Optimisation of pressed pericarp fibre delignification for glucose recovery using response surface methodology
In this study, pressed pericarp fibres (PPFs) were subjected to chemical pretreatment for bioconversion of lignocellulosic biomass to fermentable sugars. The effectiveness and comparison between pretreatments using acid (HCl) and alkaline (NaOH) to reduce the lignin content was studied. Alkali pretreatment showed better lignin removal than acid pretreatment. Subsequent experiments were then ...

Comparison of response surface methodology and artificial neural network for optimum levulinic acid production from glucose, empty fruit bunch and kenaf
Levulinic acid (LA) is one of the versatile chemicals that can be produced from lignocellulosic biomass. In this study, response surface methodology (RSM) and artificial neural network (ANN) were applied to optimise LA yield from glucose, empty fruit bunch (EFB) and kenaf. The effect of process variables namely reaction temperature, reaction time and acid concentration on LA production was ...

Production and characterization of lignocellulosic biomass-derived activated carbon
The goal of this work is to establish the technical feasibility of producing activated carbon from pulp mill sludges. KOH chemical activation of four lignocellulosic biomass materials, two sludges from pulp mills, one sludge for a linerboard mill, and cow manure, were investigated experimentally, with a focus on the effects of KOH/biomass ratio (1/1, 1.5/1 and 2/1), activation temperature ...

Anaerobic digestion of sunflower oil cake: a current overview
Due to the chemical and physical structure of a lignocellulosic biomass, its anaerobic digestion (AD) is a slow and difficult process. In this paper, the results obtained from a batch biochemical methane potential (BMP) test and fed-batch mesophilic AD assays of sunflower oil cake (SuOC) are presented. Taking into account the low digestibility shown during one-stage experiments the methane ...

Genetic improvement of Sorghum as a biofuel feedstock: II. QTL for stem and leaf structural carbohydrates
Digestion and fermentation of lignocellulosic biomass (i.e., structural carbohydrates) are predicted to deliver higher yields of energy per hectare than sugar and starch (nonstructural carbohydrates), yet little research on genetic variation in crop feedstock biomass traits has been conducted. We investigated the genetic basis of leaf and stem biomass yield and composition in a population derived ...

Unconventional Pretreatment of Lignocellulose with Low-Temperature Plasma
Abstract Lignocellulose represents a potential supply of sustainable feedstock for the production of biofuels and chemicals. There is, however, an important cost and efficiency challenge associated with the conversion of such lignocellulosics. Because its structure is complex and not prone to undergo chemical reactions very easily, chemical and mechanical pretreatments are usually necessary to be ...

Opportunities and challenges of transitioning to sustainable next-generation transportation biofuels
A growing desire to reduce petroleum dependence and an increasing awareness that first-generation biofuels are unlikely to provide sustainable alternatives have spurred interest in next-generation biofuels. High production costs have been central in preventing their commercial viability thus far, yet other potential obstacles remain including feedstock availability, farmer adoption of biomass ...
