Q: What is the density of coke?: There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.

Q: What is the use of petroleum coke: Petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining

Q: Coke is how to make it? What is the use?: Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.

Q: What is the reasonable ratio of coal to coke: There are lignite, bituminous coal, anthracite, semi anthracite these categories. Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage.

Q: What are the indicators of first grade coke and the two grade coke?: The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)

Q: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?: Two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile < 1.9%; all 6% "0.7%" water; sulfur;

Q: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.: There is no containing copper sulfate solution with tin. Because the copper iron can be displaced from the salt solution in their description, copper and iron;To sum up, we can know that C, Al, Cu, Fe four elements of the order of activity is Al > C > Fe > Cu;The answer is: Al > C > Fe > Cu.

Q: Coke and coal is one thing: How coal is formedCoal has been hailed as the black gold, the food industry, it is one of the main sources of energy used in the human world since eighteenth Century. Although its important position has been replaced by oil, but in the future for a long period of time, due to the exhaustion of petroleum, inevitable decline, but because of the huge reserves of coal, coupled with the rapid development of science and technology, the new technology of coal gasification is becoming more mature and widely used, coal will become one of the human production life cannot substitute energy.

Q: 8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.: The structure of benzene and toluene is similar, and the molecular composition is different from that of a CH2 atom cluster, which is called homologous;(5) the number of chloro compounds in the hydrogen molecule is equal to the number of hydrogen atoms in different environments, and toluene has four kinds of hydrogen atoms in different environments: methyl group on the top, the benzene ring on the top of the 3 species, and so on, there are 4 kinds of chlorine compounds in toluene,

Q: What are the quality indicators of coke: Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke.
