The profitability and sustainability of future biorefineries are dependent on efficient feedstock use. Therefore, it is essential to valorize lignin when using wood. We have developed an integrated biorefinery that converts 78 weight % (wt %) birch into xylochemicals. Reductive catalytic fractionation the wood produces a carbohydrate pulp amenable bioethanol production oil. After extraction oil, crude, unseparated mixture phenolic monomers catalytically funneled 20 wt phenol 9 propylene (on...
A new generation lignocellulose biorefinery uses heterogeneous catalysis for the high-yield production of a handful chemicals from wood.
Upcoming bio-refineries will be at the heart of manufacture future transportation fuels, chemicals and materials. A narrow number platform molecules are envisioned to bridge nature's abundant polysaccharide feedstock production added-value intermediate building blocks. Such well-chosen lie base a large product assortment, while their formation should straightforward from refined biomass, practical energy efficient, without unnecessary loss carbon atoms. Lactic acid has been identified as one...
This work reports on the capability of O2-activated Cu−ZSM-5 and Cu-MOR zeolites to selectively convert methane into methanol at a temperature 398 K. A strong correlation between (i) activity (ii) intensity 22 700 cm-1 UV−vis band, assigned bis(μ-oxo)dicopper core, is found as function reaction temperature, Cu loading zeolite, (iii) in comparison other materials. These three lines evidence firmly support key role core this selective, low-temperature hydroxylation methane.
With these guidelines, we aim to unite the lignin-first biorefining research field around best practices for performing or reporting feedstock analysis, reactor design, catalyst performance, and product yields.
Effective ways to prevent lignin degradation during biomass fractionation are key for an easy lignin-to-aromatics conversion.
Driven by the depletion of crude oil, direct oxidation methane to methanol has been considerable interest. Promising low-temperature activity an oxygen-activated zeolite, Cu-ZSM-5, recently reported in this selective and active site reaction correlates with absorption feature at 22,700 cm(-1). In present study, band is used selectively resonance enhance Raman vibrations site. (18)O(2) labeling experiments allow definitive assignment observed exclude all previously characterized copper-oxygen...
Shift happens: Concerns about the depletion of fossil fuel reserves and environmental problems related to its use have encouraged development new catalytic approaches for producing carbon-based chemicals from cellulosic biomass. Here, recent progress in implementation (mainly) heterogeneous acid, bifunctional, multistep catalysis is reviewed.
Hydrotalcite-like anionic clays (HTs; or layered double hydroxides, LDHs) can be used as precursors to mixed oxides, but their catalytic potential reaches much further. This review demonstrates that HTs successfully applied in a broad spectrum of organic reactions, with advantages such improved activity, selectivity, metal dispersion, less waste production, and an recuperation immobilized catalysts. the as-synthesized form after different pretreatments. The HT is solid base or, depending on...
Electrochemical film growth of metal-organic frameworks (MOFs) enables the self-completing densely packed crystallite layers in a patterned fashion. Coatings produced this manner might prove useful integration MOF materials with devices such as sensors, concept that is illustrated by monitoring water adsorption.
Mesoporous silicas were functionalised with sulfonic acid groups; the resulting materials are excellent catalysts for formation of bisfurylalkanes and polyol esters.
A novel catalyst design for the conversion of mono- and disaccharides to lactic acid its alkyl esters was developed. The uses a mesoporous silica, here represented by MCM-41, which is filled with polyaromatic graphite-like carbon network. particular structure carbon-silica composite allows accommodation broad variety catalytically active functions, useful attain cascade reactions, in readily tunable pore texture. significance joint action Lewis weak Brønsted sites studied realize fast...
A strategic choice of catalyst during reductive lignocellulose processing is an effective tool to tune the hydroxyl content entire lignin product spectrum. This highly relevant for polymer applications.
Synthesizing more sustainable plastics Zeolites can help synthesize cheaper plastic precursors from biologically sourced feedstocks. Producing must compete with cost-effective petrochemical-based synthesis routes. Dusselier et al. developed a zeolite-based strategy to catalyze the transformation of microbially produced lactic acid into lactide, difficult-to-synthesize precursor biodegradable polylactic plastics. The selectivity nearly 80% is based on active site spatial confinement in...
