An innovative BASF catalyst manufacturing technology (NanoSelect™) is introduced which allows production of heterogeneous catalysts with excellent control over metal crystallite sizes. NanoSelect™ enabled the development Pd are lead-free Lindlar replacements in alkyne-to-cis-alkene hydrogenations. Pt showed chemoselectivity substituted nitro-arene hydrogenation reactions without build-up hydroxylamine intermediates. All produced show markedly higher activity per gram leading to ten-fold less...
Positive discrimination: Supported MoVI promoted Pt nanoparticles (c-Pt+Mo/C) are successfully applied as catalysts in the chemoselective hydrogenation of functionalized nitroarenes. Mild conditions (30 °C, 4 bar H2, EtOH) prove sufficient for complete reduction to corresponding anilines, leaving other functional groups untouched. Turnover numbers at least 20 000 show that this catalyst is very tolerant halogen-containing aromatics.
Selective hydrogenation of nitroarenes to N-arylhydroxylamines at high rates over supported Pt-NPs.
Low-temperature Fischer–Tropsch (LTFT) synthesis converts syngas to diesel/wax at 200–250 °C. The LTFT reaction has recently received renewed interest, as it can be used for converting from renewable sources (biomass and waste) high-value fuels chemicals. Conventional reactors, such fixed-bed slurry are not entirely suitable bio-syngas conversion due their smaller scale compared fossil fuel-based processes. This review explores advancements in intensifying reactors conversion, enabling...
Usually the Rh-catalyzed hydroformylation of styrene predominantly yields branched, chiral aldehyde. An inversion regioselectivity can be achieved using strong π-acceptor ligands. Binaphthol-based diphosphite and bis(dipyrrolyl-phosphorodiamidite) ligands were applied in styrene. High selectivities up to 83% 3-phenylpropanal obtained with 1,1-bi-2-naphthol-based virtually no hydrogenation ethyl benzene. The coordination chemistry those towards Rh(I) was investigated spectroscopically structurally.
3D printing of catalyst has made a significant headway the past decade. Very often metal species on printed supports are being used in catalysis. However, there is no standardized method impregnation structures. In this work, impact step production process where done was studied. Cobalt alumina structures were synthesized using direct ink writing (DIW), characterized and tested Fischer-Tropsch synthesis. Three different methods (A) incipient wetness structure after (B) adding salt precursor...
Advanced biofuels are required to facilitate the energy transition away from fossil fuels and lower accompanied CO2 emissions. Particularly, jet fuel needs a renewable substitute, for which novel production routes technology needed that more efficient economically viable. The direct conversion of bio-syngas into is one such development could improve efficiency biomass processes. In this work, bifunctional catalysts based on hierarchical zeolites prepared, tested evaluated their potential use...
Conventional fixed-bed reactors with conductive internals have shown excellent heat management in the Fischer–Tropsch synthesis, enabling much higher liquid productivity by avoiding thermal runaway.
Climate changes will have a huge impact on society, one that cannot be truly predicted. However, what is known our dependence fossil feedstock for energy, fuel and chemical production need to shift towards more biobased circular feedstock. This paper describes part of an important technology development uses biogenic plastic-containing waste streams the co-production aromatics with fuels and/or chemicals. captures first decade this from idea large Process Demonstration Unit operated...
