Catalysis of the isomerisation and polymerisation of olefins on carbon blacks

Autor: P.H. Given, Loren W. Hill

Publikováno v: Carbon. 6:525-535

The catalysis of the polymerisation and/or isomerisation of C 4 , C 5 , and C 6 α-methyl mono-olefins on some commercial carbon blacks has been studied. Catalysis was observed only after the blacks had been heated at 100 to 115°C in vacuum for 20 t

Analysis of surface groups on carbon blacks

Autor: P.H. Given, Loren W. Hill

Publikováno v: Carbon. 7:649-658

Surface oxygen groups on carbon blacks were analyzed by several new techniques and some methods used previously were re-examined. Phenolic hydroxyl groups were converted to their acetate ester derivatives using radioactively labeled acetic anhydride

Some aspects of the mechanism and kinetics of coal liquefaction. [Role of oxygen functional groups in early stages]

Autor: P.H. Given, A.J. Szladow

Various processes are under development at the pilot plant stage for the conversion of coals to low-sulfur liquid fuels, using a hydrogen-donor solvent, a high partial pressure of hydrogen and, in some cases, a catalyst. It was the objective of this

Geochemical study of the inorganic constituents in some low-rank coals

Autor: R.N. Miller, P.H. Given

Because lignites contain acidic and other functional groups, the inorganic matter associated with them can consist not only of discrete mineral phases but also of cations associated with the organic matter. That much of the inorganic matter can be he

Investigation of the distribution of minerals in coals by normative analysis

Autor: N. Suhr, D. Weldon, P.H. Given

The distribution of minerals in 86 coals have been calculated from chemical analyses of high temperature ash (normative analysis) and the results compared with mineralogical analyses based on x-ray diffraction and IR spectrometry of low temperature a

Calculation of calorific values of coals from ultimate analyses: theoretical basis and geochemical implications. Final report. Part 8

Autor: P.H. Given, D. Weldon, J.H. Zoeller

The various formulae for calculating calorific values for coals from ultimate analyses depend essentially on a propositon due to Dulong, that the heat of combustion of an organic compound is nearly equal to the heats of combustion of the elements in

The mobile phase in coals: Its nature and modes of release: Part 2, Efforts to better define the nature and magnitude of the mobile phase: Final report

Autor: P.H. Given

Several liquefaction conditions and many extracting solvents were used in attempts to set up conditions such that, as the conditions became more severe, progressively more hexane-solubles, analyzable by GC/MS, would be released. It was hoped to ident
