The consumption of oil for human needs is increasing in the modern word. With that needs, it is important to use the conversion of the alternative sources of hydrocarbons. One of the promising sources of them is an oil shale. It is possible to convert this substance via pyrolysis or combustion. The possible degree of conversion of this remarkable biopolymer with the nature origin can reach 40%. Recently, thermal analysis techniques have been widely used for investigation of the oil shale oxidative and inert degrad...

Up to date the high content of toxic and corrosive compounds in petroleum gas is one of the main problems. Hydrogen sulfide, a gray carbon monoxide, carbon disulphide, mercaptans; sulfides and disulfides in gas condensates are the most often appeared among the sulfur-containing impurities. This problem can be solved by creation new technological methods for preparation of oil-dissolved gas or development existing ones. Hydrogen sulfide has a high corrosion activity, and the existence of water in the gas increases ...

The presence of metals in aquatic environment is known to cause several health problems to animals and human beings. The levels of heavy metals in wastewater and drinking water must be reduced to the maximum permissible concentration. Clays are abundant and inexpensive layered alumino-silicate minerals that have adsorbent properties. In general, chemical species can interact with clays either by ion exchange or physisorption, both being reversible processes. Among the mineral clays, smectites, especially montmoril...
