Viscosity of characterized visbroken heavy oils

Visbroken products from a Western Canadian bitumen were generated at five different reaction conditions (temperature and residence time) in an in-house lab-scale continuous reactor unit. Visbroken products from a second Western Canadian bitumen and an Arabian vacuum bottoms were obtained from other sources. Densities and viscosities were measured for the whole oil, the maltenes, the distillates, the distillation residue, and the SARA (saturates,...
