Effect of chemical steeping on yields of glucose and xylose from dilute acid hydrolysis of extract from oil palm trunk

The effectiveness of chemical steeping was examined as a novel pretreatment prior to hydrolysis influence the extractable yield glucose and xylose from oil palm trunk (OPT). parameters were 0.2% sodium metabisulphite (w/v), 0.5% lactic acid (v/v), 26 ± 2 °C, 1 h, followed by dilute (2%, 4%, 6% sulphuric (v/v); 115 120 130 °C; 15 min, 30 60 min). For comparison, extracted untreated OPT also examined. Thermal analysis showed that successfully degraded lignocellulose OPT. total improved, approximately 2.5% 28.8% higher than non-pretreated fines. RSM °C x 50 min 2% predicted optimum for extraction through chemically treated OPT, process. Analysis variance significant model terms yield. In conclusion, successful increase
