Abstract
A carrier gas jet is injected into a liquid hydrocarbon material to form a liquid hydrocarbon-gas mixture; flowing the liquid hydrocarbon-gas material through an inter-electrode gap of a discharge chamber, the inter-electrode gap defined by a spaced pair of electrodes, the electrodes being connected to a capacitor; charging the capacitor to a breakdown voltage of the carrier gas; generating a spark discharge in the inter-electrode gap; and recovering a hydrocarbon fraction that includes lower molecular weight hydrocarbons than the liquid hydrocarbon material.
Claims21
A process comprising:
- introducing a liquid hydrocarbon material into a discharge chamber;
- flowing the liquid hydrocarbon-gas material through an inter-electrode gap within the discharge chamber, the inter-electrode gap defined by a spaced apart positive electrode (anode) and a negative electrode (cathode), both the electrodes being connected to a capacitor;
- injecting in the inter-electrode gap a carrier gas into the liquid hydrocarbon material to form a liquid hydrocarbon-gas mixture;
- charging the capacitor to a breakdown voltage of the carrier gas;
- generating a spark discharge in the inter-electrode gap;
- and
- recovering a hydrocarbon fraction comprising lower molecular weight hydrocarbons than the liquid hydrocarbon material.
An apparatus for cracking a liquid hydrocarbon material, the apparatus comprising:
- a discharge chamber;
- an inlet configured to convey a liquid hydrocarbon material to the discharge chamber;
- an outlet configured to convey a hydrocarbon fraction from the discharge chamber;
- an positive electrode comprising a first end and a second end;
- a negative, cannulated electrode comprising a first end and a second end;
- wherein the first end of the positive electrode is spaced apart from the first end of the negative electrode by a distance, the distance defining an inter-electrode discharge gap, and the cannulated electrode comprising a wall defining an open passage from the first end of the negative electrode to the second end of the negative electrode, the second end being distal from the first end;
- and the negative electrode is configured for passage of a carrier gas to the inter-electrode discharge gap;
- a storage capacitor connected to the electrodes;
- and
- a power supply configured to generate an spark discharge in the discharge gap.
