Introduction Dimethyl ether (DME) is an important chemical raw material for many chemical compounds, such as dimethyl sulfate, methyl acetate and light olefins.
The study of carbonaceous residues on the surface of ZSM-5 zeolite in the synthesis of DME is an urgent task, and its solution is the key for choosing the optimal dehydration catalyst.
Materials and methods It is well known that zeolite catalysts have one disadvantage connected with low resistance to coking, i.e. even small amounts of carbon greatly reduces the catalytic activity of zeolites.
The method of temperature-programmed oxidation (TPO) was used to study the possibility of coke oxidation on the material surface in the temperature range of 25-900 °C.

There are many coal-fired power plants, construction material production factories (such as cement, ceramic, fire clay, and brick factories), chemical and metallurgic industry in this area.
A set of standard materials were used for quantitative analysis, such as Al2O3 (99.9%), SiO2 (99.9%), CaCO3 (99.9%), ZnCl2 (99.9%), MgO (99.9%), MnO2 (99.0%), KCl (99.9%), Fe2O3 (accounted in the form of Fe，69.8% ~70.1%), TiO2 (99.9%), Pb(CH3COO)2·3H2O (99.9%), CuSO4·5H2O (99.9%), and Na3PO4·12H2O (99.0%).
It may come from transport of ground dust, or from industrial smoke dust, but from the view that mineral composition of each industrial raw material (e.g. raw coal), the content of quartz is very small in normal conditions.

Among the various types of power devices, SiC-based metal-oxide-semiconductor field-effect transistors (MOSFETs), which provide a normally-off characteristic, should become a key component for next generation green electronics.
Taking into account the trade-off relationship between energy bandgap and permittivity of dielectric materials, Al-based oxides seem to be suitable for SiC-MOS devices due to its wide bandgap and excellent thermal stability.

Therefore, the external force is applied to steel wire ropes shall be a dynamic response, adjustable data, this is the key technology of sliding ropes brake.
Selection of sliding ropes brake structure, must considers how to through the mechanical external force applies to the sliding steel wire ropes, the material contacted to steel wire ropes is a certain wear resistance and friction coefficient, also can not has high hardness, namely during the process of steel wire ropes dynamic braked, the material contacted to steel wire ropes wears smaller is better, friction coefficient the bigger the better, the mechanical damage to steel wire ropes as small as possible.
Therefore, the sliding ropes brake selects a double action hydraulic cylinder structure, the material of brake pad is the homogeneous material as the friction pad, the assembly of brake pad is on the head of double action hydraulic cylinder, direct contacts the steel wire ropes.

MATERIALS AND METHODS Pondicherry is the capital city of Puducherry state situated in the coromandal coast of Bay of Bengal and ruled by the French before 16th August 1947.

Introduction Currently, nickel oxide NiO has shown itself to be a promising material.
On the ground of this material were realized such applications as power diode structures [3], HEMT transistors [5], UV photodiodes [6], and solar cells [7].
At the same time, this material itself can be in demand in various sensors, such as semiconductor gas detectors [8,9].
This is largely due to the presence in the film, in addition to the Ni2+ state characteristic of stoichiometric material, the inclusion of the Ni3+ state [10].
