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-catalysed conversion of saccharides into furanic aldehydes in the presence of three-dimensional mesoporous Al-TUD-1.
The one-pot acid-catalysed conversion of mono/di/polysaccharides (inulin, xylan, cellobiose, sucrose, glucose, fructose, xylose) into 2-furfuraldehyde (FUR) or 5-hydroxymethylfurfural (HMF) in the presence of aluminium-containing mesoporous TUD-1 (denoted as Al-TUD-1, Si/Al = 21), at 170 degrees C was investigated. Xylose gave 60% FUR yield after 6 h reaction; hexose-based mono/disaccharides ga...
متن کاملConversion and assimilation of furfural and 5-(hydroxymethyl)furfural by Pseudomonas putida KT2440
The sugar dehydration products, furfural and 5-(hydroxymethyl)furfural (HMF), are commonly formed during high-temperature processing of lignocellulose, most often in thermochemical pretreatment, liquefaction, or pyrolysis. Typically, these two aldehydes are considered major inhibitors in microbial conversion processes. Many microbes can convert these compounds to their less toxic, dead-end alco...
متن کاملConversion of fructose into 5-(hydroxymethyl)furfural in sulfolane.
Population growth has created an expanding gap between the supply and demand of both energy and chemicals. Nonrenewable fossil sources, such as coal, natural gas, and petroleum, are the source of nearly 86% of the world’s energy and 96% of its organic chemicals. Diminishing reserves of these sources, rising atmospheric CO2 levels, and socioeconomic concerns require a reduction of our dependence...
متن کاملTheoretical model of internal rotation in monosubstituted derivatives of furfural
The present work explores the effect of substitution in all free positions of furfural on conformational preferences of formyl group by using ab-initio calculations at the MP2/6-31G(p,d) level of theory. Theoretical modeling was made in vacuo. The selected substituents were -CH(3), NH(2), NO(2) and F groups in 3, 4, 5 and ipso carbonyl positions. Geometries of all derivatives were analyzed and ...
