Abstract

Water washing of raw samples was carried out to determine its effect on the acid hydrolysis process used for producing sugars from EFB. The results showed that sugar yield obtained from washed EFB is more reflective of the actual conversion rate compared to unwashed EFB. Sugar yields were 24.6 % for washed samples and 13 % for unwashed samples. Also deviations in the various measurements made were significantly higher for unwashed EFB. However this could be reduced by washing. A contour plot of parameters was done to determine the optimal conditions for the acid hydrolysis process. It was found that the highest sugar yield obtainable is when the EFB particle size is 0.250 mm and the hydrolysis time is 4 hours.

洗涤和原料粒度对油棕空果串酸水解研究的影响

对原料样品进行水洗，以确定其对EFB酸水解制糖过程的影响。结果表明，与未洗涤的EFB相比，洗涤后的EFB产糖率更能反映实际转化率。水洗样品的糖收率为24.6%，未水洗样品的糖收率为13%。此外，对未洗涤的EFB进行的各种测量的偏差明显更高。然而，这可以通过洗涤来减少。通过等高线图确定了酸水解工艺的最佳条件。结果表明，当EFB粒径为0.250 mm，水解时间为4小时时，糖得率最高。
