Project summary

The aim of the Project: design of the scientific basement and experimental validation of methods for disposal of toxic elemental organic wastes in the process of thermal oxidizing destruction. The distinctive feature of these processes is the formation of new solid phase in the reactor at high temperature. Solid particles can cause the destruction of the reactor, deposit on the reactor walls, change the conditions of heat conductance and cause the set of different technological complications. This is the reason why the modern technologies for processing of such wastes are practically absent.

One of example of such wastes is aluminum-organic and silicon organic compounds and their mixtures. The first one are the wastes of widely spread all over the world production of high pressure polyethylene based on the catalyst of Zigler-Natta. In this case the solid particles are the thin powder of aluminum oxides. It is known that corundum is the thermodynamic stable phase of aluminum oxide at high temperatures. The corundum has high abrasive properties.

The being in exploitation hydraulic liquids and oils based on alkylsiloxanes are the examples of silicon organic compounds. The silicon oxides also have high erosion ability.

The scientific aim of this Project is study of kinetics of formation of new solid particles and possibilities to control the phase composition of powders.

The basement to start this work is theoretical analysis, which was fulfilled on the base of experimental results obtained for the processes of powders formation in different conditions. It was shown that the crystalline (equilibrium) structure did not have enough time for formation at small reaction time and time of product quenching. The solid products of processes at such conditions are amorphous particles (non-equilibrium structures). It is well known that the hardness of amorphous particles several order of magnitude less than that of crystalline particles with the same composition. Correspondingly the erosion activity of such powders is also much less than that for powders produced in other conditions.

The reactor, which is necessary to produce non-equilibrium structures, should provide the disposal of wastes at high temperatures for short period. This is necessary condition for formation of non-equilibrium structures. Known technological methods for wastes processing can not simultaneously provide the deep disposal of wastes and formation of non-equilibrium structures.

Realization of such conditions is possible in high temperature reactors based on modified liquid propellant rocket engines (LPRE). Authors of this Project have large experience in design and testing of such reactors. The problems of high efficiency destruction of toxic wastes of other classes (phosphorous and chlorine continued) were successfully solved. This work was held in cooperation with TNO (the Netherlands).

High-qualified specialists in the field of study and design of chemical processes in the presence of solids take part in the authors collective. The main staff of authors of this Project includes experts in the rocket technologies (design of fuels, design and manufacturing of rocket engines, testing of engines). The use of their experience and scientific potential for solution of problems, which are not directed to design and modernization of methods of transportation is one of the main aims of the Project. The Project will also facilitate the integration of scientists from CIS in international scientific community, will support fundamental and applied study and design of peaceful technologies especially in the field of safe of surroundings and energy production.

Large number of theoretical and experimental studies will be fulfilled during the Project:

– study of internal chamber processes during the burning accompanied by solids formation in the chemical reactors based on rocket technologies;

– study of correlation of combustion conditions and formation of new solid phase;
– experimental study of influences of disposal conditions on phase composition of formed powders by means of X-ray diffraction;
– experimental study of distribution function of particles on their dimensions and its dependence from process conditions;
– thermodynamic calculations and creation of base of data on processes including the formation of solids;
– study of erosion ability of dust high temperature fluxes for different materials.

Institute for Applied Researches (TNO, Prins Mauritz Laboratory, The Netherlands) is the Collaborator for the Project. This organization took part in our joint work related with wastes disposal. The cooperation with the Collaborator in the frame of this Project will be realized in different directions:

– exchange in information during the Project realization;

– preparing Comments to the technical reports;
– share of having experience on the Project topics;
– organizing the joint symposiums and workshops.

The importance of the Project for purposes of ISTC:

– to give possibility for scientists and specialists which are related with weapons to re-orient their abilities to peaceful activity;

– help to integrate scientists into the international science community;
– support fundamental and applied study and design of technologies in peaceful purposes, especially in the field of safe of surroundings;
– assistance in the solution of national and international technical problems;
– support the transition to the market economy, which is correspond to the civic needs.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
