Problems solved by technology

[0004] Energy saving is not considered in the traditional metal fiber material manufacturing process, and the vacuum furnace equipment used requires additional hydrogen gas and power consumption, resulting in high equivalent carbon emissions in the fiber carrier manufacturing process
At present, there is no use of flow channel design in the stacked microchannel reactor to make the hydrogen generated in the reforming reaction process flow through the multi-scale fiber carrier, and provide the heat generated in the reforming reaction process to the fiber carrier to realize the sintering of the carrier. invention file

Embodiment 1

[0045] The sintering atmosphere is set to complete reduction atmosphere, low temperature reduction atmosphere, high temperature reduction atmosphere, neutral atmosphere and oxidation atmosphere, and the sintering time is set to 30min and 60min.

[0046] The so-called oxidizing atmosphere means that there is no gas protection during the sintering process; the neutral atmosphere means that the sintering is always under the protection of nitrogen; the high-temperature reducing atmosphere means that nitrogen is used to protect the fiber carrier first, and then hydrogen is introduced when the temperature rises to 600 °C. After the heat preservation is completed and the temperature is lowered to 600°C, the hydrogen valve is closed and then nitrogen gas is introduced; the low-temperature reduction atmosphere is similar to the high-temperature reduction atmosphere process, except that the gas conversion temperature is changed from 600°C to 400°C; Introduce hydrogen, and always keep sin...

Embodiment 2

[0057] like Figure 4 As shown, the methanol steam reforming microreactor is composed of an evaporation chamber and a reaction chamber, and the cut fiber sintered support (FSF) and smooth fiber sintered support (WSF) loaded with Cu / Zn / Al / Zr quaternary system catalyst into the reaction chamber. The reaction temperature was adjusted by a temperature controller. The syringe pump is injected with a certain proportion of methanol and water mixed liquid, and pumped into the evaporation chamber for vaporization, and then sent to the reaction chamber for reforming reaction. The hydrogen-rich gas obtained from the reaction is passed through a 0°C cold trap to separate unreacted methanol and water, and then the gas is sent to a gas chromatograph for gas composition analysis and a soap bubble flowmeter to measure the gas flow rate. The test principle is as follows Figure 7 shown.

[0058] Methanol conversion and hydrogen selectivity are important indicators for evaluating the perform...

Abstract

The invention belongs to the technical field of machine manufacturing and testing, and discloses a laminated microchannel reactor and mold pressing device integrated system and method. Nitrogen is injected into the laminated microchannel reactor at the speed of 100ml / min and calcinated for 2 hours at the temperature of 400 DEG C, then mixed gas of nitrogen at the speed of 100ml / min and hydrogen atthe speed of 50ml / min is injected and reduced for 1 hour at the temperature of 300 DEG C, and a catalyst is activated; and the reaction temperature is regulated by utilizing a temperature controller.The feeding speed of an alcohol-water solution is regulated by utilizing an injection pump; the alcohol-water solution is pumped into an evaporation board of the reactor to be gasified, and then sentto a catalytic reaction plate to react. The hydrogen-rich gas obtained through reaction passes through a zero DEG C cold trap so as to separate alcohol-water vapor which is not sufficiently reacted;the gas passing through the zero DEG C cold trap is sent to a gas chromatograph to analysis the gas components, and the gas flowing speed is measured by using a soap bubble flowmeter. The laminated microchannel reactor and mold pressing device integrated system has the wide prospects and market value.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and testing, and in particular relates to an integrated system and method of a laminated microchannel reactor and a molding device. Background technique [0002] In order to effectively increase the reaction rate in a limited volume in a hydrogen production microchannel reactor, the structure and processing of the catalytic reaction carrier is the key to the technology. At present, metal carriers with microchannel structures are mostly used in the world. In 1998, the Pacific Northwest National Laboratory of the United States first successfully applied microchannel metal carriers to hydrogen production reactors. Subsequently, researchers from various countries have developed microchannel metal carrier structures. Hydrogen reactor, and a preliminary theoretical discussion on the fluid velocity distribution of the key factors affecting the reaction rate. However, microchannels on th...
