Embodiment

[0063] Table 1 shows some experimental results of the hydrogen production reaction of glucose liquid supercritical water gasification carried out in the reaction device system of the present invention. Firstly, experiments and tests were carried out on glucose in a large experimental range. The results showed that 923K, 25MPa, 0.4mol / l glucose, the gasification rate can exceed 100%, and the liquid product is colorless, transparent and recyclable.

[0064] Table 2 shows the gasification experimental results of the CMC aqueous solution, and the CMC aqueous solution is easy to gasify. Better gasification results can be obtained at a higher concentration (8wt%), and the carbon gasification rate can reach more than 90%, which can be used as an additive for biomass gasification.

[0065] Table 3 shows the gasification results of glucose / alkaline additives and sawdust / CMC aqueous solution. Add KOH and Na to the raw material 2 CO 3 Studies have shown that K + 、Na + , the addition...

Description

[0001] 1. Field [0002] The invention belongs to the technical field of pollution-free renewable energy conversion, and in particular relates to a continuous supercritical water gasification hydrogen production method and device of organic solid matter. 2. Background technology [0003] Supercritical water can dissolve most organic substances and gases, and has unique physical and chemical properties such as high density, low viscosity, and strong transport capacity, making it a good medium for organic and gaseous reactions. In the supercritical water environment, many physical and chemical reactions are rapid, the unit processing capacity is large, and the size of the reaction equipment is small. At present, it is mainly used in supercritical water treatment of liquid waste, such as Chinese patents 98120547.x, 98241717.9 and 00268712.7. Typical supercritical water oxidation process and equipment for wastewater treatment. 97102903.2 Use supercritical water to decompose molte...
