
The effects of reaction time,reaction temperature and acid concentration on xylose concentration in coconut shell hydrolysate were investigated.The acid hydrolysis mechanism for coconut shell was discussed.As a homogeneous irreversible series reactions system,first-order reaction rate models for coconut shell acid hydrolysis were established.The activation energy,kinetic coefficient for xylooligosaccharides hydrolysis and kinetic coefficient for xylose decomposition were estimated.According to the rate equations,the favorable acid hydrolysis conditions were predicted,the drawn conclusions can be used to industrial production.
