ABSTRACT

Hydrogenation of residual oil, obtained from a petroleum distillation unit, provides a product with an increased hydrogen content. Catalyst deactivation is a major problem in the catalytic residual oil hydrogenation process. A study of hydrogenation of residual oil using a dispersed water soluble ammonium molybdate catalyst was conducted by A. R. Mohamed and V. K. Mathur. An alternative for hydrogenation of residual oil is to conduct the process without the use of a catalyst. A shuttering mechanism is designed and incorporated between the window and the reflective solid mirror to expose the resid oil sample for a few minutes at a time. Hydrogen and helium atmospheres are used for the resid oil hydropyrolysis and pyrolysis, respectively. The inlet and outlet to and from the reactor are then closed so that the resid oil rapid hydropyrolysis reaction can be carried out in a batch system.
