Proceedings of the Workshop on Hydrocarbon Processing Mixing and Scale-Up Problems

Description: A workshop was convened by the Division of Fossil Fuel Utilization of the US Department of Energy in cooperation with the Particulate and Multiphase Process Program of the National Science Foundation to identify needs for fundamental engineering support for the design of chemical reactors for processing heavy hydrocarbon liquids. The problems associated with dispersing liquid hydrocarbons in a reacting gas and mixing within the gas phase are of primary concern. The transactions of the workshop … more

Report of Analyses for Light Hydrocarbons in Ground Water

Description: This report contains on microfiche the results of analyses for methane, ethane, propane, and butane in 11,659 groundwater samples collected in 47 western and three eastern 1° x 2° quadrangles of the National Topographic Map Series, along with a brief description of the analytical technique used and some simple, descriptive statistics.

The Mercury Photosensitized Reactions of Some Hydocarbons

Description: The problem was to study several hydrocarbons when they were subjected to ultraviolet light of 2536 Å in the presence of mercury vapor. It would be expected from the work of Stallings that the rupture of any tertiary hydrogen bond in the molecule would be the predominant effect. However, secondary and primary bond splitting would occur as well as some C-C bond rupturing, but these could be expected to a lesser degree than the first, since the t-hydrogen has the greatest reactivity.

Radical and Molecular Reaction Mechanisms for (γ, n) Activated c11 Reactions in Liquid Cyclohexane

Description: From abstract: "A study has been made of the yields of gaseous products labeled with C11 from the C12(γ, n) reaction in liquid cyclohexane. The effects of variations in the radiation dose and in the concentration of dissolved iodine during irradiation on the yields of these products were studied in order to elucidate the reaction mechanisms. A reaction model was developed as a method of assessing the relative importance of radical and molecular processes. The data suggest (1) that the formation… more

The Adsorption and Surface Reactions of Hydrocarbons on Clean Iridium

Description: From abstract: "The adsorption of ethane, ethylene and acetylene on clean iridium in a field emission microscope has been found to cause characteristic changes in the work function of the iridium surface. Further changes, which are time and temperature dependent, result when such surfaces are heated. Flash filament experiments have shown that the changes in work function upon heating are due to desorption reactions and that the desorbed product consists principally of hydrogen. By assuming a li… more

The Hydrolysis of the Rare-Earth Carbides

Description: From introductory paragraph: "This report concerns the hydrolysis of rare-earth dicarbides, sesquicarbides, solid solutions of carbon in rare-earth metals as well as rare-earth carbon alloys of varying compositions. Many of the carbide samples used in this study were those which had been studied by Gschneider (9)(7) and had been preserved in evacuated, sealed tubes. Some additional preparations of the sesquicarbides were made especially for these studies. The hydrolytic reactions were carried o… more

Polycyclic-Aromatic-Hydrocarbon-Induced Alterations in the Physio-Chemical Characteristics of Escherechia Coli Dexyribonucleic Acid

Description: Prior to 1965 the interactions of polycyclic aromatic hydrocarbons with DNA (Deoxyribonucleic acid) had been but moderately studied. It was concluded that, although a controversy existed, an apparent interaction occurred between DNA and certain aromatic hydrocarbon molecules and that the interaction was not an artifact of the reaction system.

Electrodeposition of Diamond-like Carbon Films

Description: Electrodeposition of diamond-like carbon (DLC) films was studied on different substrates using two different electrochemical methods. The first electrochemical method using a three-electrode system was studied to successfully deposit hydrogenated DLC films on Nickel, Copper and Brass substrates. The as-deposited films were characterized by scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), fourier transform infrared spectroscopy (FTIR) and cyclic vol… more
