Catalytic conversion of furfural towards fuel biocomponents
Introduction The climate change, the perspective of finishing oil resource and its rising prices led the world to search for an alternative ways of acquiring valuable chemicals and fuels. In recent years technologies of production the most important chemicals for chemical and automotive industries are developed, especially these which use a renewable source of biomass (biodegradable fraction of...
متن کاملAcid-catalyzed conversion of xylose, xylan and straw into furfural by microwave-assisted reaction.
Furfural is a biomass derived-chemical that can be used to replace petrochemicals. In this study, the acid-catalyzed conversion of xylose and xylan to furfural by microwave-assisted reaction was investigated at selected ranges of temperature (140-190°C), time (1-30 min), substrate concentration (1:5-1:200 solid:liquid ratio), and pH (2-0.13). We found that a temperature of 180°C, a solid:liquid...
متن کاملQuantitative Formation of Furfural from Xylose
A study has been made of various methods of distillation of solutions of furfural and of xylose with the object of increasing the 88-percent yield of furfural obtained from xylose by the present standard m ethod of distillation. Sources of error that have been considered are: Decomposition of furfural, volatilization of furfural, effect of rubber stoppers used in the distillation procedure, inc...
متن کاملConversion of D-xylose into furfural with aluminum and hafnium pillared clays as catalyst
The industrial practice used to produce furfural is the dehydration of pentoses, which is carried out using highly corrosive and contaminating mineral acid catalysts. Because of the ecological and toxicological threats of this process and the complexity of product separation associated with these substances, the development of new acid solid catalysts has expanded in recent years. The present w...
متن کاملMicrowave-Assisted Green Production of Furfural from D-xylose of Sugarcane Bagasse
D-xylose is a component of sugarcane bagasse that can be used as a renewable resource for the production of a variety of chemicals. By means of catalytic reactions in an aqueous medium, it was determined that D-xylose can efficiently be converted into furfural by the application of microwave as a green synthetic methodology. The highest yields of furfural were obtained at a HCl concentration of...
