Effect of N₂ and CO₂ on shale oil from pyrolysis of Estonian oil shale

Vaporization Parameters of Primary Pyrolysis Oil from Kukersite Oil Shale

The objective of this study was to obtain vapor pressure and heat of vaporization values of the less volatile heavy end of the Kukersite oil shale primary pyrolysis oil and therefore to have a quantitative insight into the vaporization ability of the oil during the pyrolysis process. The shale oil was produced via rapid pyrolysis in a laboratory scale reactor and collected in a solvent filled c...

Carcinogenicity studies of Estonian oil shale soots.

Several series of chronic experiments in white mice and white rats were carried out in order to determine the carcinogenicity of Estonian oil shale soot as well as the soot from oil shale fuel oil. All the investigated samples of soot showed a relatively low (from 14 to 1200 ppm) benzo(a)pyrene content. The benzene extract of oil shale soot, painted on the skin of white mice, proved to be stron...

Morphological investigations of fibrogenic action of Estonian oil shale dust.

A review of morphological investigations carried out to clarify the pathogenicity of industrial dust produced in the mining and processing of Estonian oil shale is given. Histological examination of lungs of workers in the oil shale industry taken at necropsies showed that the inhalation of oil shale dust over a long period (more than 20 years) may cause the development of occupational pneumoco...

Detailed kinetic analysis of oil shale pyrolysis TGA data

There are significant resources of oil shale in the western United States, which if exploited in an environmentally responsible manner would provide secure access to transportation fuels. Understanding the kinetics of kerogen decomposition to oil is critical to designing a viable process. A dataset of thermo gravimetric analysis (TGA) of the Green River oil shale is provided and two distinct da...
