摘要： Provided are a method for the catalytic conversion of hydrocarbons with a downer reactor and a device thereof. The specific process of the method is as follows: a raw material of hydrocarbons after being pre-heated (or not) and a low-temperature regenerant from a regenerant cooler entering an entry end of a downer reactor, flowing down along the reactor for reactions such as catalytic cracking, and a mixture of a reactive oil and gas and a catalyst descending to the end of the reactor for rapid separation, thereby achieving the rapid separation of the catalyst and the oil and gas. The main operation conditions thereof are as follows: the reaction temperature is 460 to 680° C., the reaction pressure is 0.11 to 0.4 MPa, the contact time is 0.05 to 2 seconds, and the weight ratio of the catalyst to the raw material (a catalyst-to-oil ratio) is 6 to 50. The separated catalyst to be regenerated (abbreviated as a spent agent) is stripped by means of a stripper, and enters a regenerator and is burned for regeneration, wherein the regeneration temperature is controlled at 630-730° C. The regenerant from the regenerator enters the regenerant cooler to be cooled to 200-720° C., and then enters the downer reactor for recycling

摘要： A method for circulating a cooled regenerated catalyst comprises the following steps: a regenerated catalyst derived from a regenerator is cooled to 200-720° C. by a catalyst cooler, which either directly enters into a riser reactor without mixing with hot regenerated catalyst, or enters the same after mixing with another portion of uncooled hot regenerated catalyst and thereby obtaining a hybrid regenerated catalyst with its temperature lower than that of the regenerator; a contact reaction between a hydrocarbon raw materials and the catalyst is performed in the riser reactor; the reaction product is introduced into a settling vessel to separate the catalyst and oil gas; the separated catalyst ready for regeneration is stream-stripped in a stream stripping phase and enters the regenerator for regeneration through charring; after cooling, the regenerated catalyst returns to the riser reactor for recycling.
