Abstract
The high- energy fuel includes in its components methyl ether, methane, ethane or ethylene, propane or propylene, butane or butene, pentane and additive. The additives includes ferrocene as anti-explosion smoke-eliminating agent; carbon disulfide as combustion promoter; isopropyl alcohol, acetone and methyl alcohol as diluent solvent; polyoxyethylene as antistatic agent; magnesium and aluminium powder as temperature increasing agent; triethanolamine as suspending agent; and off odour agent. The production process of the fuel is mixing the said components and has no environmental pollution. The fuel is safe and low in cost and can result in cutting and welding quality superior to that of acetylene.
Description
The present invention relates to based on the carbonaceous fuel of the liquefaction hydrocarbon gas and the preparation method of additive thereof.Additive is the synergy component of this fuel.
Acetylene gas is used for the existing nearly 200 years history of industrial production, because the characteristic of acetylene chemistry character causes its inborn defective:
1, contaminate environment: acetylene gas is calcium carbide (carbide of calcium CaC
2) add the product of water, and contain a small amount of p and s in the calcium carbide, therefore, in the reaction process with phosphuret-(t)ed hydrogen (H
3P) and hydrogen sulfide (H
2S) etc. obnoxious flavour produces.In addition, also have a small amount of calcium cyanamide to produce in the lime mud.Above-mentioned by product is polluted source, soil and air all.
2, consumes energy: calcium carbide is to smelt under 3000 ℃ high temperature with coke and unslaked lime to form, so need a large amount of electric energy of consumption, refines one ton of calcium carbide, needs power consumption 3600 degree, is one of typical electric-tiger.The production of calcium carbide needs altogether through six Energy conversion.
3, easily tempering, dangerous: because the acetylene gas combustionvelocity is fast, per second reaches 7.60 meters, the gas velocity when being higher than welding.Therefore easily tempering.The security incident that causes thus is countless.In addition, extremely unstable because acetylene gas character is active, be higher than 1.5kg/cm at pressure
2In time, just easily set off an explosion, thus acetylene gas directly filling bottle use, and need toward steel cylinder in, add carrier in advance, again the acetylene gas compression is dissolved in the carrier, so in the industry present use be called dissolved acetylene.In a word, acetylene gas is a kind of industrial combustion gas that is absolutely unsafe.
In recent years, have some both at home and abroad and come into the market for the acetylene Cutting Gas, its type and relative merits are as follows:
1, with the high-pure propylene be the Cutting Gas of raw material, advantage is that temperature of combustion is higher, and shortcoming is that loading pressure is big, and the design pressure of container is had relatively high expectations, and production cost is higher.
2, with propane be the Cutting Gas of raw material, advantage is that saturation vapour pressure force rate propylene is low slightly, and shortcoming is that combustionvelocity is slow, and temperature is on the low side, and warm up time is long.
3, with the liquefied petroleum gas (LPG) be the Cutting Gas of raw material, advantage is that cost is low, and shortcoming is that temperature is on the low side, and winter, result of use was poor during low temperature, and oxygen consumption is large-minded.
4, above combustion gas all is not suitable for welding that is replaced acetylene gas fully.
In addition, number of patent application 94111279.9 alleged employing carbon containing 5 (C
5) the above organism 91-96% of hydrocarbon, and add small amount of acetone, sodium hydroxide, sulfuric acid, potassium permanganate, dimethylbenzene etc. and make additive and constitute stimulated acetylene fuel, because C
5For there not being the raw material of pressure, implement by this method, can't gasify, under normal condition, can not obtain reliable Cutting Gas and welding gas.
The object of the present invention is to provide that a kind of high-temperature, high heating value, free from environmental pollution, moderate pressure, security are good, not tempering, lower-cost be main component with carbonaceous fuel, mix novel high-energy cutting-welding gas with part oil liquefied gas and additive and preparation method thereof again.
Major scheme of the present invention is:, propane rare based on methane, ethane, second, third rare, the methyl ether, mix with the part oil liquefied gas according to pressure condition, under the effect of additive, the combustionvelocity of above-mentioned single component or mixed composition is accelerated, temperature of combustion is improved, a series of combustioncharacteristicss improve, thereby obtain a kind of cutting that both had been suitable for, and are suitable for the infant industry cutting-welding gas that welds again.
Its novel gas composed as follows:
Dme 0～98%
Methane 0～98%
