Nanosized Carbon Particles From Natural Gas Soot
Carbon nanoparticles were prepared by refluxing the combustion soot of natural gas in nitric acid. Transmission ElectronMicroscopymeasurements showed that the resulting particles exhibited an average diameter of 4.8( 0.6 nm, and the crystalline lattices were consistent with graphitic carbons. CNMRand FTIR spectroscopic measurements further confirmed the presence of sp carbons in the form of ary...
متن کاملSeparation of Carbon Dioxide from Natural Gas by Matrimid-Based Mixed Matrix Membranes
Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...
متن کاملOccupational exposure to carbon black in its manufacture.
Carbon black is manufactured by the vapour phase pyrolysis of heavy aromatic hydrocarbon feedstocks. Its manufacture is worldwide and the majority of its production is for use in the rubber industry especially tyre manufacture. Its carbonaceous nature has led many to investigate the occurrence of exposure-related medical conditions. To quantify any such relationships, it is necessary to assess ...
متن کاملCapturing carbon dioxide as a polymer from natural gas
Natural gas is considered the cleanest and recently the most abundant fossil fuel source, yet when it is extracted from wells, it often contains 10-20 mol% carbon dioxide (20-40 wt%), which is generally vented to the atmosphere. Efforts are underway to contain this carbon dioxide at the well-head using inexpensive and non-corrosive methods. Here we report nucleophilic porous carbons are synthes...
متن کاملSimulation of Bioreactors for PHB Production from Natural Gas
Recently, many economic studies of poly(3-hydroxybutyrate) PHB production on an industrial scale, and the impact of replacing petrochemical polymers by PHB were carried out, clearly indicating that the most crucial factors to reduce the cost of producing biopolymers are allotted to the application of microbial production strains capable of high productivi...
