The invention discloses a multilayer stacked micro-channel reaction unit for methanation of CO2. The multilayer stacked micro-channel reaction unit is composed of an upper cover plate, a lower cover plate, and a micro-mixer 1, a micro-mixer 2, a micro-burner, a micro-heat exchanger 1, a micro-reactor 1, a micro-heat exchanger 2 and a micro-reactor 2 which are hermetically installed between the upper cover plate and the lower cover plate in sequence, wherein a vacuum diffusion welding manner is employed for seal connection of every two adjacent modules among the upper cover plate, the micro-mixer 1, the micro-mixer 2, the micro-burner, the micro-heat exchanger 1, the micro-reactor 1, the micro-heat exchanger 2, the micro-reactor 2 and the lower cover plate. The multilayer stacked micro-channel reaction unit can realize room-temperature starting and gradient utilization of reaction heat during methanation of CO2 in the field of renewable energy sources; reaction starting time is less than 30 min; the conversion rate of H2 is greater than 98% under the condition of a H2 / CO2 ratio of 4; so the energy utilization efficiency of a system is greatly improved, and distributed renewable energy sources are made full use of.
Description
technical field [0001] The invention belongs to the process intensification and system integration in the field of renewable energy, specifically related to CO 2 A multilayer stacked microchannel reaction system for methanation. Background technique [0002] The development of renewable energy, especially solar energy, wind energy, and biomass energy, is the research focus of countries all over the world. However, renewable energy generally has disadvantages such as low energy density, intermittency, and instability. How to convert it into "advanced energy" with high energy density and continuous output is an urgent problem to be solved in the process of the real practical application of renewable energy. The key issue. [0003] Using wind or solar energy to electrolyze water to produce H 2 , H 2 with CO 2 Methane is produced in the methanation unit, and methane can enter the natural gas pipeline network, refuel cars, or be stored and transported as LNG, etc., CO 2 It ...
