While Fischer-Tropsch synthesis (FTS) using coal and natural gas in conventional reactors is an almost well-established technology, the production of liquid hydrocarbons from syngas obtained from biomass is in its preliminary stages of commercialization in countries like Germany. With concerns about global warming and ways of disposing of CO2 being searched for, CO2 hydrogenation using FTS to l...
This review paper presents the current state of the art on maleic acid synthesis from biomass-derived chemicals over homogeneous or heterogeneous catalysts. It is based on the most recent publications on the topic, which are discussed in details with respect to the observed catalytic performances. The recent developments and the technical drawbacks in the gas and the liquid phases are also repo...
The depletion of fossil resources makes the transition towards renewable ones more urgent. For this purpose, synthesis strategic platform-chemicals, such as 5-hydroxymethylfurfural (HMF), represents a fundamental challenge for development feasible bio-refinery. HMF perfectly deals with necessity, because it can be obtained from hexose fraction biomass. Thanks to its high reactivity, exploited m...
Bio-piezoelectric platforms with the ability of mechanical–electrical energy conversion exhibit great potential in biomedical field. In article number 2008452, Wansong Chen, Yan Zhang, Chris Bowen, and co-workers review latest development bio-piezoelectric from a broad perspective, highlighting design engineering strategies materials systematically outlining current state-of-the-art applications.
Microwave energy (MWe) is, nowadays, widely used as a clean synthesis tool to improve several chemical reactions, such as drug molecule synthesis, carbohydrate conversion and biomass pyrolysis. On the other hand, its exploitation in enzymatic reactions has only been fleetingly investigated and, hence, further study of MWe is required to reach a precise understanding of its potential in this fie...
A bio-oil-based epoxy (BOE) resin was synthesized using phenolic compounds from beechwood pyrolysis oil. These were separated crude oil by coupling two methods: fractional condensation and water extraction. The chemical structure of the BOE characterized NMR FTIR analyses. used as a curing agent bio-oil glyoxal novolac (BOG) to gradually replace bisphenol diglycidyl ether (DGEBA). thermal prope...
Biocompatible Ionic Liquids (Bio-ILs) are a new class of ILs that task-specifically designed to derive from naturally occurring compounds and/or derivatives thereof, as well molecules known for their biocompatibility (e.g., active pharmaceutical ingredients or non-toxic bioactive compounds) in terms sustainability and biocompatibility. Owing remarkable physicochemical properties can be tailor m...
Baobab (Adansonia digitata) is a promising bio-resource distributed across Africa. A variety of biofuels such as biodiesel, bioethanol, bio-oil and biogas can be prepared from feedstock derived baobab. In this vein, different parts baobab plant, for instance oil, fruit shells, seed cakes utilized biofuel synthesis. study, novozyme-435 (CAL-B) was used biocatalyst biodiesel production. Oil to co...
The biofuel mix in transport in the UK must be increased from currently exploited 3.33% to the EU target mix of 10% by 2020. Under the face of this huge challenge, the most viable way forward is to process infrastructure-compatible intermediate, such as bio-oil from fast pyrolysis of lignocellulosic biomass, into biofuels. New facilities may integrate multiple distributed pyrolysis units produc...
