Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

The aim of this paper is to develop a strategic plan for selecting the best options for the supply of raw material to feed paper producing plants. The decision-making is examined within the framework of benefits, opportunities, costs, and risks (BOCR). A hierarchy is used to prioritize the BOCR, using the Analytic Hierarchy Process (AHP) ratings approach. A control hierarchy is then created and...

Pectin lyase and polygalacturonase production by newly isolated Penicillium viridicatum strain Rfc3 was carried out by means of solid state fermentation using orange bagasse, corn tegument, wheat bran and mango and banana peels as carbon sources. The maximal activity value of polygalacturonase (Pg) (30U.g) was obtained using wheat bran as carbon source while maximal pectin lyase (Pl) (2000 U.g)...

The present study investigates fluid mechanical properties of cellulosic feedstocks relevant to flow through (FT) pretreatment for biological conversion of cellulosic biomass. The results inform identifying conditions for which FT pretreatment can be implemented in a practical context. Measurements of pressure drop across packed beds, viscous compaction and water absorption are reported for mil...

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand-alone second generation ethanol production process; however, bagasse is used as fuel to supply the energy demand of the first generation process, so the amoun...
