All scientific approaches to the origin of life share a common problem: a chemical path to lipids as main constituents of extant cellular enclosures. Here we show by isotope-controlled experiments that unsaturated C3,5,7,9-monocarboxylic acids form by one-pot reaction of acetylene (C2H2) and carbon monoxide (CO) in contact with nickel sulfide (NiS) in hot aqueous medium. The primary products ar...

In the present study, tin-promoted Pd/MWNTs nanocatalystwas synthesized via polyol technique for application in hydrogenation of high-concentrated acetylene feedstocks. TEM images showed a restricted distribution of nanoparticles in the range of 3-5 nm. The results indicated that nanoparticles sizes were resistant to further catalyst deactivation. XRD patterns signified alloying between Pd and ...

Industrial purification of propylene and ethylene requires cryogenic distillation selective hydrogenation over palladium catalysts to remove propane, ethane and/or trace amounts acetylene. Here, we report the excellent separation equimolar mixtures propylene/propane ethylene/ethane, a 1/100 mixture acetylene/ethylene by highly robust microporous material, MFM-520, under dynamic conditions. In s...

The Cover Feature shows highly selective and coke-resistant atomically dispersed Pd catalysts via ionic liquid (IL) layer deposition for acetylene hydrogenation to ethylene in excess ethylene. In their Research Article, I. Ro co-workers explain that IL on induces a change the electronic structure of species, eventually improving coke resistance stability This study presents novel synthetic appr...

The front-end process integration of the selective acetylene hydrogenation provides several advantages over tail-end option. But extensive knowledge and reaction kinetics are required. This work combines ideal conditions advanced TEMKIN reactor in a laboratory plant for gradient-free kinetic analysis eggshell catalyst under industrially relevant conditions. With this system an industrial state ...
