Application of Stable Carbon Isotope Analysis to Continuous Coal/oil Coprocessing
نویسندگان
چکیده
'Solids formed from coprocessing of 10% coal/90% resid were characterized by solvent extraction, elemental analyses, C'3/C'z isotope ratio, ESR, and GPC techniques. adsorbed petroleum-derived material (oil, resin, asphaltene). The THF insolubles in the product contained high oxygen, low vanadium and a higher level of polyaromatic radicals than the soluble fraction, indicating that these insolubles were largely coal-derived material. However, the fraction of the solid product that could be dissolved in either THF or pyridine was kostly petroleum-derived. The total solids obtained from filtration contained at least 60%

The indication of origin of sesame seeds and sesame oil is one of the important factors influencing its price, as it is produced in many regions worldwide and certain provenances are especially sought after. We joined stable carbon and hydrogen isotope analysis with DNA based molecular marker analysis to study their combined potential for the discrimination of different origins of sesame seeds....
متن کاملBioleaching of Molybdenum from a Coal Liquefaction Catalyst Residue
bioleaching, molybdenum disulfide, catalyst residue Molybdenum disulfide, MoSz, is used as a catalyst in coal-oil coprocessing. For most processes using molybdenum catalysts to be economical, the molybdenum must be recovered and recycled. Chemical recovery schemes have been devised, but typically recover only a fraction of the molybdenum. There are reports in the literature that bacteria can ox...

Water and gas samples were collected from (1) nine shallow groundwater aquifers overlying Marcellus Shale in north-central West Virginia before active shale gas drilling, (2) wells producing gas from Upper Devonian sands and Middle Devonian Marcellus Shale in southwestern Pennsylvania, (3) coal-mine water discharges in southwestern Pennsylvania, and (4) streams in southwestern Pennsylvania and ...
متن کاملIsotopic fractionation of carbon and nitrogen during the illicit processing of cocaine and heroin in South America.
The forensic application of stable isotope analysis to cocaine and heroin for geolocation of exhibits must take into account the possible enrichment and/or depletion of 13C and 15N during the illicit manufacturing process. Continuous-flow elemental analysis-isotope ratio mass spectrometry was utilized to measure changes in the stable isotope ratios of carbon and nitrogen for both cocaine (N = 9...
