In addition to the traditional role that the FCC process plays in heavy oil cracking, nowadays this process is becoming increasingly important as a potentially flexible means to respond to changes in petrochemical product demand It is expected that the FCC process will play a ma…

The formation of coke from reacting asphaltenes is significantly affected by both reactions with the liquid components and the solvent properties of the liquid medium. Both the kinetics and phase behavior in the cracking of asphaltenes were studied in this thesis. The kinetics o…
Asphalt cement is viscoelastic material, which is time and temperature dependent. At high temperatures asphalt cement behaves as a viscous material. At below freezing temperatures it acts as a brittle solid and is more susceptible to temperature cracking. In order to improve bot…
This thesis describes the metallurgical and environmental factors that influence hydrogen embrittlement of super duplex stainless steels and presents a model to predict the rate at which embrittlement occurs. Super duplex stainless steel has an austenite and ferrite microstructu…
