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.
