Structural Study and Upgrading of Kazakhstan Oil Sands

In the paper separation methods of organic part from oil sands were investigated at experimentally. For the determination of organic part (liquid fraction) of oil sands the extraction methods was used in Soxhlet apparatus by solvent. Thermal processing was carried out with a monotonic heating of oil sands from room temperature to 500 ºC. As showing results, organic part of Beke and Munayli-Mola oil sands studied by extraction method were 12.0 wt.% and 16 wt.%. Thermal processing results showed, that the organic part of Beke and Munayli-Mola oil sands were 9.6 wt.% and 13.5 wt.%. Physical and chemical characteristics of liquid fraction are established by standard methods.

Extraction and Thermal Processing of Beke Oil Sands

In the paper separation methods of organic part from oil sands were investigated at experimantally. For the determination of organic part (liquid fraction) of oil sands the extraction methods was used in Soxhlet apparatus by solvent. Thermal processing was carried out with a monotonic heating of oil sands from room temperature to 560 0C. As showing results, organic part of Beke oil sands studied by extraction method were 12.0 wt.%. Thermal processing results showed, that the organic part of Beke oil sands were 9.6 wt.%. Physical and mechanical characteristics of liquid fraction are established by standard methods.

Effect of Composite Shape-Stabilized Phase Change Material on Asphalt Mixture Temperature

It provides a new way to solve the worldwide the low-temperature cracking and high temperature rutting distresses of the asphalt pavement, by mixing the composite shape-stabilized phase change material (CSPCM) to asphalt mixture. The effect of CSPCM on the temperature of asphalt mixture is analyzed by the monotonic cooling test, the monotonic heating test and the outdoor simulating cycle test. The results of monotonic cooling and heating tests indicate that mixing CSPCM into asphalt mixture can increase the temperature of asphalt mixture during cooling process and decrease the temperature of asphalt mixture during heating process. It has a temperature damping effect as well. The results of outdoor simulation test shows that mixing CSPCM into asphalt mixture decreases the maximum temperature of the bottom of the specimen and increases the minimum temperature of the bottom of the specimen. It cannot change the critical temperature occurring time of the bottom of the specimen. The test results indicate that mixing CSPCM into asphalt mixture could actively adjust the working temperature of asphalt mixture, prolong the ideal temperature of asphalt mixture and improve asphalt mixture’s adaptability to the changing environment.
