Detailed description:
一.The introduction of the gas:
Synthetic fuels is a kind of hydrocarbon combustible gas given priority with hydrogen gas, which is burning safe and with high efficiency, non-toxic tasteless, and it is a new kind of green and clean energy. Synthetic fuels has many advantages such as no harm to the environment, rich raw material resources, and a low cost price. Products can be widely used in power generation, industrial, civil and motor vehicles and other fields. It is a green energy which is benefit for the mankind.
The use of hydrogen energy is a high-tech project on energy and environmental protection, which has been studying and discussing by scientists around the world for many years, and hope to get a breakthrough. The successful development of synthetic fuels has opened up a new way for effective utilization of hydrogen energy, which is a landmark multidisciplinary and high-tech achievement.
Hydrogen is the chemical energy of the hydrogen. Hydrogen mainly takes the form of combining state on earth, which is the most widely distributed in the universe, and constitutes the 75% of the mass of the universe. Because hydrogen must be out from hydrogen material, such as the water and fossil fuels, so it is the secondary energy sources. The hydrogen has the following main advantages: high combustion heat value, and after burning, the heat of per kilogram hydrogen is about three times as much as gasoline, 3.9 times of alcohol, and 4.5 times of coke. The product of combustion is water, which is the cleanest energy in the world. Rich in natural resources, and the hydrogen can be made from water, and water is the most abundant resources on the earth. At present, the technology of the hydrogen in the United States, Japan, the European Union and other countries and regions has stepped into the stage of system implementation. The main components of the synthesis of hydrogen gas is CO and H2, and water (including all kinds of rivers, industrial and civil sewage) is used as raw material, made from pyrolysis process in the condition of low temperature. It can take the place of existing fuel(fuel gas)and widely used in industry, automobile, civil and other areas which need fuel for energy. The cost is far superior to other methods of hydrogen production. So, the synthesis of hydrogen gas has always been considered as the ultimate solution for the use of hydrogen, and solving the crisis of human energy in the future.
Methods for preparation of synthesis gas is that under certain pressure and temperature, material liquid mixture is heated by high temperature plasma arc flow produced between electrodes. Under the effect of plasma arc in high temperature, the material liquid mixture take place fragmentation reaction, resulting in combustible mixed gas. I.e., the electrode (arc) + material liquid mixture →combustible mixed gas.
二.The characteristics of fuel gas:
The production method of synthetic fuels is very simple. Introducing the water into the special device and cracking with special graphite electrode rod can generate the combustible mixture gas.
Production raw materials of synthetic fuel are mainly water and graphite electrode. All kinds of water resources can be used, such as people's daily life water, water (reclaimed water), river water, sea water, or inorganic waste water which has been polluted, etc., are all for it. Sewage after electrolytic reaction, it can also have the effect of purification treatment of the water quality. In the production process of synthetic fuels, a small amount of graphite electrode is needed. The source is also very wide, mainly from the graphite ore.
Basic properties of synthetic fuel:
Synthetic fuel is a composite gas fuel combined with hydrogen and carbon monoxide. The density in standard state is 0.66 g/l and average relative molecular weight is 16.1 g/mol. Synthetic fuel is the known lighter gas without color and taste, which is given priority to hydrogen, also contains carbon monoxide, acetylene, methane and other inert gases, and can be stored, transported and used under the atmospheric pressure.
Synthetic fuel has high burning value and high flash point. After combustion, the emission is water, and it cannot pollute the environment after volatilization. On the contrary, it can also improve the atmospheric circulation, and increase the humidity of the air. So, it is the most ideal clean fuel to replace the traditional fuel.
Synthetic fuel has a high burning calorific value. Testing results showed that synthetic fuels has higher calorific value. The ingredients are in the following table:
Name Results unit Test results
Hydrogen(V/V)% 52.821
Carbon monoxide(V/V)% 42.818
Carbon dioxide(V/V)% 3.703
Methane(V/V)% 0.128
Ethane(V/V)% 0.0017
Ethylene(V/V)% 0.0457
Acetylene(V/V)% 0.0714
Good safety: Synthetic fuel contains a variety of inert gas which can protect the stability of surface electronic of hydrogen molecules to ensure the safety of hydrogen combustion. Its security is better than that of liquefied petroleum gas, natural gas and coal gas, etc.
Non-toxic tasteless, clean, no pollution, and does not produce chemicals with the greenhouse effect.
Compare synthesis gas with other fuels:
Project Unit Synthesis gas Gasoline Natural gas
hydrocarbons (mg/km) 0.026 0.234 0.380
Carbon monoxide (mg/km) 0.262 1.965 5.4947
Nitrogen oxides (mg/km) 0.281 0.247 0.732
Carbon dioxide (mg/km) 235 458 464
Oxygen (mg/km) 9%-12% 0.5%-0.7% 0.5%-0.7%
三.The usage of fuel gas:
As a new type of clean energy, synthetic fuels can take the place of the liquefied petroleum gas, natural gas, coal gas, petrol and diesel, which can be widely used.
Civil and commercial fuel:
Civilian fuel is mainly used in household cooking, heating, and water heater, etc. Stoves usage show that the gas cookers modified slightly after using synthetic fuel, combustion temperature is high, and the flame is blue and brilliant. When the flame control at a minimum, black smoke can never appear, etc. No matter how long it is burning indoor, there is no peculiar smell and the feeling of choking. Used for cooking, the expansion area of temperature at the bottom of the pot is large, and the oil temperature is high which can realize fast cooking.
Commercial fuel is mainly used as cooking and heating in hotels, restaurants, factories, hospitals, schools and other heat sources.
Motor vehicle fuel: Synthetic fuel is very ideal used in motor vehicles.
Car using synthetic fuels showed that modified car after using natural gas can be directly started after filling synthetic fuels, which is not like natural gas burning, it needs gasoline to start first, and after it is up to 3000r/min, it can switch automatically. Driving feel is powerful, and the emission of tail gas is water vapor and water droplets.
Industrial fuel:
Synthetic fuels used as heat source in industry application is very wide.
To generate electricity: Using synthetic fuel to generate power shows that using synthetic fuel in gasoline generators has good power, stable working state of generators, no voltage fluctuations and clean emissions.
Cutting: Using synthetic fuel to cut steel case shows that cutting plates with synthetic hydrogen fuel directly, the temperature of fire is as high as 1800 ℃. Flat has no residue, and it can cut any thickness of the steel plate less than 10 centimeters, without harmful gas to release.
The boiler fuel.
Metal smelting.
Heat treatment.
Dry processing etc.
Synthetic fuels can be mixed used with natural gas and other fuels. Experimental study at home and abroad showed that the hydrogen blending into the natural gas used as vehicle fuel, the maximum explosion pressure of engine can be increased. It has improved some performance of natural gas engine, and can reduce 50% of the exhaust emissions. Applications in civil burner can improve its combustion characteristic, improve fire-off limits of the fuel gas and generation limits of the carbon monoxide, reducing the degree of appearing yellow-smoking. Low ignition energy improves the heating efficiency of the burner.
The production technologies and equipment of synthetic fuel can be used to deal with the sewage (waste water).
Dealing with sewage (waste water) is a big problem in the processing of factory production. In general, producing the sewage (waste water) into synthetic fuel can achieve zero discharge of sewage (waste water), and create economic benefits again. Therefore, the production technology and equipment of synthetic fuel to deal with sewage (waste water) has a broad prospects.
