Abstract

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 hydrodeoxygenation cannot be carried out, the invention provides the device and the method capable of efficiently converting the phenolic substances in the bio-oil and implementingcontinuous hydrodeoxygenation by using a hydrogen donor instead of a hydrogen source.

Description

technical field [0001] The invention belongs to the field of biomass energy, and in particular relates to a method for preparing fuel by continuous hydrogenation and deoxygenation of bio-oil. Background technique [0002] The energy crisis and environmental degradation are constantly threatening the sustainable development of human society. Therefore, it is urgent to find a new energy source that is rich in sources, renewable, and conducive to environmental improvement and sustainable development. Biomass energy is a kind of abundant, cheap, easy-to-obtain and environmentally friendly renewable energy that green plants directly or indirectly convert solar energy into chemical energy and store in biomass through photosynthesis. Biomass can be converted into gas, liquid and solid fuels. Its total consumption is second only to coal, oil and natural gas, and it is the fourth largest energy consumption in the world. Therefore, the development and utilization of biomass energy has...
