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 and contamination.

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...
Effect of heating rate on thermal properties and kinetics of raw and cleaned coal samples Özbas, Kazim Esber; Hicyilmaz, Cahit; Kök, Mustafa Verşan (Informa UK Limited, 2003-01-01) 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 m...
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...
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...
PREDICTION OF BED MATERIAL ACTIVITY FROM CHANGES IN CARBON-DIOXIDE CONCENTRATION FOLLOWING COAL PARTICLE INJECTION IN THE FLUIDIZED-BED REACTOR VURAL, H (Elsevier BV, 1994-01-01) An electrically heated laboratory scale fluidized bed reactor was used for measurement of carbon dioxide concentrations from the devolatilization of bituminous coal under conditions pertinent to a large scale atmospheric pressure fluidized bed combustor (AFBC). Feeding a few particles into the bed, which contained 1 or 2 g of char, produced an increase in CO2 concentration. The quantity of CO2 released from the fluidized bed was found to be a function of fluidizing solid material, as well as the bed tempera...
