Description

Synthetic gas system of bio-crude produced through a fluidized bed reactor for rapid pyrolysis of biomass {GASIFICATION SYSTEM OF BIO-CRUDE PRODUCED THROUGH FLUIDIZED BED REACTOR FOR BIOMASS RAPID PYROLYSIS}

The present invention relates to a bio-crude gasification system, and more particularly, a fluidized bed reactor for rapid pyrolysis of biomass capable of producing various high value-added synthetic fuels by producing syngas with high calorific value using steam or oxygen as a gasifying agent. It relates to a synthesis gasification system of bio-crude produced through.

Recently, energy demand is increasing, and the increase in the use of fossil fuels has caused global warming and various climate and environmental pollution problems. Therefore, research on new and renewable energy is being conducted internationally to reduce dependence on fossil fuels and to solve climate and environmental pollution problems. Such new and renewable energy includes various energy sources such as hydropower, wind power, solar heat, hydrogen, bio, and waste. Among them, bioenergy, which is a carbon-neutral energy, is an eco-friendly energy source as it does not change the concentration of carbon dioxide in the atmosphere through carbon fixation. Is in the limelight.

In addition, in line with national goals and systems such as reducing CO ₂ emissions, increasing the proportion of bioenergy and the mandatory mixing system for renewable fuels (RFS), much interest and research are being conducted in Korea.

In general, bioenergy is an energy source that produces heat, electricity, and biofuel through thermochemical and biological processes using agricultural, forestry biomass, and organic waste as raw materials. The process of thermochemically decomposing biomass is largely divided into carbonization, pyrolysis, and gasification, and appropriate processes are applied according to the type of target product.

Among the thermochemical decomposition processes, the rapid pyrolysis process is performed under a reaction temperature of about 500 ℃, a short gas residence time of 2 seconds or less, and an oxygen-free condition, and the bio-crude among biomass thermochemical decomposition products such as bio-crude, bio-char, and non-condensed gas. It is a process that can maximize the yield. Bio-crude is a liquid fuel and has an advantage of being easy to store and transport with a high energy density compared to gaseous and solid fuels.

On the other hand, this rapid pyrolysis process remains at the pilot level, which has not reached the level of commercialization until now.

In addition, research on the reforming process is more important than the production of bio-crude. Among various types of reactors, a fluidized bed reactor is mainly used in the process of producing biocrude.

The fluidized bed reactor has a high heat transfer effect by vigorous mixing of a reactant and a fluid medium due to the influence of bubbles generated at the bottom, and has the advantage of achieving a stable reaction by maintaining a uniform temperature inside the reactor due to the fluidized medium.

On the other hand, synthetic gas produced using air as an oxidizing agent can be used in the form of co-fired or burned-off in existing combustion devices such as engines, boilers, and gas turbines, thereby producing electricity and thermal energy.

When steam or oxygen is used as a gasifying agent, it is possible to produce syn-gas with a higher calorific value than air, and synthetic natural gas, FT diesel, methanol, ethanol, hydrogen or DME through an appropriate purification process and composition control process. It can be used to produce high value-added synthetic fuels such as.

In addition, fuel production technology through biological conversion is also being developed. The TCI (total capital investment; based on 2000 t/day biomass treatment) for biomass direct gasification is 560 $million, and the TCI for rapid pyrolysis and bio-crude gasification (based on biomass 2000 t/day treatment) is 510 $million. Crude oil gasification is economically advantageous.

The reason why biomass gasification is not readily commercialized is because the burden of cleaning or dust collection facilities for purification of syngas increases when the existing combustion system is operated for a long time due to the generation of tar or soot from biomass materials.

Bio-crude gasification technology enables high-quality synthesis gas production because the tar concentration in the synthesis gas is lower and the yield of hydrogen and carbon monoxide is higher than that of biomass gasification technology.

It is a figure which shows the structure diagram of a process.

First, a rapid pyrolysis system for bio-crude production will be described with reference to the configuration schematically showing the rapid pyrolysis system for bio-crude production of FIG. 1.

The rapid pyrolysis system for bio-crude production of the present invention is an apparatus for condensing tar by inputting biomass and recovering it as a liquid bio-crude.

To this end, the rapid pyrolysis system for bio-crude production of the present invention includes a biomass silo 100 for storing biomass, a screw feeder 110 for biomass input that quantitatively supplies biomass to the rapid pyrolysis reactor, and biomass. A biomass rapid pyrolysis reactor 120 for rapid pyrolysis, a cyclone 130 for recovering char, a bio-crude condenser 140 for recovering the rapid pyrolysis reaction product of bio-oil as bio-crude, and an oil mist component and tar in a liquid phase. It comprises an electric precipitator 150 for recovering the bio crude oil.

The biomass silo 100 serves to store biomass in order to input biomass into a rapid pyrolysis reactor in a biocrude production system.

