In this study, the technoeconomic feasibility of bioenergy production from sawdust under four different case scenarios is simulated and compared. These include: (1) heat electricity generation raw sawdust; (2) pellet (3) (4) integrated biorefinery approach for simultaneous manufacturing multiple products (steam-exploded torrefied pellets) co-products (furfural, hydroxy methyl furfural (HMF), ac...

Some new pyrimido[1,2-a]benzimidazole derivatives were synthesized by reacting 2-amino benzimidazole and chalcones in n-butanol at reflux temperature. In our present study we have used various heterocyclic chalcones derived from furfural and substituted acetophenones. All synthesized compounds were characterized by IR, 1 H NMR and Mass spectroscopy. All synthesized compounds were screened for t...

We have constructed and applied an algorithm to simulate the behavior of zeolite frameworks during liquid adsorption. We applied this approach to compute the adsorption isotherms of furfural-water and hydroxymethyl furfural (HMF)-water mixtures adsorbing in silicalite zeolite at 300 K for comparison with experimental data. We modeled these adsorption processes under two different statistical me...

Furfural is produced by dehydration process when strong acids react with pentoses and formation of furfural occurs. It is used as a solvent for extracting mineral oils in many industrial branches and can also be found in orange juice or in brandy. Furfural is not toxic, but its oxidative by-product, pyromucic acid that is conjugated to glycine in the liver and excreted mostly in urine, has harm...

in this study the effects of autoclave, microwave and ultrasonic pretreatments with or withoutacid addition were investigated on the amount of glucose, soluble and insoluble lignin, furfural, yeast viabilityand bioethanol. the findings showed that autoclave-acid impregnated sample, has the highest glucose releasefrom lignocellulose materials (14.61 and 14.95 g/l for solvent exposed and untreate...

BACKGROUND Pretreatment of lignocellulosic biomass generates a number of undesired degradation products that can inhibit microbial metabolism. Two of these compounds, the furan aldehydes 5-hydroxymethylfurfural (HMF) and 2-furaldehyde (furfural), have been shown to be an impediment for viable ethanol production. In the present study, HMF and furfural were pulse-added during either the glucose o...
