    摘要: The present invention provides a fluidized catalytic process for production of dimethyl ether from methanol, wherein said process is carried out in a reactor in which the catalyst is in a fluidized state. Said process comprises the following steps of (1) feeding the methanol feedstock via two or more locations selected from the bottom, lower part, middle part and upper part of the reactor, contacting with the catalyst for preparation of dimethyl ether by methanol dehydration, carrying out the reaction of preparing dimethyl ether by methanol dehydration to obtain the reaction stream, separating said reaction stream to obtain a coked catalyst and a crude product primarily containing the target product, i.e. dimethyl ether; (2) totally or partially feeding the coked catalyst obtained in step (1) into a regenerator in a continuous or batch manner for regeneration via coke-burning, the regenerated catalyst being directly recycled to step (1) after being totally or partially cooled.

    摘要: This discloses a process for catalytically cracking hydrocarbon stocks in a riser or fluidized bed reactor simultaneously to increase yields of diesel and liquefied gas. The process includes the steps of: first, charging a gasoline stock and a catalytic cracking catalyst into a lower zone of the reactor to permit contact between the catalyst and the gasoline stock and to produce a liquefied gas-rich oil-gas mixture containing reacted catalyst. The resulting liquefied gas-rich oil-gas mixture (still containing reacted catalyst) is then introduced into a reaction zone above the lower zone of the reactor. Simultaneously, at least one conventional catalytic cracking hydrocarbon feed is also fed independently into at least two sites is situated at a different height above the lower zone of the reactor. The resulting mixture is then separated in a conventional fashion.
