The production of fuel ethanol from low-cost lignocellulosic biomass currently suffers from several limitations. One of them is the presence of inhibitors in lignocellulosic hydrolysates that are released during pre-treatment. These compounds inhibit growth and hamper the production of ethanol, thereby affecting process economics. To delineate the effects of such complex mixtures, we conducted ...

This article presents an algorithm for modelling an Adaptive Neuro Fuzzy Inference System (ANFIS) for power transformer paper conditions in order to estimate the transformer’s expected life. The dielectric characteristics, dissolved gasses, and furfural of 108 running transformers were collected, which were divided into 76 training datasets and another 32 testing datasets. The degree of polymer...

In Colombia, approximately 855 840 tons of arracacha are produced each year. The unsalable postharvest root (Arracacia xanthorriza Bancroft) is not commercialized, mainly due to mechanical damage or small and misshapen roots. this work, dry samples were characterized subjected two treatments: one using thermal hydrolysis, applying saturated steam at pressures 0,1034 MPa, 0,2068 0,4137 MPa; anot...

treatment efficiency, design factors and kinetic coefficients were studied using two pilots of activated sludge (as) and powdered activated carbon technology (pact), for treating tehran oil refinery effluent, in a duration of more than 12 months in order to evaluate the performance of each system against growth inhibitor shock loads, different concentrations of phenol and furfural (10-300 mg/l)...

partial replacement of formaldehyde with furfural in the urea-formaldehyde resin on the formaldehydeemission, physical and mechanical properties of particleboard was investigated. the modulus ofrupture (mor), modulus of elasticity (moe), internal bond (ib), water absorption (wa), thicknessswelling (ts) and formaldehyde emission (fe) of poplar particleboards made with the modifiedresins were mea...

2,5-Furandicarboxylic acid (FDCA) is a valuable compound that can be synthesized from biomass-derived hydroxymethylfurfural (HMF), and holds great potential as promising replacement for petroleum-based terephthalic in the production of polyamides, polyesters, polyurethanes used universally. However, an economical large-scale strategy HMF lignocellulosic biomass yet to established. This study ai...
