In this study, the self-heating tendency of Tavşanlı (Turkey) coal was investigated by the apparatus of thermal analysis. TG-DTG and DSC-DDSC plots obtained at air atmosphere from 25 to 800 °C were used to determine the self-heating temperature (T sh) and the combustion behavior of coal. The self-heating temperature changes versus the particle sizes of coal and heating rates were examined . Also, kinetic parameters of the main combustion region were obtained in the temperature range of 25 to 800 °C at different heating rates (1, 2.5, 5, and 10 °C min–1) under nonisothermal heating conditions at air atmosphere. The activation energy, pre-exponential factor, and reaction mechanism were calculated by using KAS, FWO, Coats–Redfern, and Master-Plot methods. It was understood that the oxidation process of coal was controlled by the first order [F1: −ln (1 – α)] mechanism.

The synthesis of copper oxide (CuO) via the thermal decomposition of copper (II) acetate monohydrate (Cu(CH3COO)2.H2O) in air atmosphere was investigated at TG-DTG/DSC apparatus with the heating rate of 10°C min -1 under non-isothermal conditions from 25 to 900°C. It was seen from TG-DTG/DSC analyzes that the thermal decomposition process consists of three main steps (two mass-loss regions and a tiny mass-gain region). The obtained products at 200, 300, 400°C temperatures were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Energy disperse spectroscopy (EDS) analysis. The XRD results show that the CuO nanoparticles having the monoclinic crystal structure. The SEM images showed that CuO nanoparticles were spherical in shape. The size of CuO nanoparticles decreased with an increase in annealing temperature. BAKIR ASETAT MONOHİDRATIN (Cu(CH3COO)2.H2O) TERMAL BOZUNMASINDAN BAKIR OKSİT (CuO) SENTEZİ ÖZBakır asetat monohidratın (Cu(CH3COO)2.H2O) termal bozunma yolu ile bakır oksit (CuO) sentezi hava ortamında izotermal olmayan şartlar altında 10°C dak -1 'lik ısıtma hızıyla TG-DTG/DSC cihazında incelendi. 25°C'den 900°C'ye kadar termal bozunma prosesinin üç adımda gerçekleştiği görüldü (iki kütle kayıp bölgesi ve bir küçük kütle kazanç bölgesi). 200, 300, 400°C sıcaklıklarda elde edilen ürünler X-ışını kırınımı (XRD), Fourier dönüşümü kızılötesi spektroskopisi (FTIR), Taramalı elektron mikroskobu (SEM), ve Enerji dağıtıcı spektroskopisi (EDS) analizleri ile karakterize edildi. XRD sonuçları CuO nanopartiküllerin monoklinik kristal yapıya sahip olduğunu göstermektedir. SEM görüntüleri CuO nanopartiküllerinin şekil olarak küresel olduğunu göstermektedir. CuO nanopartiküllerin boyutu, tavlama sıcaklığındaki bir artışla azaldı.Anahtar kelimeler: Bakır asetat monohidrat, bakır oksit, termal bozunma
