The total XOS yield with optimum ozone dose of 3% (OAAH-3) was found to be 8.9% (w/w biomass) at 110 degrees C in comparison to 7.96% at 170 degrees C by autohydrolysis (AH) alone. Although, there was no significant difference in oligomeric composition (DP 2-6), significant decrease in degradation products namely furfural (2.78-fold), HMF (3.15-fold), acrylamide (nil) and acetic acid (1.06-fold), was observed with OAAH-3 as a pretreatment option. There was 1-fold higher xylan to XOS conversion and OAAH-hydrolysate had higher DPPH radical scavenging activity than AH. PCA plots indicated clear enhancement in XOS production and lower generation of inhibitors with decrease in treatment temperature. Results of the study therefore suggest OAAH can be an effective pretreatment option that can further be integrated with downstream processing for concentration and purification of XOS.10aAdvanced oxidation10aAgro-industry waste10ahydrothermal treatment10aOzonolysis10aXylooligosaccharide1 aSonkar, Rutuja, Murlidhar1 aGade, Pravin, Savata1 aBokade, Vijay1 aMudliar, Sandeep, N.1 aBhatt, Praveena  uhttps://library.ncl.res.in/content/ozone-assisted-autohydrolysis-wheat-bran-enhances-xylooligosaccharide-production-low02090nas a2200253   4500008004100000022001400041245015100055210006900206260000900275300001600284490000700300520117500307100002501482700002201507700002701529700002001556700002101576700002301597700001801620700002401638700001801662700002501680856013101705       2024                        eng d  a0887-062400aOne-pot production of liquid hydrocarbons by catalytic hydrodeoxygenation of lignocellulosic biomass using nickel loaded on zeolite-based supports0 aOnepot production of liquid hydrocarbons by catalytic hydrodeoxy  cJUL   a13029-130380 v383 a<p>
	The synthesis of liquid hydrocarbons from lignocellulosic biomass has been achieved with notable success. However, these technologies often require multistep approaches and are energy intensive. Thus, there is a considerable economic and environmental benefit of process intensification by the synthesis of liquid hydrocarbons in a one-pot process. For the first time, we report direct conversion of raw poplar into liquid alkanes and aromatics (carbon yield of 15.6 +/- 0.6 wt %) with high selectivity toward C-7-C15 cycloalkanes (7.8 +/- 0.1 wt %) and low level of oxygenated compounds (&lt;2.0 wt %) at 270 degrees C and 3 MPa initial H(2 )pressure for 6 h using 10% Ni/H-beta zeolite as a catalyst and cyclohexane as a solvent. The effect of temperature (250-270 degrees C), Ni loading (0-10%), and type of zeolite support (H-beta, ZSM-5, and USY) on process performance was also investigated. In addition, the 10% Ni/H-beta catalyst showed recyclability over two reactions, with a 17.6% decrease in liquid hydrocarbon yield after the first reaction. This approach has the potential to simplify the synthesis of liquid fuels from lignocellulosic biomass.</p>
