“…stated that ∼10% of lignin derived from wheat straw underwent degradation in TFA and gave water soluble fractions. Similar results were reported by Dong et al . Other researchers who used TFA for the electrospinning of lignocellulosic fibers report that the dissolution of lignin in TFA includes the cleavage of some covalent bonds and the disruption of the 3D network.…”

“…However, the behavior of lignin in TFA is rather ambiguous. TFA has been proposed as a solvent for the treatment and fractionation of plant biomass in order to separate and recover various useful components (cellulose, lignin, non‐cellulosic polysaccharides) . In this context, Morrison and Steward reported that most of the lignin of oat straw is insoluble to TFA, with Poirier et al .…”

Utilizing inexpensive biorenewable and waste raw materials for the production of carbon nanofibers can pave the way for lowering their manufacturing cost. In this research, lignin is combined with recycled poly(ethylene terephthalate) (PET) to fabricate precursor fibers via electrospinning. The process is optimized using the Design of Experiments statistical methodology and fibers with minimum average diameter equal to 191 6 60 nm are prepared. Investigation with Attenuated Total Reflection -Fourier Transform Infrared Spectroscopy reveals the lignin structural changes induced by the solvent (trifluoroacetic acid), which is used for the preparation of homogeneous solutions of lignin and PET in various concentrations, while it gives an indication of the blending of the two electrospun polymers. The good miscibility between lignin and PET is also confirmed with Differential Scanning Calorimetry. The subsequent carbonization of the precursor fibrous mats results in a fibrous carbon structure with average fiber diameters similar to those of the precursor fibers. The successful transformation into carbon nanofibers is affirmed by Energy Dispersive X-ray Spectroscopy. The Carbon content of these nanofibers amounts to 94.3%. V C 2016 Wiley Periodicals, Inc. J.

The aim of this contribution is to measure the effect of the pretreatment of lignocellulosic phytomass utilization for bioethanol production. The first step of bioethanol production from lignocellulosic phytomass is pretreatment of raw material. The next step is hydrolysis, and then the fermentation of sugars follows. The physical (grinding, breaking) and chemical (ozonization) processes were used as pretreatment. Ozone was applied to the aqueous suspension of lignocellulosic phytomass before and during the hydrolysis. Ozone pretreatment did not perform as effectively as expected. The results of study, which are focused on evaluation of reducing sugars are included in this contribution.
