The hydroliquefaction of Göynük oil shale with/without catalyst was carried out in the presence of supercritical toluene. The maximum conversion and the yield of extract was reached at 400°C for non-catalysis hydroliquefaction experiments. The conversion and the yield of extract reached a maximum value at 400°C for catalytic hydroliquefaction with pyrite. The pyrite catalyst showed no noticable effect...
Temperature programmed co-pyrolysis of Turkish oil shales with LDPE was investigated. The aim of this research was to determine the volatile product distribution and product evolution rate of coprocessing of oil shale with LDPE. A series co-pyrolysis operation was performed with oil shale and LDPE using a 1:3, 1:1, 3:1 total carbon ratio of oil shale to plastic. A fixed bed reactor was used to pyrolyse...
A fixed-bed reactor was used to pyrolyse small samples of oil shale particles under an inert gas flow (argon). A special sampling technique was used for collecting organic products eluted from the reactor at different temperatures and time intervals. The pyrolysis products were analysed by capillary gas chromatography and the total product evolution rate was investigated as a function of temperature...
Temperature-programmed pyrolysis of Beypazari (Turkey) and Timahdit (Morocco) oil shales was investigated. The maximum product evolution temperatures were determined for each sample. n-Paraffins and 1-olefins in the pyrolysis products were classified by carbon number. The effect of kerogen types on the distribution of n-paraffins and 1-olefins was also investigated.
In this study, the kerogen types of Goynuk, Beypazari oil shale from Turkey and Timahdit oil shale from Morocco were defined by infrared spectroscopy. Aliphatic, carboxyl/carbonyl and aromatic compounds were considered in order to classify the kerogen types. The IR-analysis result shows that the samples can be classified in kerogen evaluation path I for Goynuk, Timahdit oil shales and path II for...
Goynuk oil shale was subjected to slow pyrolysis and flash pyrolysis. It was also subjected to super and subcritical fluid extraction with water. Considerable differences were observed in the yields and compositions of the oils obtained under the four different conditions.
