Asphaltene Instability Measured by Small-Angle Neutron Scattering

Oct 19, 2011
Michael P. Hoepfner
Asphaltenes are defined as the petroleum fraction that precipitates with the addition of a normal alkane; however, it was only recently discovered that there is a strong time-dependency for precipitation in oil/n-alkane mixtures [1]. It was found that at low precipitant concentrations, asphaltenes...

Development of a Compact Fischer Tropsch Reactor

Oct 18, 2011
Lyman Frost
Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...
