ABSTRACTLignonocellulosic materials are kinds of nonfossil resources which have high potential forproduction of value added products that can be attend as an alternative for fossil energyresources Sugarcane bagasse is a major example of these materials Many works havebeen done due to production of alone products like sugars glucose xylose and furfural acetic acid bioethanol and but don t encourage successful results because ofover costs of process Using maximum potential for production of variety products is oneway for solution of this problem Attempts in this thesis focus on dilute acid hydrolysis ofsugarcane bagasse for production of furfural and glucose in pilot scale For this reason atwo stages process was designed in which in first stage furfural and in the other glucosehas being produced Reducing numbers of tests evaluation of optimum conditions anddetermination of relative importance of dependent factors taguchi method has been used Respectively the factors for first and second stages are pressure of reactor concentration ofacid and duration of reaction and pressure and duration The levels are 6 8 10 bar 1 4 5 and 120 240 360min and 14 20 26 bar and 4 7 10 min for first and secondstages respectively In whole tests of second stage the concentration was 0 5 For wholeprocess the proposed condition for first stage is 8bar 1 120min and 20bar 0 5 7minfor second stage Isfahan University of Technology Department of Industrial Engineering Systems Conversion of sugarcane bagasse to furfural and glucose A Thesis Submitted in partial fulfillment of the requirements For the degree of Master of Science
