Abstract:
The invention provides a process of alkaline catalytic cracking of inferior heavy oil with double reaction tubes in milliseconds and gaseous coupling, the process comprising: a high-efficiency atomizing nozzle sprays the preheated heavy oil into an upper portion of a downflow reaction tube, the produced oil mist mixes with a high temperature regenerated alkaline catalyst flowing downward from a dual-regulation return feeder, so as to heat, vaporize and crack the oil mist, the obtained stream containing a cracked oil and gas and an alkali catalyst to be generated flows rapidly and downward to the bottom of the downflow reaction tube to carry out a gas-solid separation; then the cracked oil and gas obtained from the gas-solid separation enters a fractionation column to be separated, the oil slurry obtained by separating the cracked oil and gas returns to mix with the heavy oil for recyclable use, while the other products separated from the cracked oil and gas are output as intermediate products; the alkali catalyst to be generated obtained from the gas-solid separation is subject to steam stripping and enters into a lower portion of a riser gasification reactor and carries out a catalytic gasification reaction with an oxidant and water vapor at a reaction temperature of 750° C. to 1,000° C., the subsequently generated material stream containing synthesis gas and regenerated alkaline catalyst flows rapidly and upward to a top of the riser gasification reactor to carry out a gas-solid separation; the high-temperature regenerated alkaline catalyst obtained from the gas-solid separation flows into the dual-regulation return feeder, wherein a portion of the high-temperature regenerated alkaline catalyst flows into the downflow reaction tube to continue to crack the heavy oil, the remaining portion of the high-temperature regenerated alkaline catalyst returns to the riser gasification reactor so as to continue the regeneration gasification; the synthesis gas obtained from the gas-solid separation is subject to a heat exchange and then output as a product.

Claim (Index 2):
The process of alkaline catalytic cracking of inferior heavy oil with double reaction tubes in milliseconds and gaseous coupling according to  claim 1  wherein the oxidant is one of oxygen, air, and oxygen-enriched air.
