Description
Technical field
The present invention relates to a kind of methane of environmental technology field and the production method and the device of hydrogen, particularly relating to a kind of municipal wastes and sewage of adopting is production method and the production equipment that raw material can obtain methane and hydrogen simultaneously.
Background technology
The product of combustion of hydrogen is a water, without any pollution, so hydrogen fuel is that the Research on development direction is arranged most always.But natural hydrogen is to be present in a lot of compound such as water and hydro carbons with combined form basically, and obtain hydrogen will produce from these compounds.
Producing four kinds of the most frequently used methods of hydrogen now is (1) coal gas generation-water-gas shift methods, (2) hydro carbons (especially methane) steam reforming method, and (3) heavy oil partial oxidation process, (4) and water electrolysis method, its corresponding reactive chemistry formula is as follows:
Because H-O and H-C bond energy are big, without exception, the energy consumption of these processes own is all very big.Equipment requirements is than higher.The energy and the facility investment of these process raw materials itself fuel (even water electrolysis can think that also electricity is a fuel) and consume significant well imagine that product hydrogen price is surprising.Even very scale operation also roughly is " under the same calorific value, the price of hydrogen is at least more than the twice of gas price ".Hydrogen generated by electrolyzing water is because process energy efficiency low (only having an appointment 22%) consumption of electrode is big, and price is surprisingly high especially, except that special purpose (current about 5% hydrogen by water electrolysis process production) generally not in this way.Improve electrolyzer/electrode etc., operation conditions optimization can be raised the efficiency a little with other process coupling or the like, yet also very limited.
China utilizes anaerobic treatment to produce methane (biogas, methane) country the earliest, just begins to utilize fermentation using bacteria to handle ight soil in the southwest of China before 4000 and produces biogas.The principle of rubbish anaerobic treatment is not have to utilize the microbiological deterioration organic substance under the state of oxygen, generation methane and carbonic acid gas.At nearest 10 years, the anaerobic treatment technology obtained significant progress.On the basis that anaerobion is more and more understood, by to temperature, humidity, potential of hydrogen, reaction time, the isoparametric regulation and control of voltaile fatty acid, the productive rate of methane improves constantly.But by animal waste, municipal wastes etc. are produced the device of methane in practical application, and therefore its payback period is more common in American-European developed country generally at 5-10.
