Micro carbon residue, commonly known as "MCR" is a laboratory test used to determine the amount of carbonaceous residue formed after evaporation and pyrolysis of petroleum materials under certain conditions.
The ash content can be defined as the gravimetrically determined residue after ignition at a defined temperature, in a sample, in percent (weight / weight dry matter of sample). In the determination, a sample is weighed in a heat-resistant crucible, dried at 105±2 °C, and ignited in a muffle furnace at 525±25 °C.
A carbon with a low soluble ash content should be used for marine, freshwater fish and reef tanks to avoid heavy metal poisoning and excess plant/algal growth. ASTM (D2866 Standard Method test) is used to determine the ash content of activated carbon.
When researchers in the Boulder study surveyed nearby residents, they reported symptoms related to the smoke and ash including headaches, coughing, sneezing, sore throat and watery eyes even six ...
Before and after photos of the deadly wildfires in the Los Angeles area have sent tens of thousands scrambling for safety and decimated neighborhoods.
This removes high-ash value particle and increases the saleability of the coal as well as its energy content per unit volume. Thus, coals must be subjected to a float-sink test in the laboratory, which will determine the optimum particle size for washing, the density of the wash liquid required to remove the maximum ash value with the minimum work.
