    摘要： The present invention relates to a catalytic conversion apparatus, characterized in that said apparatus comprises at least one feed oil cracking riser reactor, a dense bed reactor, a disengager, and a stripper, wherein said stripper locates below said dense bed reactor and communicates directly with the lower part of the dense bed reactor or through a fluid-communicating channel, the outlet of at least one of said riser reactor(s) communicates with the lower part of said dense bed reactor or any part of said fluid-communicating channel, the outlet of said dense bed reactor communicates with the inlet of a gas-solid separating apparatus located in said disengager through said disengager and/or through an optional transporting channel, the catalyst outlet of said disengager communicates with at least one position selected from the upper part of said stripper, any part of said fluid-communicating channel, and the lower part of said dense bed reactor, through at least one catalyst transporting channel. The catalytic conversion apparatus according to the present invention sets up at least one riser reactor and a dense bed reactor to carry out further cracking of the intermediate products, produced from the feed oil by the cracking reaction in the riser, in the dense bed reactor. Moreover, the spent catalysts discharged from the outlet of the dense bed reactor can be introduced into the stripper via a specific catalyst transporting channel, so as to maintain higher activity and temperature of the catalyst in the dense bed reactor and be advantageous to deeper cracking of the intermediate products in the dense bed reactor so as to produce more light olefins, particularly propylene.

    摘要： A process for producing ethylene from ethanol combining the catalytic conversion of hydrocarbons: an ethanol feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, and a coked catalyst and an target product of ethylene are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, a spent catalyst and an oil vapor are obtained after separating the reaction stream, and the oil vapor is further separated to give the products such as gas, gasoline and the like; a part or all of the coked catalyst and a part or all of the spent catalyst enter the regenerator for the coke-burning regeneration, and the regenerated catalyst is divided into two portions, wherein one portion returns to be contacted with the hydrocarbon feedstock, and the other portion, after cooling, returns to be contacted with ethanol feedstock. This process not only reasonably utilizes the excessive thermal energy of the hydrocarbon conversion, but also solves the problem of heat supply for the conversion of ethanol, thus ensuring the continuous catalytic conversion of ethanol and generating enormous economic benefits. For the catalytic conversion of the ethanol, the content of ethylene is 95 vol% or more in the gas product; and the conversion of ethylene is not less than 99%. For the catalytic conversion of the hydrocarbons, the yield for the light olefins increases slightly by at least 2 mol%.
