The invention discloses a continuous flow serpentine micro-channel condensation photo-thermal coupling catalytic hydrogen production reaction device, which mainly comprises a micro serpentine flow channel reaction module, a flow meter, a heater, a gas purging device, a circulating pump, a heat exchanger and the like. A purpose of the invention is to provide an effective and sustainable micro-reaction device for a novel photo-thermal coupling catalytic hydrogen production catalyst. According to the invention, the implementation process of the device mainly comprises: removing the oxygen in thereaction liquid by using the inert gas before the reaction through the temperature of the thermocouple reaction liquid, opening the circulating pump, feeding the fluid into the serpentine flow channelreaction device, achieving the photo-thermal catalytic hydrogen production process in the micro-flow channel under the condensation irradiation of a xenon lamp and other simulation light sources, making the generated gas enter the part above the liquid in the liquid storage bottle under the driving of the fluid pressure, collecting the gas, and analyzing the gas, wherein the flow in the pipelineand the temperature of the fluid are precisely controlled by the flow meter and the heat exchanger; and with the device, the continuous hydrogen production under the photo-thermal coupling condition is achieved by connecting the devices in series, the operation is convenient, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of new energy preparation, and in particular relates to a continuous-flow serpentine microchannel concentrating light-heat coupling catalytic hydrogen production reaction device. Background technique [0002] In recent years, in the field of energy, the massive utilization of traditional fossil energy such as coal and oil has caused serious pollution to the environment. Using new renewable energy to replace traditional energy is an effective technical means to solve environmental problems. Among these renewable energy sources, hydrogen energy is considered to be "the cleanest energy source in the 21st century". Internationally, developed countries including Europe, the United States, and Japan are also fiercely competing in the commercialization of hydrogen fuel cell vehicles. Converting into hydrogen energy and realizing large-scale and efficient hydrogen production process is the bottleneck of many scientific resear...
