Device and method for preparing fuel by continuous bio-oil hydrodeoxygenation

The invention belongs to a device for preparing a fuel by continuous bio-oil hydrodeoxygenation. The device comprises a raw material tank, a gasification chamber, a reaction device and a collection device, wherein the raw material tank communicates with the gasification chamber, the reaction device comprises a reactor A and a reactor B, the reactor A and the reactor B are respectively provided with an air inlet and an air outlet, the gasification chamber communicates with the air inlets of the reactor A and the reactor B by pipes, the collection device communicates with the air outlets of thereactor A and the reactor B by pipes respectively, a gas supply device is further arranged on the gasification chamber, and the gas supply device can replace air in inner cavities of the gasificationchamber, the reaction device and the collection device. Compared with the prior art, aiming at the problems that phenolic substances in bio-oil are difficult to convert, the consumption of H2 is largeand the continuous hydrode
