Description
Technical field
The present invention relates to a kind of novel environment friendly high burning-value straw coal and preparation method thereof.
Background technology
The annual yield of biomass in China is very big, but the utilization of biomass is again especially small, wherein national annual 90 %
Stalk is directly burned, filled or is directly discarded in farmland and carries out biodegradation, and this part resource is wasted.
The energy is the basis of developing national economy.At present, as social development progress, energy resource consumption are bigger.Due to fossil
Fuel wretched insufficiency, while environmental pollution is big, and also fossil fuel is influenceed by international situation, regional conflict, and supply is becoming tight day.
Many oil, coal, natural gas producing country control international market, to strengthen national influence power as strategic arms.China's coal storage
Amount only accounts for 2 % of world saving, with substantial amounts of exploitation, the clue not planned a successor, and the energy peace of serious threat to China
Entirely.In order to break away from the dependence to fossil fuel, promote national economy sustainable development；Country pays much attention to the research of bio-fuel
With development, regenerative resource is included to national energy development strategy, is advantageous to the energy leather in fossil fuel epoch behind China
Life.
In the stalk of straw coal generally use after being pulverized plus water carries out compacting and formed, the deficiency of so manufactured straw coal
It is mainly reflected in：Not easy-formation, storage, because stalk is usually agricultural crop straw, leaf, deadwood, sawdust, weeds etc., raw material
Middle water content is larger, easy modification after manufactured straw coal after simple crushing, while apt to deteriorate in outdoor, is unfavorable for storing；
Burn insufficient, because water content itself is larger in raw material, a certain amount of water is added in manufacturing process, causes the combustion of straw coal
Burn insufficient, energy loss is larger, while it is insufficient to burn, and is not reaching to the value made full use of.
The content of the invention
The technical problems to be solved by the invention are to provide environmentally friendly high burning-value stalk, and its discharge capacity is low, clean environment firendly, simultaneously
Combustion rate is high, sulfur-fixing rate is high.
The present invention is achieved through the following technical solutions：
A kind of novel environment friendly high burning-value straw coal, includes following components：It is stalk, clinker, accelerating agent, oxide, sulphur-fixing agent, organic
Ester.

Sour methyl esters.
A kind of novel environment friendly high burning-value straw coal, also comprising Boratex-ATBC.
The parts by weight of described Boratex-ATBC are 1-5.
The preparation method of Boratex-ATBC is as follows：
In 150 mL three-necked flasks, 1 mmol citric acids, 5 mmol n-butanols and 0.1 mmol Catalyzed by p-Toluenesulfonic Acid are added
Agent, load onto water knockout drum and backflow cooling device, the lower electric furnace heating of agitator stirring（120 ℃）, backflow is reacted under fluidized state
Divide water, stop reaction, cooled and filtered recovery catalyst, sampling, with the acid of standard alkali solution measure mixture after moisture is complete
Value, press the esterification yield of column count reaction：Esterification yield（%）=（Acid number before 1- acid numbers/reaction）The % of X 100, after calculating ester content
Reactant mixture distills out unreacted n-butanol at normal temperatures, then changes into vacuum distillation, collects 170-172 DEG C, and 133
Pa cut, obtains pale yellow oily liquid.
By it is above-mentioned to pale yellow oily liquid add flask in, add 40 mL toluene, 0.05 mmol boron thereto
Sour sodium and 0.01 mmol butters of tin, 3 h are reacted at 80 DEG C, mixing speed is 200 rpm, after reaction terminates, under normal temperature
Cooling, both.
A kind of preparation method of novel environment friendly high burning-value straw coal, it is comprised the steps of：
1) stalk is crushed in pulverizer, reaches 40-100 mesh；
2) stalk powder that crushing obtains is put into dryer and dried, it is ensured that stalk water content is between 5-10 %；
3) the obtained stalk of drying is taken out, clinker, accelerating agent are first added in 40-60 DEG C of blender, oxide, sulphur-fixing agent, is had
Machine ester, 3-6 h are uniformly mixed, obtain mixed-powder；
4) by 3）Obtained mixed-powder is transferred in blender, and adds absolute ethyl alcohol 60-100 parts, is stirred at 80-120 DEG C
