  • Method for producing chemicals from crude oil by double-tube parallel multi-zone catalytic conversion
    Patent number: 11434437
    Abstract: A method for producing chemicals from crude oil by double-tube parallel multi-zone catalytic conversion is provided. The method may include the following steps: feeding the crude oil directly or separating the crude oil into light and heavy components by flash evaporation or distillation after desalination and dehydration; strengthening the contact and reaction between oil gas and catalyst by using two parallel reaction tubes with novel structure, controlling the reaction by zones, carrying out optimal combination on feeding modes according to different properties of reaction materials, controlling suitable reaction conditions for different materials, and increasing the production of light olefins and aromatics.

  • REACTOR AND METHOD FOR PROPYLENE PRODUCTION BY STRATIFIED INJECTION OF HEAVY OIL AND LIGHT OLEFINS
    Publication number: 20110275874
    Abstract: A riser reactor for propylene production, comprises pipelines with an upper part and a lower part, the upper part is a straight pipeline, and the lower part is a expanding-diameter pipeline, and the expanding-diameter pipeline is a circular truncated cone-shaped pipeline with an angle of 1˜60 o between generatrix and axes, wherein, the diameter of upper surface of the circular truncated cone-shaped pipeline is larger than or equal to the diameter of the straight pipeline. Employed the riser reactor, propylene is produced by the method of catalytic cracking with stratified injections of heavy oil and light olefins. Average gas linear velocity in axial direction of the straight pipeline of riser reactor is 3˜25 m/s, and that in the expanding-diameter pipeline is 0.1 to 5 m/s. The outlet temperature of the riser reactor is 460 to 600° C., and the light olefins are no more than 50% of the total feedstock by weight.
