Çay Tesisi Atıklarından Hidrotermal Yöntemle Aktif Karbon Üretimi.

Tea facility waste is the organic waste left over from the tea processed in the factory. Tens of thousands of tons of tea facility waste are consist every year during tea production in factories in the Black Sea Region. In this study, activated carbon has been carried produce by hydrothermal method using tea facility wastes provided from Rize-ÇAYKUR facilities. For this purpose, the samples were processed at different times and temperatures in a hydrothermal device (HTC) both activating agent using and without using an activating agent. SEM, EDX, BET and methylene blue absorption analysis of the obtained samples carried. According to the BET analysis results of the samples obtained from the experiments carried out without using an activating agent, the surface area of the sample processed at 100oC for 8 hours was obtained as 2,13 m²/gr. The BET surface area of the samples activated after hydrothermal carbonization has been detected as 887,41 m²/gr and 874,77 m²/gr, depending on the KOH/Hydrochar ratio. In addition, it was calculated that the extraction efficiencys of the obtained products measured by Ultra-Violet (UV) spectrofotometer in 300 ppm methylene blue absorption experiments reached up to 99%.
