Abstract
This invention provides a two-stage visbreaking process for increasing the production of a visbroken hydrocarbon product from heavy oil feedstock, which meets heating oil viscosity specifications with little or no blending with external cutter stocks. The second stage visbreaking is conducted at a relatively high Severity in contact with a fluidized bed of particulate solids.
