PROCESS AND A SYSTEM FOR ENHANCING LIQUID YIELD OF HEAVY HYDROCARBON FEEDSTOCK

摘要

The present invention provides a process and a system for coking and simultaneous upgrading of a heavy hydrocarbon feedstock. More particularly the present invention relates to a process of cracking heavy hydrocarbon feedstock employing high heat carrier, incorporated with weak acid sites for improving the liquid yield and reducing coke yield. The feedstock is vaporized and brought in contact with a heat carrier material to produce a product stream and separating the product stream from the particulate heat carrier, regeneration of the particulate heat carrier to the extent of 10-30% and collecting a gaseous and liquid product from the product stream.

主权项

1. A process for coking and simultaneous upgrading of a heavy hydrocarbon feedstock, comprising:
a. providing a heated particulate material to a reactor chamber; b. dispensing preheated heavy hydrocarbon feedstock in the reactor chamber such that the same conies in contact with the particulate material at a temperature in the range of 480° C. to 620° C. c. allowing said heavy hydrocarbon feedstock to stay in contact with the particulate material for a predetermined time period to form a product mixture and a coke laden particulate material; and d. withdrawing the product mixture from the reactor chamber; characterized in that:
the preheated heavy hydrocarbon feedstock is dispensed as an atomized spray in the reactor chamber;the predetermined time period is such that the product comprises about 70 wt % to about 80 wt % of hydrocarbons having boiling point in the range of about 40 to 600° C.
