Project summary

The synthesis of high-silica zeolites, their radiation and chemical modification and the study of catalytic activity for methanol conversion into hydrocarbons and ethers is envisaged under the present project. These activities are of great importance both for the practical purposes and in view of revealing a mechanism of methanol conversion on zeolites.

The main objectives of the project are as follow:


- to develop a new approach to high-silica zeolites synthesis based on zol-gel method;
- to study the catalytic activity of the synthesized zeolites for the methanol conversion into hydrocarbons and ethers;
- to identify new zeolite phases;
- to study an influence of zol-gel method on the reaction rate, the temperature and the phase composition of zeolites synthesized by hydrothermal method;
- to find out the conditions for high-silica zeolites synthesis in non-aqueous medium;
- to study in details the radiation and chemical modification of the synthesized high-silica zeolites aimed at improving their catalytic properties;
- to study an influence of the radiation and chemical modification on the sorption and catalytic activity of zeolites;
- to synthesize H-and metal-containing zeolites directly without an ion exchange process;
- to compare the catalytic activity of zeolites synthesized by using the abovementioned methods with that for zeolites produced by the conventional methods;

The following practical problems will be solved as the result of the project implementation:

- revealing the optimal conditions for the direct synthesis of the zeolite catalysts;

- applicability of the sol-gel method and its influence on the conditions of the zeolite synthesis;

- radiation induced improving of catalytic activity of the catalysts synthesized by the methods proposed; recommendation of new types of catalysts and new reactions based on the zeolite catalysts;

- development and proposal of new method for the catalytic methanol conversion into 1,2,4,5-tetramethylbenzene – durene the raw material for the polyamide films production;

- development the environmentally sound technologies.

This proposal corresponds to status and goals of ISTC and will give an opportunity to the Armenian scientists from SEUA and YerPhy who participated earlier in the military programs to be involves in solving the peaceful scientific problems and join to the international community of the scientists.

The efficiency of the radiation influence on catalytic activity of zeolites will be justified as the result of the project implementation.
