Kenaf (Hibiscus cannabinus) is a lignocellulosic plant that is usually utilized as a fiber source for sack production. The core from kenaf fiber has not been utilized yet in Indonesia, therefore it is still considered as a waste. Hemicellulose from kenaf core can be hydrolyzed to xylose through dilute sulfuric acid hydrolysis in high temperature. Hydrolysis in this study was done by using autoclave at 121℃ and 10% (m/v) biomass: acid ratio for 15 and 45 minutes with a variation on acid concentration (2%, 4%, and 6% v/v). Xylose concentration in the hydrolyzate tends to increase with higher acid concentration and longer heating time. 6% (v/v) sulfuric acid concentration and 45 minutes of heating time produce the highest xylose concentration (20.53 gr/L) and yield (86.50%)

Coconut dregs that are commonly used for animal feed have the potential for glucose production due to high carbohydrate content. Nevertheless, no study found on understanding the properties of this biomass. Hence, the main purpose of this paper was to propose appropriate operational conditions for the dilute sulfuric acid hydrolysis of coconut dregs and to investigate the chemical and thermal properties of coconut dregs. The biomass was hydrolyzed with 1% sulfuric acid (v/v) at different residence times (30 and 60 min) and temperatures (110, 120 and 130°C). Higher glucose produced (0.29 g/L ) was obtained when the coconut dregs were hydrolyzed at temperature of 130°C and a residence time of 60 min. FTIR spectrarevealedthe degradation of the lignocelluloses chemical structure. The changes of the chemical structure of hemicelluloses and cellulose after hydrolysis obviously showed that the degradation of the polymer of carbohydrate in coconut dregs to glucose. These results of degradation of lignocelluloses compound were consistent with those from the TGA. The result from TGA analysis revealed a reduction in thermal stability of the hydrolyzed fraction compared to raw state of coconut dregs.

In this paper, through the study of reducing sugar conditions of corn straw hydrolysis under acidic condition, looking for the production of experimental conditions relatively reasonable. Mainly by dilute sulfuric acid hydrolysis of corn straw by single factor test, effects of sulfuric acid concentration, temperature, reaction time, particle size, ratio of solid to liquid five factors, effects on sugar yield of corn straw. The dilute sulfuric acid concentration 5%, ratio of solid to liquid was 1:14, when the reaction time is 140 min, particle fineness of 120 mesh, the reaction temperature is 100 °C, corn stalk sugar yield reached a maximum 20.11%.
