The feasibility of intensification of vacuum distillation of high-paraffin residual fuel oil from Kumkol crude oil (Kazakhstan) by controlling phase transitions of oil disperse systems through injection of activating additives into the residual fuel oil is investigated. Addition to residual oil of pyrolysis resin and its fractions, which differ in fractional and hydrocarbon composition, produces extreme changes in vacuum gas oil yield, and substantially contributes to shortening of distillation time. Addition of 1 wt. % of wide a pyrolysis resin fraction to residual fuel oil is highly effective. © 2013 Springer Science+Business Media New York.

It is established that in principle opoka from the Kyngrakskoe deposit can be used as raw material for obtaining heat-insulating foam glass by a technology that eliminates the melting process. The optimal sintering temperature, powder dispersity and mass content of sodium hydroxide additive, which make it possible for amorphous foamed material to form from opoka during the heat-treatment process, are determined. © 2013 Springer Science+Business Media New York.

Aluminosilicate rock used for façade ceramic is investigated. It is shown that shale, whose reserves in Southern Kazakhstan are significant, can be used effectively. The use of shale and refractory clay will make it possible to obtain clinker articles with water absorption < 7%. Such raw material has not been used before in the production of façade ceramic. © 2015 Springer Science+Business Media New York
