Description

[0001] The present invention relates to an apparatus for producing hydrogen using microorganisms and a method for producing hydrogen using the same.

The present invention relates to a device for producing hydrogen using microorganisms and a method for producing hydrogen using the same. More specifically, the present invention relates to a method for producing hydrogen using a microorganism, which comprises supplying a medium containing steam for microbial growth, An apparatus for producing hydrogen by a microorganism including a gas inlet and an outlet for supplying a feed gas for hydrogen production and a gas inlet and outlet for discharging a product gas containing hydrogen and a microorganism reacting by the microorganism; And a method for producing hydrogen using the same.

Gas containing carbon monoxide, which is produced in large quantities, includes syngas produced through coal gasification or natural gas reforming, and by-product gas produced as a by-product in steelworks or petrochemical processes.

Coal gasification technology is a technology to produce syngas composed mainly of carbon monoxide and hydrogen through gasification reaction at high temperature and high pressure without directly burning coal. Through this gasification technology, coal can be used efficiently and environmentally clean have.

COG (Coke Oven Gas), BFG (Blast Furnace Gas), LDG (Linze Dnawitz Gas) and converter gas are the by-products of the steelworks. LDG is the most carbon monoxide in the by-product gas of the steelworks.

In order to produce hydrogen by using a gas containing a large amount of carbon monoxide such as syngas or byproduct gas (hereinafter, referred to as 'raw material gas' or BG), a water gas conversion process is performed. Conventionally, a thermochemical water gas conversion process is mainly utilized . FIG. 1 is a simplified schematic diagram of an entire process 100 for producing hydrogen from synthesis gas through common coal gasification.

As shown in FIG. 1, the air separation apparatus 110 first separates the introduced air into oxygen and nitrogen, and then supplies oxygen as an oxidizing agent to the gasification apparatus 120. The gasifier 120 supplied with oxygen from the air separation unit 110 generates synthesis gas (CO, H 2 , CO 2 , CH 4 , H 2 S, etc.) by incomplete combustion and gasification of coal. The syngas and scrubber 130 cleans impurities of the syngas produced in the gasification unit 120, and provides cooling to the water gas shift unit 140. The water gas shift device 140 provided with the syngas cooled from the syngas cooler 130 converts the carbon monoxide into carbon dioxide and hydrogen through a water gas conversion reaction (CO + H 2 O? CO 2 + H 2 ) And supplies the generated gas to the syngas purification apparatus 150. The syngas purifier 150 purifies carbon dioxide, hydrogen, a product gas mainly composed of methane (CH4), and supplies it to the carbon dioxide separator 160. [ The carbon dioxide separator 160, which receives the generated gas from the syngas purifier 150, separates carbon dioxide from the generated gas and supplies the separated carbon dioxide to a carbon dioxide processor (not shown). Pressure swing adsorption (PSA) 170, which is supplied with purified gas from the carbon dioxide separator 160, is a method of desorbing gas from the adsorbent by increasing the pressure to adsorb the gas to the adsorbent and lowering the pressure Separate the hydrogen. The hydrogen separated from the pressure swing adsorption device 170 can be used for power generation using the gas turbine or the fuel cell or as the raw material itself. Residual gas, other than hydrogen, used as a feedstock is provided to the gas turbine (180). The high-temperature combustion gas discharged from the combustor of the gas turbine 180 is supplied to the waste heat recovering device 181. The waste heat recovering device 181 recovers the waste heat discharged from the combustion gas discharged from the gas turbine 180 and provides it to the steam turbine 182 for generating steam.

A conventional thermochemical water gas conversion process 10 for producing hydrogen using syngas or by-product gas is shown in detail in FIG. 2, although some detailed configurations may differ depending on the type of source gas BG to be supplied . This corresponds to the detailed configuration of the water gas shift device 140 of FIG.

As shown in FIG. 2, the thermochemical water gas conversion process includes a high temperature water gas conversion reactor 13 operating at a high temperature of 350 to 450 ° C. and a low temperature water gas conversion reactor 15 (low temperature water gas conversion reactor) ). A first cooler 14 such as a cooler or a heat exchanger for cooling the gas temperature to 250 ° C should be installed between the high temperature water gas shift reactor 13 and the low temperature water gas shift reactor 15, A second cooler 16 for cooling the gas temperature reacted at 300 ° C to 350 ° C should also be provided.

The hydrogen production reaction proceeds rapidly through the hot water gas shift reactor 13, but the conversion rate is thermodynamically low. Therefore, it is necessary to convert the remaining carbon monoxide into hydrogen through the low temperature water gas shift reactor (15). The reaction rate of the low temperature water gas conversion reaction is relatively low in comparison with the high temperature water gas conversion reaction, but has a merit that a high conversion rate can be obtained. Thus, in order to obtain hydrogen through the existing thermochemical water gas conversion reaction, two or more reactors (13, 15) operating at high temperature and low temperature are required.

In addition, in order to perform a high-temperature water gas conversion reaction, it is necessary to preheat the temperature of the introduced gas to 250 ° C which is the active temperature of the catalyst (Cu, Fe, Co-Mo, etc.) The device 12 must be installed.

Thus, in the conventional water gas conversion step, the gas preheating device 11 that flows into the high temperature / low temperature water gas conversion reactor and the high temperature water gas conversion reactor 13, the steam supply device 12 necessary for the water gas conversion reaction, A heat exchanger 14 for cooling the gas discharged from the conversion reactor, and the like. In order to adjust the temperature of each reactor, there is a difficulty in the process such as gas preheating or heat exchanger condition must be predetermined.

Recently, the biogas water gas conversion process, which is focused on, is a process for producing hydrogen using a microbial water gas conversion reaction. The biological water gas conversion reaction using microorganisms is different in that the thermochemical water gas conversion reaction and the reaction formula are the same as each other but the microorganism is used instead of the catalyst for the thermochemical water gas conversion reaction.

CO (g) + H 2 O (1)? H 2 (g) + CO 2 (g)? H = 2.8 KJ / mol

The technical contents related to the biological water gas conversion process are described in Patent Documents 1, 2, and 3. Conventional patent documents disclose only the basic contents of the basic process and batch type related to the biological water gas conversion process, and the configuration for improving the overall reaction efficiency by constituting a continuous process using the raw material gas has been studied none

In the case of the biological water gas conversion process, the temperature control of the reactor is very important, but the reactor has not been studied. Particularly in the case of the microorganism used in the present invention, there is a problem that the reactivity drops sharply when the temperature of the culture solution containing seawater is below 75 캜. On the other hand, if the temperature exceeds 90 ° C., there is a problem that microorganisms die. In order to achieve optimum reactivity while surviving microorganisms, the temperature is lower than 90 ° C, but it is necessary to operate close to this temperature. In order to prevent the irreversible microorganisms from dying, very precise control is required even though it is a large capacity reactor. Was not presented.
