Abstract. Stable isotope measurements in atmospheric volatile organic compounds (VOCs) are an excellent tool to analyse chemical and dynamical processes in the atmosphere. While up to now isotope studies of VOCs in ambient air have mainly focussed on carbon isotopes, we herein present a new measurement system to investigate hydrogen isotope ratios in atmospheric VOCs. This system, consisting of a gas chromatography pyrolysis isotope ratio mass spectrometer (GC-P-IRMS) and a pre-concentration system, was thoroughly characterised using a VOC test mixture. A precision of better than 9 ‰ (in δ 2H)

Abstract:
Reactions of a disilenide, a disila analogue of vinyl lithiums, with two α,β-unsaturated carboxylic acid chlorides yield the first examples of compounds with a bicyclo[1.1.1]pentane scaffold that feature one carbon and one silicon atom at bridgehead positions; the formation of 1,2-disilabicyclo[1.1.1]pentan-4-ones is explained with initial nucleophilic substitution at the carbonyl C-atom by the nucleophilic disilenide and subsequent intramolecular [2+2]-cycloaddition of the Si=Si to the C=C double bond in a highly diastereoselective fashion.

Production of 2-pentanone, a methylketone, is increased in fasting ketotic humans. Its origin is unknown. We hypothesised that it is formed viaβ-oxidation of hexanoic acid by the peroxisomal pathway proposed for methylketone-producing fungi and yeasts. We usedPenicillium roqueforticultured on fat (margarine) to investigate 2-pentanone production. Headspace gas of incubates of the mould with a range of substrates was analysed using solid-phase microextraction with gas chromatography-mass spectrometry. Consistent with the proposed pathway, 2-pentanone was formed from hexanoic acid, hexanoyl-CoA,

In this study, a two-parameter computational thermodynamic analysis of a hydrogen-impurity mixture in a repurposed pipeline was performed. The hydrogen purity is a vital aspect of the hydrogen value chain, and it is essential to constantly monitor its purity.

Therefore, there is a need for such an analysis. This study considered two basic thermodynamic parameters: the pressure and gas molar concentration. The Peng–Robinson equation

The general correlation of two-phase pressure drop for an initial design purpose of evaporative micro-channel systems reported in [1] has been validated. For the water boiling in micro-channels, flow instability was observed. The instability criterion, proposed by Kandlikar [2], is able to predict the water experimental results. However, further examination of his criterion revealed that it can not predict the results of Brutin and Tadrist’s data of n-pentane.

Abstract:
Low emissions of NOx are obtained for a wide range of liquid fuels by using a staged prevaporizing-premixing injector. The injector relies on two stages of air temperature and fires into a laboratory jet-stirred reactor operated at atmospheric pressure and nominal ϕ of 0.6. The liquid fuels burned are methanol, normal alkanes from pentane to hexadecane, benzene, toluene, two grades of light naphtha and four grades of No. 2 diesel fuel. Additionally, natural gas, ethane and industrial propane are burned. For experiments conducted for 1790 K combustion temperature and 2.3±0.1 ms combustion resid

Abstract:
Abstract Sludge formation in oil wells results in near wellbore flow restriction or causes damage to electric submersiable pumps (ESP), thus, reducing their lifetime and causing operational upsets. Prevention and cleanout solutions of such deposits require understanding of sludge characterization and potential formation mechanism. The objective of this study is to present typical types of oilfield sludge and propose a systematic testing protocol to properly characterize organic/inorganic depositions. Examples of typical oilfield sludge deposits were obtained for the study that either organic,

Abstract:
Downhole fluid analysis (DFA) relies on accurate in-situ composition and gas-oil ratio (GOR) derived from vis-near infrared optical spectra. New advanced optical spectrometers have been introduced into the field on a new wireline formation testing platform. In this report, measurements of live crude oils collected with a research-grade spectrometer are compared with the same samples using DFA tools and logs. In addition, spectral interpretation using advanced machine-learning algorithms is shown to yield the same composition of C1 to C6+ as obtained from PVT reports within an absolute error ba
