Description
Technical field
The invention belongs to natural gas technical field, more particularly to a kind of natural gas accelerant.
Background technology
Natural gas is widely used in national economy every field as a kind of clean energy resource.Natural gas is made
There is pollution-free, environmental protection for a kind of clean fuel.But ignition temperature typically exists natural gas in use
2000 DEG C or so, its combustion heat value is not high.In mechanical cutting processes, acetylene is generally used as cutting gas.But acetylene is
A kind of product of high energy consumption, during Metal Cutting, presence pollution weight, big power consumption, high cost, cut quality are poor, explosive inflammable
The shortcomings of, therefore the succedaneum for seeking acetylene in the field becomes already and knows together in the industry.In recent years with methane as key component
Natural gas has obvious advantage, and the burning of natural gas at aspects such as high efficiency of energy utilization, environmental protection as Metal Cutting gas
Temperature, combustion heat value are low, and its range of application is restricted.Therefore it is within the contemplation of the invention that providing a kind of natural gas accelerant, Neng Gouyou
Effect changes the combustion mechanism of natural gas, significantly improves the ignition temperature and calorific value of natural gas, reduces natural gas as clean fuel
Specific consumption, while by natural gas applications in Metal Cutting field.
The content of the invention
It is an object of the invention to provide a kind of natural gas accelerant, effectively improves the ignition temperature and calorific value of natural gas,
Natural gas is reduced as the unit consumption of clean fuel, and Metal Cutting field is applied to using natural gas as the succedaneum of acetylene.
For achieving the above object, the technical solution used in the present invention is as follows：
A kind of natural gas accelerant, described accelerant are made up of following mass fraction：Organically-modified hectorite supported catalyst
Agent 5%-10%, acetonitrile 20%-40%, petroleum ether 30%-50%, ketenes 1%-2%, bromomethyl acylbromide 1%-2%, ethanol 10%-30%, mistake
Potassium sulfate 1%-2%.
It is further preferred that described accelerant is made up of following mass fraction：Organically-modified lithium soap stone-type load is urged
Agent 8%, acetonitrile 30%, petroleum ether 40%, ketenes 1%, bromomethyl acylbromide 1%, ethanol 28%, potassium peroxydisulfate 2%.
It is further preferred that described accelerant is made up of following mass fraction：Organically-modified lithium soap stone-type load is urged

It is further preferred that the organically-modified lithium soap stone-type supported catalyst is with trioctahedron and tetrahedral structure
Nano lamellar hectorite section bar material based on, by Co3O4Carry out it is pillared after, then entered using 18-amine. or cetyl pyridinium
Row is organically-modified to be obtained.
It is further preferred that addition of the accelerant in natural gas is 6-10g/Nm3。
Existing natural gas accelerant mainly has heterogeneous catalytic oxidation mechanism, this kind of catalytic machine to the combustion mechanism of natural gas
The additive of reason with rare earth element class additive as representative, the outer-shell electron of the main reason rare earth atoms of such additive
Property, it is combustion-supporting to realize the heterogeneous catalysiss to natural gas during combustion of natural gas, so as to improve natural gas
Flame temperature and calorific value.
Natural gas accelerant in the present invention, is capable of achieving the multi-phase catalytic oxidation to combustion of natural gas in use
With the synergism of free yl induction catalytic reaction, so as to the ignition temperature and calorific value of natural gas can be effectively improved, in accelerant
Organically-modified lithium soap stone-type supported catalyst, the Co for being loaded2O3It is capable of achieving to act on the heterogeneous catalytic oxidation in combustion process.
In accelerant, ketenes, bromomethyl acylbromide can realize the homogeneous freedom during combustion of natural gas under the initiation of potassium peroxydisulfate
Base reacts.
Existing terres rares natural gas additive, typically can not, uniform system stable with natural gas, typically using
In journey, such additive is mixed to improve the calorific value of natural gas by metering with natural gas.
The additive of existing terres rares is poor with the intersolubility of natural gas, can not with natural gas in natural gas storage device
Form stable heterogeneous system.Such additive can only pass through metering device during natural gas motorcar and mixing arrangement adds
Use.Such additive storage device that must be individually equipped with additive higher to the requirement using equipment, metering device and mixed
Attach together and put.Therefore such additive is comparatively laborious using process.
Natural gas accelerant in the present invention, due to the special tridimensional network of lithium soap stone-type supported catalyst, at which
After forming aerosol, it is possible to achieve with natural gas and the stable dispersion of accelerant other components.Accelerant in use,
Without being separately provided storage, metering and mixing device, only additive need to be added by dispersing apparatus during natural gas charging
Enter in steel cylinder, only need a natural gas gas storage cylinder in use.Therefore the accelerant in the present invention will to equipment
Ask low, it is easy using process.
Compared with existing additive, the multiphase that the natural gas accelerant in the present invention can be stable with natural gas adsorption
Dispersed system.Lithium soap stone-type supported catalyst using 18-amine. or cetyl pyridinium after organically-modified, can be preferable
Be distributed in the mixed solution of acetonitrile and petroleum ether, form transparent, homogeneous liquid.Initiator mistake can be realized using ethanol
Potassium sulfate is completely dissolved and disperses.Therefore acetonitrile, petroleum ether and alcohol mixed solution are adopted in additive of the present invention as molten
Agent, can be good at dissolving lithium soap stone-type catalyst and potassium peroxydisulfate and forming mutually solution system.
Natural gas accelerant in the present invention is present with homogeneous liquid form, and the accelerant passes through aerosol generating device,
Stable heterogeneous system can be formed in steel cylinder with natural gas.As, in lithium soap stone-type supported catalyst, matrix hectorite has
There is nano lamellar three-dimensional net structure, the material such as natural gas and ketenes, bromomethyl acylbromide in mixed system can be fine
Be dispersed in above-mentioned three-dimensional net structure, realize mixing for natural gas and additive, cause the natural gas in the present invention
