“…Forestry residues refer to biomass not collected from logging sites, as well as biomass resulting from forest management operations. Industrial and urban residues include solid residues, sewage sludge and industrial residues [1] [6]. Sources of plant biomass, such as agriculture residues and energetic crops, are excellent alternatives for feedstocks once they present high biomass productivity, high sugar content, are easy to grow having extensive cultivation in short period of time, are tolerant to drought, to high temperatures, to floods and saline stress, as well as have low soil demands [22].…”

“…While, in softwood, the most abundant structural block is glucomannan, a polymer with a linear chain of D-mannose and D-glucose connected by β-1,4 glycosidic bonds and some branches. Some of the sugars present in hemicelluloses associate with lignin, forming carbohydrate-lignin complexes, making enzymatic cleavage of lignocellulosic residues more complicated [6] [10] [22].…”

The use of renewable sources for obtainment of chemicals, biofuels, materials and energy has become each time larger due to environmental, political and economical problems of non-renewable energies utilization. Among several products that can be obtained from lignocellulosic biomass, which is a renewable source, there is furfural, a chemical from which many other value added chemical products can be obtained. The main route for furfural production consists of an acid hydrolysis of hemicelluloses present in lignocellulosic biomass to obtain xylose, which goes through a dehydration reaction to produce furfural. Due to the presence of an aldehyde group and a conjugated system of double bounds, furfural can go through several reactions, allowing the production of a range of value added products. In this sense, this article performs a review about mechanisms of furfural production from lignocellulosic biomass, highlighting its chemical properties which enable its utilization in different industrial applications of economic interest.

med predelavo, se zaradi visoke kurilnosti bukovine običajno namenjajo pridobivanju toplotne energije, torej v energetske namene. Na tržišču se pojavljajo v obliki drv, peletov in briketov, ki kot energenti ne dosegajo visoke dodane vrednosti. Iz surovine višje kakovosti je mogoče izdelati številne polizdelke in izdelke z visoko dodano vrednostjo, kar pa terja predvsem učinkovito delovanje gozdno-lesne verige in je podrobneje predstavljeno v prispevkih Kropivšek in Čufar (2015) ter Čufar et al. (2017) in je bilo temeljiteje preučevano v sklopu CRP projekta Racionalna raba lesa listavcev s poudarkom na bukovini. Poleg mehanskih in ostalih (tudi obdelovalnih) lastnosti pa lahko s pridom izkoriščamo tudi kemijsko strukturo bukovine za pridobivanje niza tržno zanimivih spojin (Zule, 2015). S tem se odpira široko področje inovativnih rab bukovine s poudarkom na celovitejši izrabi surovine slabše kakovosti in lesnih ostankov, ob hkratnem zagotavljanju načel krožnega gospodarstva (European Commission, 2017).

“…Basically, the biomass is subjected to high temperatures (around 500°C), in the absence of oxygen, with or without the aid of catalysts, to promote the decomposition of organic compounds into three streams: bio-oil, bio-gas, and coke. Although undesired products are generated, thermal cracking can be managed to produce greater fractions of the desired products Despite the numerous research studies carried out in this area, barriers associated with the design of an industrial plant to produce exclusively this type of biofuels still hinder its economic viability (Maity, 2015). It is clear that a large investment would be needed to design new structures and create an achievable market for biofuels.…”
