摘要

本文研究了椰壳经酸水解制备木糖的反应温度、反应时间和酸浓度对水解液中木糖浓度的影响，探讨了椰壳酸水解反应的机理，建立了木聚糖降解与木糖分解的均相不可逆连串水解反应动力学模型，求出了反应活化能Ea，木糖生成与分解反应速率常数k1、k2，建立了k1 与酸浓度C和反应温度T的关系式，分析了提高k1与k1/k2比值的酸水解条件，其规律可供实现工业化生产借鉴。

Abstract

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.
