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.

without after processing.
