In the course of the research, the effect of competing ions (Na+) on multisorption (Cs+, Sr2+) by composite sorbents based on natural and synthetic zeolites under static conditions was studied. It was found that the maximum concentration of competing ions... see more

The study examines the technology of processing fly ash from Troitskaya power plant for the production of zeolite. The paper presents the results of laboratory studies evaluating the suitability of fly ash from Troitskaya power plant for the production of... see more

The oil shale ash, by-product of the Petrosix process, was used as raw material to synthesize zeolite-type materials. The synthesis procedure was the alkaline fusion followed by refluxing, with three different starting material compositions. Two products ... see more

Due to anthropic activities, the presence of metals in polluted soils has effects on plants development and metals bioaccumulation into trophic levels. In this paper, were followed experiments regarding the tomatoes development into polluted soils with 43... see more

The hierarchical HZSM-5 and Hß zeolites were prepared by alkaline post-treatment methods adopting Na2CO3, TMAOH/NaOH mixture, and NaOH as desilication sources, respectively. More mesopores are produced over two kinds of zeolites, while the micropores port... see more

Hierarchical zeolites containing tin were obtained, characterized and used in a reaction of catalytic isomerization of dihydroxyacetone (DHA) to lactic acid and alkyl lactates. These catalysts are characterized by preserved crystallinity and primary micro... see more

Non-thermal plasma technique can be easily integrated with catalysis and adsorption for environmental applications such as volatile organic compound (VOC) abatement to overcome the shortcomings of individual techniques. This review attempts to give an ove... see more

 Increasing demand on olefins, high energy consumption of thermal cracking and oil depletion are the driving force to find new process to produce olefins. Catalytic cracking of n-butane is promising route to produce olefins. In this paper, we synthes... see more
