も問題となっている。However, in these days when global warming due to carbon dioxide gas is a problem, even if the quality and yield can be improved by applying carbon dioxide gas, it is necessary to use far more carbon dioxide gas than is actually necessary for the application of kerosene. The generation of carbon dioxide by burning fossil fuels such as carbon dioxide and LPG, and the diversion of industrial carbon dioxide gas made from fossil fuels are also problems in related fields.

As a result, carbon dioxide gas, which is highly concentrated in methane fermentation gas generated by methane fermentation of biomass such as sewage treatment sludge, can be used cheaply and efficiently, and its global warming effect is 20 to 40 times that of carbon dioxide gas. They discovered that these problems could be solved by burning methane, which is said to be a strong carbon dioxide gas, and converting it into carbon dioxide, while at the same time recovering and effectively using the heat.

。In other words, large amounts of carbon dioxide gas are released along with methane gas from such biomass, and conventionally, these gases were released into the atmosphere as they are, but the present inventors first developed a pressure swing method to extract these gases. After learning that carbon dioxide gas can be efficiently recovered and highly purified methane can be obtained, a patent application was filed (Japanese Unexamined Patent Publication No. 122018/1983). After further investigation, it was discovered that this technology could be applied to improve carbon dioxide application.

Hereinafter, the apparatus is more preferably operated according to a conventional method at a pressure of about 2 to 5 kg/cm'G. If the pressure is too high, equipment costs will be high, and energy costs will also be high. Also, if the pressure is too low, the device will become too large, which is not a good idea. As the adsorbent, known ones such as carbon molecular sieve, zeolite molecular sieve, silica gel, alumina gel, etc. can be used alone or in combination, and carbon molecular sieve is particularly preferred in terms of processing capacity, service life, etc. .

吸着剤によっては、より低温にし、脱水、乾燥をする。Gas generated in methane fermentation facilities usually has a temperature of about 35 to 55 degrees Celsius and is saturated with water, so it is heated to 40 degrees Celsius.
Hereinafter, it is preferable to cool the material to about 20.degree. C. to reduce the moisture content and then subject it to a pressure swing. Also,
Depending on the adsorbent, the temperature may be lower, followed by dehydration and drying.

Note that the term "methane" used in this specification means a high-calorie gas rich in methane obtained by separating carbon dioxide gas from methane fermentation gas.

。The accumulated carbon dioxide is removed from the tank by appropriate means depending on the desired carbon dioxide concentration in the greenhouse, such as manually or automatically in combination with an appropriate carbon dioxide supply pipe or on-off valve, or intermittently or continuously. It is supplied into the greenhouse for a predetermined period of time. The carbon dioxide concentration in the greenhouse can be measured using a known sensor, gas detector, or the like. It depends on the target plants, etc., but normally in a greenhouse there is about 350 ppm of carbon dioxide in the natural state, but in order to promote photosynthesis, 700 ppm of carbon dioxide gas is present.
It is said that the presence of carbon dioxide gas of ~3,000 ppm is preferred. In order to maintain this carbon dioxide concentration during photosynthesis, for example, in a greenhouse with an area of 10 are and a height of 3.5 m,
When applying carbon dioxide gas for 4 hours from 8 a.m. to 12 noon on Sundays, 1 to 10 kg of carbon dioxide gas is required per hour.

とができる。On the other hand, the accumulated methane has a caloric value of, for example, 2,000-3,000 compared to the gas generated by fermentation.
It has an increase of 0 Kcal/Nm' and can be supplied to a suitable combustion device such as a burner and burned with other auxiliary fuels for heating a greenhouse if necessary. Normally, 0.5 to 0.7 kg of methane is obtained per 1 kg of carbon dioxide gas, so the obtained methane is not only used for combustion, but also used as fuel for heat engines such as gas engines and gas turbines, and used for power generation. It can be converted into various types of energy such as power, hot air, steam, hot water, and cold water, and can be used to power pressure swing devices, control weather conditions in greenhouses, etc.
It can be used for managing methane fermentation facilities and for other heating and cooling purposes.

１１により、制御される。The pressurized gas is introduced into an adsorption tower 4 filled with an adsorbent. The adsorption tower includes at least one tower, preferably two or more towers as shown in FIG. 1, and the pressure of the six towers is alternately varied to alternately adsorb carbon dioxide gas in the fermentation gas. The higher the number of columns, the higher the recovery rate of carbon dioxide gas, but the equipment cost also increases, so 2 to 6 columns is generally preferred. The methane from which carbon dioxide gas has been adsorbed and separated passes through the adsorption tower, is introduced into the tank 5, and is stored therein. On the other hand, the adsorbed carbon dioxide gas is desorbed by the vacuum pump 6, introduced into the tank 7, and accumulated. The carbon dioxide gas accumulated in the tank 7 is supplied into the greenhouse 8 via the supply means 9 according to the carbon dioxide concentration within the greenhouse 8 . Further, the methane accumulated in the tank 5 is sent to a burner or a heat engine 10, where it is consumed as fuel, and is used to control weather conditions such as heating and cooling in the greenhouse 8, or as an energy source for a methane fermentation facility or other purposes. The supply of carbon dioxide gas and methane is controlled by control means 11 according to desired conditions.
