upon Tyne, New castle upon Tyne, NE1 7RU, England). The kinetics of gasification by molecular oxygen of a heat treatment series (1200-3200Β°K) of a graphitizing carbon prepared from polyvinyl acetate have been studied in the temperature range 750-1000Β°K. A correspondence between the activation energy for the reaction and the residual hydrogen content of the carbon was observed, the hydrogen ,apparently acting in a catalytic role. 36. The effect of heat-treatment on the reaction of a porous carbon with carbon dioxide B.

Pure graphitizable carbons have been prepared from polyvinyl acetate at heat treatment temperatures (HTT) of 1200-3200K. Carbons doped with V, Cr, Mn, Fe and Co, by additions of organometallic compounds to the vinyl acetate monomer, of HTT 12OOK, were also prepared. Carbons from acenaphthylene, H'lT
The structure factor S(Q) of supercritical carbon dioxide has been measured over a wide range of the scattering vector Q (0.018-30 ,~-1) using two neutron apparatuses. The measured S(Q) has been Fourier transformed into the neutron weighted radial distribution function, GN(r). This measurement enabl
## Abstract The oxidation and carburization of two 20 Cr 30 Ni alloys with nominally 0 and 0.5 wt % Si have been investigated by cyclic exposure to carbon monoxide and carbon dioxide at 1000Β°C. In carbon monoxide a chromium oxide film is formed which inhibits further carbon deposition. In carbon d
Transient isotopic experiments (i.e., step response and temperature-programmed desorption (TPD)) have been applied on calcium-carbon samples to obtain a consistent explanation of the carbon gasification reaction catalyzed by calcium. The use of "CO2 shows the complexity of the TPD experiments result
