Solar-energy-driven conversion of biomass to bioethanol: a sustainable approach

Abstract

This review discusses the current methodologies and recent developments for bioethanol production from biomass. We demonstrate the future aspects of bioethanol production in solar reactors, and strategies to improve process yields as well as the prospects of using a solar reactor to produce other valuable chemicals.

Evaluating the Role of Water as a Cosolvent and an Antisolvent in [HSO4]-Based Protic Ionic Liquid Pretreatment

“…The cellulose pulps were used in their “wet” state (i.e., without air drying and moisture content 89–90 wt %) to avoid the hornification effect that can cause the collapse of the cellulose pores and hinder the hydrolysis process . Glucose yield is a valuable indicator of the performance of the process, as glucose can be further fermented to biofuels or chemicals (e.g., bioethanol, lactic acid) or chemically transformed to produce other value-added bio-based chemicals. − Glucose yields for the cellulose pulps of Miscanthus were largely unaffected by the change in the [DMBA]­[HSO 4 ]/water ratios, with a relatively high glucose yield of 72% on average. On the other hand, glucose yields from pine wood and treated timber pulps were the highest between 10 and 20 wt % water (an average of 74% relative to the theoretical maximum) with a significant drop in the glucose yield at higher water concentrations to 30 and 20% glucose yields, respectively.…”

Polymeric membranes through self-initiation and self-polymerization for high-performance bioethanol pervaporation

“…5 From a life cycle assessment perspective, bioethanol produced from cellulose and sugarcane generates nine times more energy than the fossil energy consumed. 6 In response to the growing energy crisis and environmental pollution, governments around the world have begun to focus on the development of novel renewable fuels. 7 For instance, China plans to endeavor to scale up the production of cellulosic ethanol by 2025.…”

Palladium Nanoparticles Supported on B‐Doped Carbon Nanocage as Electrocatalyst toward Ethanol Oxidation Reaction

“…[1] Direct ethanol fuel cells (DEFCs) serving as classical fuel cells are potential power supply for mobile phones, automobile owing to their superior theoretical power density, inexpensive alcohol fuel, non-toxic to the environment, and rapid start-up under low temperaturez. [2][3][4][5][6][7] The high cost, sluggish kinetics and limited reserve of platinum based electrocatalysts are the main hinder for the development and businesslike applications of DAFCs. [8][9] Therefore, the development of other novel catalysts with high electrocatalytic activity and stability for ethanol oxidation reaction (EOR) has aroused sustained attentions.…”
