“…In the past decades, EOP process has been successfully and extensively applied to deconstruction and fractionation of various lignocellulosic biomass, for example, switchgrass (Hu et al, 2012), lodgepole pine (Pan et al, 2007), Buddleja davidii (Hallac et al, 2010), birch (Wen et al, 2013a), bamboo (Bai et al, 2013), eucalyptus (Wen et al, 2013b) and wheat straw (Huijgen et al, 2014). The efficiency of converting EOP pretreated switchgrass residue into glucose is up to 95% (Hu et al, 2012).…”

“…As a general rule, the increase in temperature by 1 °C can accelerate the breathing of the mass of grains by 2 to 3 times up to a certain limit, until breathing ceases at very high temperatures, as a result of the destructive effects of high temperatures on enzymes, causing greater structural damage on grains (FORTI et al, 2010;HUIJGEN et al, 2014).…”

ABSTRACT:The aim of the present research was to evaluate the effects of drying air temperature and storage conditions used in Brazil on the quality of corn grains (Zea mays L.) for ethanol production. The experiment was set up in a completely randomized design in a (3x2x2) factorial arrangement (drying air temperatures of 80, 100 and 120 ºC vs. ambient storage conditions of 23 ºC / 60% RH and cooled to 10 ºC / 40% RH vs. storage time of zero and six months). The corn grains were harvested with a water content of 18.0% (w.b.). Then, they were dried in a convection/forced-air oven at different temperatures, until water content reached 12% (w.b.). After that, the grains were stored. It was concluded that the increase in drying air temperature reduced lipid content and starch percentage, decreasing ethanol yield to 38.74 L ton -1 of grains. Storage under refrigeration at 10 °C was favorable for the maintenance of lipid levels (+2%), starch percentage (6%) and ethanol yield (33 L ton -1 of grains). Thus, considering production conditions and weather in Brazil, grains should be dried at air temperatures up to 80 °C, and storage must be performed under refrigerated air up to 10 °C for quality assurance of maize grains in the dry season and, therefore, increased ethanol production in the industry.

“…The lignin-based adhesives may be proposed as possible environmentally friendly and safe alternatives to phenol-formaldehyde resins [20][21][22][23][24]. Also, as furfural is a known crosslinking agent for lignin [25][26][27], lignin and furfural may be considered to replace phenol and formaldehyde, respectively, in the lignin-furfural resin systems [28]. An important advantage of using furfural is its renewable nature, underscored by its selection into the list of top ten designed products of biorefineries [29].…”

Toward Complete Utilization of Miscanthus in a Hot-Water Extraction-Based Biorefinery

et al. 2017

Miscanthus (Miscanthus sp. Family: Poaceae) was hot-water extracted (two h, at 160 • C) at three scales: laboratory (Parr reactor, 300 cm 3 ), intermediate (M/K digester, 4000 cm 3 ), and pilot (65 ft 3 -digester, 1.841 × 10 6 cm 3 ). Hot-water extracted miscanthus, hydrolyzate, and lignin recovered from hydrolyzate were characterized and evaluated for potential uses aiming at complete utilization of miscanthus. Effects of scale-up on digester yield, removal of hemicelluloses, deashing, delignification degree, lignin recovery and purity, and cellulose retention were studied. The scale-dependent results demonstrated that before implementation, hot-water extraction (HWE) should be evaluated on a scale larger than a laboratory scale. The production of energy-enriched fuel pellets from hot-water extracted miscanthus, especially in combination with recovered lignin is recommended, as energy of combustion increased gradually from native to hot-water extracted miscanthus to recovered lignin. The native and pilot-scale hot-water extracted miscanthus samples were also subjected to enzymatic hydrolysis using a cellulase-hemicellulase cocktail, to produce fermentable sugars. Hot-water extracted biomass released higher amount of glucose and xylose verifying benefits of HWE as an effective pretreatment for xylan-rich lignocellulosics. The recovered lignin was used to prepare a formaldehyde-free alternative to phenol-formaldehyde resins and as an antioxidant. Promising results were obtained for these lignin valorization pathways.
