Abstract The paper pulp bagasse cellulose was pretreated under the conditions of t =5 5h, T =155��160��, P =0 6MPa,pH=4 5 The size of paper pulp bagasse cellulose was 40 mesh.The Yakult Onozuka R-10 cellulase was used in the experiments.The paper pulp bagasse cellulose enzymatic hydrolysis were carried out in tank reactor and fixed bed reactor under the conditions of T =50��,pH=4 8 The hydrolysis processes in tank reactor and fixed bed reactor were studied.The hydrolysis reducing sugar yields were inspected in the different cellulose concentrations,different stirred strong for tank reactor and different cycle liquid velocity for fixed bed reactor.The experiment results indicated that the higher bagasse concentration,the lower reducing sugar yields.The stronger the stir for tank reactor,the higher reducing sugar yields and the higher of liquid velocity for fixed bed reactor,the higher reducing sugar yields.Comparing various factors of tank and fixed bed reactor,the fixed bed reactor is considered as a better reactor for the bagasse cellulose enzymatic hydrolysis process for industry utilization.
