How to analyze coal tar?
Thread Content
What instruments are needed for coal tar analysis? What are the analysis parameters? I’m new to this; I can’t find the spoon. Thank you for your help
Reply from a user on the network: GB 3701-1989 \"Coal Tar\" came into effect on March 1, 1989; it was later replaced by YB/T 5075-1993, which is currently in force. GB 3702-1983 \"Method for Determining the Density of Coal Tar\" was implemented on May 1, 1984, and was later revised to YB/T 5076-1993 ； YB/T 5076-1993 was revoked on June 1, 1995, and replaced by GB/T 15243-1994 \"Method for determining the density of coking viscous oil products\" ； GB/T 15243-1994 will be repealed on 2008-11-01, and replaced by GB/T 2281-2008 \"Test methods for density of coking oil products\". GB 3703-1983 \"Method for Determining Toluenesoluble Matter in Coal Tar\" was implemented on May 1, 1984, and was later revised to YB/T 5077-1993 ； YB/T 5077-1993 was repealed on May 1, 1998, and replaced by GB/T 2292-1997 \"Determination of toluene-insoluble matter content in coking products\". GB 3704-1983 \"Method for Determining Naphthalene Content in Coal Tar by Gas Chromatography\" was implemented on May 1, 1984, and was later revised to YB/T 5078-1993 ； YB/T 5078-1993 was repealed on January 1, 2002, and replaced by YB/T 5078-2001 \"Gas chromatographic method for the determination of naphthalene content in coal tar\"
Here is another link that contains complete answers; I recommend you take a look at it. The post written by moderator Canghai on how to search for the content you need will be useful to you: http://bbs.hcbbs.com/viewthread.php?tid=378010&highlight=%C3%BA%BD%B9%D3%CD
Thank you, the person above; I need these standards as well. .
It’s a very common problem! You’ll get the results you want by searching on Baidu! Coal tar analysis is a very common type of analysis, which includes measurements such as density, viscosity, toluene-insoluble matter, n-hexane-insoluble matter, ash content, and moisture content!
The national standards for coal quality analysis specify 18 testing indicators, including industrial analysis (total moisture, moisture, ash, volatile matter, fixed carbon), elemental analysis (carbon, hydrogen, nitrogen, total sulfur, oxygen), and technical analysis (calorific value, dust suspension test, Rogowski index, caking index, gum layer index, low-temperature dry distillation test with aluminum crucible, slugging tendency, reactivity to carbon dioxide, mechanical strength).
Thank you! RSFX-MZ3.2. This software can perform coal quality analysis; it’s a really good tool!
