Popularity of Nickel in the industrial sector

Nickel is an old element that has been in use for several decades. Initially nickel is used with cobalt to develop different metal components for various applications. After the refining, both elements were combined with different elements to produce alloys. The developed alloys described unlike nature to their parent elements after the amalgamation. It allowed manufacturers to develop several other alloys by using metals in the different magnitudes.
In the old times, rechargeable batteries comprised of nickel and cadmium electrodes that have been overcome by lithium ion batteries as lithium ion offers better performance their precedent. Although nickel was replaced by advanced materials  but nickel alloys have wide significance in the industrial applications.
Nickel alloys are good conductor of electricity and heat while offering good strength due to which the alloys are crucially used in the different industrial applications. Their good conductivity makes them ideal for use in making electronic components. Nickel is also corrosion resistant therefore it is widely used in marine applications.
Nickel alloys have vast applications in the aerospace sector. For their outstanding resistant to heat and corrosion, they have reserved large space in the production of jet engines. The alloys are used in defense and domestic service jet engines.
turbines and exhaust systems. The conducting property of nickel alloys is an advantage to produce complex electric equipments in the aerospace and space craft industries. The automotive industry also uses nickel alloys in manufacturing exhaust equipments, spark plugs and electrical devices. 
The nickel alloys such as monel, nichrome are used in the obtaining fuels, treatment and power production plants. The oil and gas rigs are used in tubing. The heat and corrosion resistive properties make the nickel an ideal material. The petrochemical plants use nickel alloys in the production of vessels, tubing and heat exchanging devices. Moreover the latest industrial applications are the solar engineering and nuclear reactors.
The industrial applications that are high temperature oriented are also using nickel alloys. The heat processing plants use nickel wire in the different areas. The nickel alloys such as nichrome are basically manufactured to perform under the large temperatures. The nickel alloys are utilized in the domestic uses like electrical resistance wire for the electrical cookers. These are introduced in the nickel wire, ribbon, strip for various devices.

The nickel alloys are in the production for several years and the use of these in the abundant of applications has made them the primary alloy in the chemical world.
Study on Nickel mesh catalyst in methane oxidation
The oxidation of natural gas in the presence of catalyst is an essential and common industrial process followed to produce the water gas. In addition of this, the process ensures the confirmed route of intensive studies made on the large and important hydrocarbon production processes. The catalysts used in this process are mostly the transition metals like nickel, copper and iron. Moreover noble elements are also used as catalyst such as Ru, Rh, Pd, Pt and Ir. Among of all these catalyst the nickel based products like nickel mesh offer high performance, high selectivity and cost effectiveness.

However the use of nickel items in the above process causes the production of carbon that hinders the active sites of the catalyst so as the performance of catalyst. This decreases the life of catalyst ultimately. It has been found that the surface produced methyl radicals are more significant in the catalytic oxidation of methane. The methyl radicals tends to stay on the catalytic layer to begin the subsequent reactions or left by the catalyst and they participate in the gasphase reactions. For spongy catalyst, the mass shift constraints for the radicals present inside the holes makes it tough to determine the inter impact of reactions on the catalyst. Therefore the non porous catalysts remove the intraparticle mixing resistance to determine the influences of radical adsorption on process of carbon production and hydrocarbon manufacturing.

In other phase of analysis, the combination of nickel with other metallic elements such as iron used as catalyst to improve the methane transition and increased the catalyst life. The bimetallic catalyst such as nickel-iron alloy enhanced methane conversion and improved life for the production of methane dehydrogenation procedure. Hence it needs finding the influences of enhancements of nickel catalyst by iron for the catalytic oxidation of methane.

In the research the iron plated non porous nickel mesh catalyst through dip coating process for the catalytic oxidation of methane. Specifically the objective of this study is to find the function of nickel mesh blended with ferrous catalyst in the methane oxidation of methane and the product development rates to find the mechanism of product development. The tests were performed in the fixed bed quartz vessel reactor at the high temperature and ambient pressure conditions.

The testing materials nickel mesh catalyst was received from the rare wire weaving. The chemical purity level better than 99.99% methane, highly pure oxygen ultra high purity argon, the whole materials were sourced from Australia are used without after processing.
