The graphitisation process, a major part of synthetic graphite manufacture, requires very high temperatures (above 2,300 o C) and consumes large amounts of energy (more than 12,000 kwh/t). In China, the graphitisation step is often carried out separately from the rest of the synthetic graphite manufacturing process at independent facilities.
Synthetic graphite was synthesized from oil palm trunk chip in controlled heating condition or pyrolysis process. The heating rate (5 °/min, 10 °/min and 20 °/min) were varied whilst the heating temperature at 800 °C was fixed.
The synthetic graphite market is expected to register a CAGR of 4.17% during the forecast period, 2019-2024. Asia-Pacific dominated the market across the globe, with the largest consumption seen ...
For synthetic graphite production there are NOx, SOx, and PM10 emissions, due to sulphur, nitrogen, and ash impurities in the coal tar pitch and pet coke, which burn during the carbonation process 10. The energy intensive nature of this process also means that emissions are sensitive to the electricity source powering the process.
