dc.description | Several physical and chemical pre-treatments were attempted to maximize the production of xylose and glucose from the hydrolysis and saccharification of hemicellulose and cellulose from oil palm press fibre. Bleached (holocellulose, PI), alkaline treated (PII) and untreated oil palm press fibre (PIII) of different sizes "0.3 mm, 0.3 - 0.4 mm and0.4 mm) were first pre-hydrolysed with H2SO4 to produce xylose. All the treatments showed that the maximum yield of xylose was obtained from fibre of0.4 mm, and the lowest from fibre of 0.3 mm. The taller result is believed to be due to residual kernel, shell and other impurities present from the grinding. At the optimum size of0.4 mm, sample PII gave the highest yield of xylose (67.8 g litre -1) and the lowest yield was from PIII (29.2 g litre -1) while PI gave 44.5 g litre -1. The percentages of conversion of dry weight of oil palm press fibre were 23.9. | |
