Catalytic processing of coal into liquid fuels: mechanochemical activation of coal Kayrbekov Zhaksyntay 1a, Aubakirov Ermek2b, Myltykbaeva Zhannur3c 1,2,3 Al-Farabi Kazakh National University, Scientific Research Institute of new chemical technologies and materials, Almaty, Kazakhstan aZhaxyntay.Kairbekov@kaznu.kz, b Ermek.Aubakirov@kaznu.kz, cZhannur.Myltykbaeva@kaznu.kz Keywords: Coal, mechanical processing.
Selective transformation of the composition of organic mass of coal (OMC), can contribute to appearance of destructive transformations of carbon materials under milder conditions, thereby changing both the depth and speed of the process and the resulting composition of liquid and gaseous products.
Modern science and technology evolve in the direction of creation of technologies that take place under the influence of high-energies, including the effects of mechanical energy.

Introduction Ammonia decomposition have attracted considerable attention in recent years as a potential method of on-site hydrogen generation for Proton exchange membrane fuel cells (PEMFCs) due to its remarkable advantages compared with the conventional routes from carbonaceous materials[1-4].
In particular, the Mo-based nitrides have attracted considerable attention in recent years, and their performance is affected by the the support materials.

However, there is no comprehensive understanding of the luminescence mechanisms and the development of new materials is very often based on trial and error methods [9].
The starting materials were dissolved in deionised water (Dy2O3 in diluted nitric acid) and stirred on the hotplate until the transparent solution boiled and underwent dehydratation.

Concentrator can use the relatively inexpensive materials such as plastic lenses and metal housings to capture the solar energy shining on a fairly large area and focus that energy onto a smaller area which gives greater power output per unit area of silicon compared to the flat plate systems [2].
Of several choices for a top surface material, a common choice is tempered and low-iron glass.
In many modules, the rear surface material is typically a thin polymer sheet Tedlar.

Raw Materials In order to reduce the cost of heat-resistant concrete, the conventional raw materials were adopted in this paper to make up heat-resistant concrete which is with the highest heat-resistant temperature of 500 ℃.
And the conventional concrete raw materials are normal Portland cement, common crushed aggregates, flyash and polycarboxylate superplasticizer.

The length of the pin is correlated with the thickness of the materials to be joined.
When joining soft materials with hard materials by using friction stir lap welding, it is preferable, as the first step, to plunge the pin through the softer material to avoid damage to the pin.
