ABSTRACT:
A laboratory scale fluid catalytic cracking apparatus and method of use thereof, which provides cracking performance that emulates commercial riser cracking. The apparatus includes a reactor having a removable feed injector to quickly facilitate changing hydrocarbon contact time without varying the feed rate or diluent rates, or catalyst charge, and also without the expense of a new reactor. The feed injector is a tube within a tube design. The feed injector allows hydrocarbon feed as well as fluidization gas to be delivered to a prescribed axial position within a catalyst bed in the reactor to directly affect hydrocarbon contact time. The reactor also includes a conical bottom head having a conical section and a lower fluidization gas nozzle connected at its apex. The total included angle of the conical section may vary between 10.degree. and 1700.degree., however it is preferred to be in the range of The reactor geometry combined with the location of the fluid and gas sources generate the desired torroidal motion of the catalyst bed, which is significantly enhanced over conventional designs which do not use multiple nozzles and the conical bottom design.
