In this article, thermogravimetry (TG/DTG) was used to determine the effect of heating rate on the thermal properties and kinetics of raw and cleaned coal samples from Soma, Tuncbilek, and Afsin Elbistan regions. TG/DTG experiments were carried out at 4 different heating rates (5, 10, 15, and 20degreesC/min). Generally, for all of the samples higher peak and burnout temperatures were measured with an increasing heating rate. Kinetic parameters of the samples were determined using an Arrhenius-type kinetic model, and it was observed that activation energies of all the samples were affected inversely when the heating rate was increased.

Effect of pressure on combustion kinetics of heavy oils Bağcı, Ali Suat (Informa UK Limited, 2005-07-01) In this study, 16 experiments were conducted to study the effects of pressure on crude oil oxidation in limestone medium. Karakus (29 degrees API), Beykan (32 degrees API), Bati Raman (12 degrees API), Camurlu ( 12 degrees API), Adiyaman (26 degrees API), Garzan (28 degrees API) and Raman (18 degrees API) crude oil from Turkish oil fields were used. The mixture of limestone and the crude oil was subjected to a controlled heating schedule under a constant flow rate of air. The produced gas was analyzed for i...
Influence of coal briquette size on the combustion kinetics Altun, Naci Emre; Bagci, AS (Elsevier BV, 2004-08-15) In this study, the effects of one of the most important parameters in coal briquetting process, the briquette size, on the combustion behaviour of coal briquettes were determined from the view of combustion kinetics, i.e. their liability to ignite and combust. Effect of size on the combustion kinetics was treated by two different approaches. The first one consists of combustion kinetics experiments with briquettes of increasing sizes, thus of expanding volumes. In the second phase, briquette dimensions were...
Effects of operational parameters and ultrasonic pretreatment on supercritical CO2 extraction of diesel fuel from soil Guvenc, A; Mehmetoglu, U; Mehmetoglu, T (Informa UK Limited, 2004-01-01) Supercritical fluid extraction (SFE) using CO2 was performed on soil material artificially contaminated with diesel fuel. Raising the temperature from 313 K to 343 K caused the recovery efficiency to increase from 52 to 76%. Pressure and CO2 flow rate were found to be less important. As expected, increasing extraction time resulted in higher recoveries. Ultrasonic pretreatment of the soil material was found to be very effective, possibly due to disrupting the strong interaction bonding between soil matrix a...
Effect of clay content on combustion reaction parameters Bağcı, Ali Suat (Informa UK Limited, 2005-04-15) The role of clay in reservoirs and its possible influence oil kinetics of crude oil burning is not entirely clear However, it is known that (1) clay fractions of the reservoir matrix possess the highest surface area per gram, (2) clay fractions are the most chemically reactive of the inorganic constituents present in the reservoir and (3) clay minerals generally possess catalytic properties toward various organic liquids. This study was aimed to investigate the role of clay on thermo-oxidative behavior of c...
Effect of crude oil type and heating rate on combustion of crude oil-lignite mixtures Kök, Mustafa Verşan (Elsevier BV, 1992-01-01) Research was conducted to investigate the possibility of upgrading low-quality lignites by mixing them with heavy crude oils. Three crude oil samples with API gravities of 12.9, 18.7 and 26.7 were mixed with lignite to form mixtures of 10 and 20% oil content. Thermal analysis experiments were conducted at non-isothermal heating conditions at heating rates of 5-100 K min-1. Differential thermogravimetric data were analysed using an Arrhenius-type reaction model assuming a first-order reaction. The results in...
