Abstract: “In this study, the dilute acid saccarification of plant waste as a lignocellulose biomass for fermentable sugar production as a green fuel has investigated. The Influence of 3 major parameters Temperature, acid concentration and time on produced fermentable sugars has been investigated by response surface model. According to previous studies levels for pretreatment were: temperature (124, 132 and 140oC), process time (30, 40 and 50 minute and sulfuric acid concentration (1, 2, 3%). For this purpose, plant waste was gathered in November of 2015 from Torbat Heidarieh city (Razavi Khorasan, Iran). It was washed by distillated water, air dried and milled to particle size smaller than 50 micrometers and stored in sealed plastic bags at the room temperature. This prepared biomass heated in acid solution in autoclave for determined time. For determination of product filtered solution was analyzed by HPLC and results (Glucose) were modeled by a quadratic equation. Thi”