The screw feeder 110 for biomass input is an input device for quantitatively inputting biomass stored in the biomass silo 100 into the rapid pyrolysis reactor 120, and is driven using a motor in the form of a screw and provides quantitative supply. For this purpose, it is generally operated in two stages.

The biomass rapid pyrolysis reactor 120 is a device that rapidly pyrolyzes biomass supplied through the biomass input screw feeder 110 and decomposes it into tar, biochar, and non-condensable gas.

The biomass rapid pyrolysis reactor 120 can be used in various types, such as a fluidized bed reactor, a vortex reactor, a rotating cone reactor, and a screw reactor, and is mainly a fluidized bed reactor for active heat transfer between gas and solid. Is used.

In the present invention, the reactor is not specified, but the reaction process will be described using a fluidized bed reactor as an example.

The fluidized bed reactor is a circular column type rapid pyrolysis reactor that has a gas distribution plate at the bottom in a circular column shape and rapidly pyrolyzes biomass using a flow sand. The biomass supplied to the biomass supply device 100 is It is a composition that rapidly decomposes through mixing.

For example, in a fluidized bed reactor, biomass is pyrolyzed and gasified, and it is a member that rapidly pyrolyzes biomass using a fluidized medium. It is an apparatus that generates a pyrolysis gas containing bio oil from the biomass and supplies it to the cyclone 130 when the inside and outside are heated to cause a rapid pyrolysis reaction in the fluidized bed reactor and the biomass is rapidly pyrolyzed.

In addition, nitrogen may be supplied to the biomass supply device 100 and the biomass rapid pyrolysis reactor 120 from the nitrogen (N ₂ ) supply device.

Such a bio-oil condenser can be configured through various processes since it is necessary to condense the bio-oil from the pyrolysis gas.

The pyrolysis gas supplied from the bio-oil condenser 140 passes through a filter before being supplied to the electrostatic precipitator 150, thereby removing dust in the gas entering the electrostatic precipitator 150 in advance. It is possible to increase the lifespan and to increase the quality of the bio-oil produced by the electrostatic precipitator 150.

Such a filter is located in front of the electrostatic precipitator 150 to remove dust in the gas entering the electrostatic precipitator 150 in advance, and the filter is installed at an appropriate position in the bio-oil recovery unit (cyclone to electrostatic precipitator) to recover bio-oil. It can be configured to reduce the negative load and produce high-quality bio-oil.

The electrostatic precipitator 150 recovers oil mist components and tar that were not recovered from the bio-crude condenser 140 as liquid bio-crude by using electrostatic force from the pyrolysis gas from which some dust was removed while passing through a filter (not shown). And non-condensable gas (Non condensable gas) is a device that discharges to the top of the electric precipitator 150.

That is, the electrostatic precipitator 150 extracts bio-oil again from pyrolysis gas that has not been condensed in the bio-oil condenser.

The electrostatic precipitator 150 can be manufactured in a configuration containing various processes if bio-oil can be recovered by a method of collecting dust and oil mist.

When steam is used as an oxidizing agent in the bio-crude gasification reactor 170, it is possible to generate high-quality synthetic gas.

Syngas generated through the gasification reaction in the bio-crude gasification reactor 170 is stored in the syngas storage tank.

Meanwhile, the syngas stored in the syngas storage tank may be finally discharged as reforming gas through a catalytic reaction and dust collection process.

The char combustor 180 may operate as a pure oxygen combustion energy recovery device. In other words, the crude bio-char generated in the gasification combustion pure oxygen, control the CO ₂ generated by post-combustion level may be to supply the high-concentration CO _2.

This high-concentration CO ₂ is mixed with the non-condensed gas of the electrostatic precipitator, which is a thermal decomposition product, and when recycled to the bio-oil condenser, the amount of CO ₂ is adjusted. It affects the gas-solid mixing and heat transfer, and finally can accelerate the reaction.

The cyclone 132 is a dust collecting device capable of recovering dust and solid particles mixed with gas by centrifugal force and gravity, and collects the ash generated from the char combustor 180 and transfers it to the ash collection tank 200 to be collected. It works.

When steam is used as an oxidizing agent in the gasification reaction, since it is possible to generate high-quality synthetic gas, steam is supplied to the bio-crude gasification reactor 170.

As described above, the heat exchanger or steam generator 190 uses the high-temperature exhaust gas generated from the char combustor 180 as an energy source for generating heat during steam generation.

Therefore, the heat exchanger or steam generator 190 uses the high-temperature exhaust gas provided from the char combustor 180 as an energy source when generating steam, and the generated steam is supplied to the bio-crude gasification reactor 170, The char generated in the gasification process of the bio-crude gasification reactor 170 is burned in the char combustor 180, and the high-temperature exhaust gas generated at this time is supplied to the heat exchanger or the steam generator 190 again, thereby efficiently saving energy. It can be used.
