Abstract
An integrated method and an integrated device for heavy oil contact lightening and coke gasification are provided. The integrated method uses a coupled reactor including a cracking section and a gasification section, and the integrated method includes: feeding a heavy oil material into the cracking section to implement a cracking reaction, to obtain a light oil gas and a carbon-deposited contact agent; passing the carbon-deposited contact agent into the gasification section, so as to implement a gasification reaction, to obtain a regenerated contact agent and a syngas; and discharging the light oil gas and the ascended and incorporated syngas from the cracking section, to perform a gas-solid separation, so that the carbon-deposited contact agent carried is separated and returned to the cracking section, and a purified oil gas is obtained at the same time.
