Q:Other related to coal oil
According to expert estimates, when the price of crude oil in more than 28 U.S. dollars, coal oil in the economy is more cost-effective; below this price, coal oil is not worthwhile. Therefore, in the middle of the 80s to the middle of the 90s, international oil prices have been at a low level, coal oil will naturally not be taken seriously. However, the technology has been quite mature, can be said to have a ready pen, as long as the needs of the market, can undertake large-scale industrialization. Until the last two years, international oil prices continue to rise, coal oil re put on the agenda by countries. The United States began to engage in indirect liquefaction last year, France, Italy began to cooperate in R & D. But from the start of the project to start the construction of at least 5 years of preparation time, and oil price changes frequently, while low, people tend to make decisions about the response lag.
Q:The nature and classification of coal gangue?The classification and properties of coal gangue for writing papers
1, according to the sources classification according to the coal gangue output that can be divided into the source of coal gangue gangue, gangue, coal roadway rock gangue, gangue gangue and stripping hand selected, some of the coal gangue as a source according to the classification of(1) the gangue discharged from the raw coal washing process is called the washing waste. The concentration of the washing waste is concentrated, the grain size is fine, the calorific value is higher, the clay mineral content is high, the content of carbon, sulfur and iron is generally higher than other kinds of gangue(2) coal gangue in the coal mine roadway tunneling process, all along the seam mining, excavation engineering from coal gangue, coal gangue, coal roadway called Xiang Gan is mainly composed of mining coal seam roof and floor rock, interlayer composition, carbon content and calorific value often containing certain, sometimes containing CO with mineral resources.(3) the waste rock roadway in coal mine construction and rock tunnel excavation process, all along the seam tunnelling emissions produced by coal gangue, gangue rock roadway rock roadway. Collectively, gangue containing rock complex types, discharge is more concentrated, its low carbon or carbon, so no calorific value.
Q:How long the activated carbon tank. It will fail, there will be any fault
Evaporative emission control system has an active carbon storage tank, fuel vapor from the fuel tank from the "TANK" mark into the carbon canister. Liquid fuel entering the carbon canister is stored in a tank at the bottom of the canister to protect the active carbon carbon from the top of the canister, while the fuel vapor is absorbed by the active carbon. When the engine is at idle speed above the running environment, air enters the canister through the upper air pipe, the fuel vapor was washed out from the air blowing carbon, and mixed into mixed gas is sucked into the intake manifold.
Q:Tank filter inside the activated carbon for a long time will fade it?
The general bath, put on activated carbon adsorption of residual drugs, two days after take out, not more than a week, placed in the top of the filter can be.
Q:Well log interpretation
The coal seam has the obvious characteristic in the well logging curve: "four high" characteristic: the resistivity is high, and the change scope is big, the sound wave time difference is big, the transmission speed is slow, the compensation neutron is big, the well diameter enlargement is big
Q:What are the main equipment of coal chemical industry?
EM+PC (Design - Procurement - construction general contracting management), EP (engineering procurement contract), PC (total construction contract, procurement) and PMC (project management contract) and other project management mode to undertake large-scale coal chemical plant construction.
Q:What is the difference between raw coal and standard coal?
2 standard coal (Standard coal):Energy containing various fuels is different, such as 1 tons of coal of about 7560 kwh, 1 tons of coal is about 2200 kwh, 1 tons of coke for 7790 kilowatt hours, 1 cubic meters of gas for 4.7 kilowatt hours. In order to use convenient, uniform standards, the comparison between the quantity and quality of energy, coal, oil and natural gas are according to a certain proportion of unified converted into standard coal to represent (calorific value of 1 kilograms of standard coal is 29 trillion and 270 billion joules, namely per ton of standard coal is 29270 MJ). The conversion method is:
Q:There are several categories of coal sampling machine
Peat flammability, easy combustion, strong reactivity, low sulfur content, low ash melting point, but lower mechanical strength. Therefore, the use of peat is not high value in industry, it is not suitable for long distance transportation, generally only as a local fuel use. Areas located in the southwest provinces and Zhejiang (West Lake coal).In June 2009, the State Administration of Quality Supervision Inspection and quarantine and the National Standardization Management Committee jointly issued the "national standard" classification of coal Chinese (GB/T 5751-2009), on the basis of dry ash free volatile Vdaf, dry ash free hydrogen bond index G, Hdaf, Y, glial layer maximum thickness of Oaxaca expansion degree B, low rank coal light the rate of P, and ash free calorific value Qgr, MAF 7 classification index, coal will be divided into 14 categories. The lignite, long flame coal, non caking coal and weakly caking coal, 1/ 2caking coal, gas coal, gas coal and 1/3 coking coal, coking coal, lean coal, lean coal, lean coal and anthracite.According to the different classification of the rock structure, can be divided into candle coal, silk carbon, dark coal, bright coal and mirror coal. Contains more than 95% vitrinite for coal, coal surface light, solid structure, containing vitrinite and light for plastid clarain, containing coarse body as dark as coal, with silk silk carbon, formed by many microspores formed for the microsomal cannel.
Q:The basic situation of coal occurrence in coal mining area
(1) the origin of the edge coal. The main reasons for the formation of edge coal are as followsThe arrangement mode of the utility model is that the straight groove and the cutting hole are directly connected to form a cutting edge triangle coal,Is the formation of the edge of the coal artificial factors; two is affected by the fault and geological structure, can not ruleIt is a natural factor for the formation of the edge coal to arrange the complex block of the working face. ThreeThe coal pillar and the coal pillar in the mining area have a certain mining value:
Q:Coal and carbon is one thing, what is the difference?
Chemical composition:The organic matter in coal is high polymer complex organic compounds, mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus and other elements, and more than three carbon, hydrogen and oxygen and total organic matter occupies 95%; inorganic matter in coal also contains carbon, hydrogen, oxygen, sulfur and other elements of a few. Carbon is the most important component in coal, and its content increases with the degree of coalification. The content of carbon in peat is 50% ~ 60%, the lignite is from 60% to 70%, the bituminous coal is from 74% to 92%, and the anthracite is from 90% to 98%. Sulfur in coal is the most harmful chemical component. Coal combustion, in which sulfur generated SO2, corrosion of metal equipment, pollution of the environment. The content of sulfur in coal can be divided into 5 levels: high, greater than 4%; sulfur rich coal, from 2.5% to 4%; sulfur in coal, from 1.5% to 2.5%; low sulfur coal is 1% ~ 1.5%; ultra low sulfur coal, less than or equal to 1%. Sulfur in coal can be divided into two categories: organic sulfur and inorganic sulfur.
