Claims
- 1. A process for enhancing the catalytic conversion of an oil feedstock containing liquid and vapor phases into hydrocarbon vapor products in a fluid catalytic cracking unit comprising the steps of:
- separating said oil feedstock into a vapor component and a liquid component; and
- atomizing said liquid component; and
- separately introducing said atomized liquid component and said vapor component into said cracking unit.
- 2. The process of claim 1 wherein said process further comprises the step of heating said oil feedstock prior to separating said feedstock into vapor and liquid components.
- 3. The process of claim 2 wherein said process further comprises the step of mixing said oil feedstock with steam prior to heating said oil feedstock.
- 4. The process of claim 1 wherein the step of atomizing the liquid component comprises contacting said liquid component with a high velocity carrier gas in a venturi nozzle.
- 5. The process of claim 4 wherein said process further comprises the step of pressurizing said liquid component prior to providing said liquid component to said venturi nozzle.
- 6. In a process for catalytic cracking therein an oil feedstock containing liquid and vapor phases is contacted with a cracking catalyst to form hydrocarbon vapor products in a fluid catalytic cracking unit, the improvement comprising:
- separating said oil feedstock into a vapor component and a liquid component;
- atomizing said separated liquid component by contacting said liquid component with a carrier gas;
- introducing said atomized liquid component and carrier gas into said cracking unit; and
- separately introducing said separated vapor component into said cracking unit.
- 7. The process of claim 6 which is further characterized to include the step of heating said oil feedstock prior to separating said feedstock into said vapor and liquid components.
- 8. The process of claim 7 wherein said separated liquid component is contacted with said carrier gas in a venturi nozzle.
- 9. The process of claim 8 which is further characterized to include the step of pressurizing said liquid component prior to providing said liquid component to said venturi nozzle.
- 10. The process of claim 9 which is further characterized to include the step of mixing said oil feedstock with steam prior to heating said oil feedstock.
