Summary
Lignocellulose is the most abundant renewable biomass, mainly comprising cellulose, hemicellulose, and lignin. These components can be fractionated and be further converted into different chemicals and materials, such as paper, bio-ethanol, functional sugars, furan, and phenolics. These products are important to support the development of human society. Additionally, efficient utilization of lignocellulosic biomass is an important way to achieve the carbon peaking and carbon neutrality goals. The efficiency of lignocellulose utilization highly depends on the processing and engineering techniques. The cutting-edge research has been focused on clean production and low energy consumption during lignocellulose processing for the sustainable development industry. And more intense efforts should be made to develop environmental-friendly techniques for lignocellulose valorization into valuable products as alternatives to petroleum-based products.
This Special Issue "Processing and engineering of lignocellulose utilization" mainly covers the research on the application of fundamental sciences of lignocellulose utilization, and the related technologies and engineering for the goal of low-carbon circular economy.
The scope of interests includes the following topics:
1) Pretreatment of lignocellulose
2) Process of lignocellulose into pulp and papermaking
3) Catalytic conversion of cellulose, hemicellulose, and lignin into bio-based chemicals
4) Lignocellulose biorefinery
5) Fibers protection
6) Low carbon economy sustainability basing on lignocellulose processing

Process and Engineering of Lignocellulose Utilization)
Abstract The effect of lignin structural units on enzymatic hydrolysis of lignocellulosic biomass was investigated, especially the inhibitory role of lignin in non-productive adsorption with enzymes. Milled wood lignin (MWL) was isolated from different hardwoods of poplar, eucalyptus and acacia. The isolated lignin samples were characterized by elemental analysis, gel permeation chromatography, nitrobenzene oxidation and fourier infrared spectroscopy. The mechanism of lignin structural units on enzymatic hydrolysis of cellulose was studied by quartz crystal microbalance (QCM). The results showed that different structural units of lignin had different adsorption capacity for enzymes. The results of nitrobenzene oxidation indicated that the S/G ratio…

Process and Engineering of Lignocellulose Utilization)
Abstract Ferulic acid (FA) and
p-coumaric acid (
pCA) in bagasse, wheat straw, corn straw, and corncob were extracted by
alkaline hydrolysis and characterized by gas chromatography (GC) and gas chromatography-mass spectrometry
(GC-MS). It was found that the FA and most of the
pCA in gramineous biomass could be dissociated and released
after being treated with 1 M NaOH at 100°C for 4 h. The yields of
pCA/FA in bagasse, wheat straw, corn straw,
and corncob determined by GC-FID are 39.8/11.5, 13.7/11.0, 28.0/11.0, and 35.1/14.5 mg/g, respectively. The raw
materials and the treated solid residues were characterized by gel-state 2D Heteronuclear Single…
