ABSTRACT
This study
has its theme as a utilization studies of Enugu
coals with the view of studying its properties, classification, preparation
storage etc comparing coals obtained from different locations.
The Enugu coal is a sub-bitummous and non coking
coal. It is very rich in waxes and
resins, thus it may be suitable for the production of liquid fuels and a range
of chemical raw materials.
After all necessary studies which
includes proximate analysis, ultimate analysis, caebonization tests,
classification test, chemical and petrographic propertics, coal blending
studies, from coking studies etc a wide range of chemical products was found
present in the Enugu
coal. It is obvious that for waxy and
resinous materials of which Enugu
coal is there are rumbrous applications in the chemical industry.
The development and acquisition of
coal utilization technology was this frustrated due to coal fields were
underdeveloped and this inadvently contributed to near abandonment of the
existing coal field. In solving the
problem associated with this, the country must therefore follow the foot-steps
of the industrialized nations by encouraging research and also voting in large sums of money on developments of coal
associated with the extraction, processing and use of coal.

INTRODUCTION
Coal is a
black combustible compact, & stratified inhomogeneous mass of arganic
material originated from metamorphosed plant which is usually found
interspersed with smaller amount of inorganic mather in its sedimentary
rocks. Coal formation has occurred over
long period of time, often under high pressure of overburden at elevated
temperature and also with the actions of some bacteria.
Coal still provide a large portion of
the words energy reguirements, accounting for 40% of worldwide electricity
generation and for process weat in many industries. As the planets population and energy use
expand in the future, the use of coal is bound to increase in the future
because words reseros are large and widespread and coal is a low-cost
alternative to other fuels.
Coal has a significant role to play in
the industrial development of Nigeria. Apart from crucial role of coal in the
metallurgical industry. It is also a
major substitute for petroleum by products in the chemical industry. The enormous potential of coal resources in
the overall economic development of Nigeria has prompted the need to
consider how best to update information and knowledge of the coal utilization
of this country.
As rate as 1949, the British colonial
government commissioned a study the report of which clearly showed the chemical
utilization of the Nigeria (Enugu) coal in the following words; “the production
of all liquid fuel requirements of Nigeria and adjacent territories, and the
development of an export chemical industry is of such technical and economic
promise as to justify the active prosecution of the chemical utilization
project.
The project focuses on the utilization
studies of the Eungu coal and also on the re-integeration of coal the energy
mix of Nigeria
with a new to pringing out its potentials establish chamels of exchange of
information and laso build up a bank of documented results. The most auspicious of this point of view of
its export ability, but also for its local consumption or needs for power
generation and metallurgical coke production.
In Nigeria
coal is found in commercial quantity in Enugu
and hence Enugu is euphemically repred toas the
coal city†Enugu
coal met the need of our rellacy system and electricity supply in addition to
employment opportunities for Nigerians.
Futher more, many chemicals of higher commercial values can be derived
from coal which ran lead to building coal-based chemical plant in enugu state
or other neighbouring state of the country.
In this project some factors reelected
to the utilization of Enugu coal were looked into like Historical background of
Enugu coal, coal fields, geological assessment, coal properties,
classification, preparation, thermal decomposition and gasification of coal,
some experiements and their results help in the importance and utilization of
this Enugu coal.
It view of Nigeria over dependence on
crude oil and the oil glot undermined further developments, exploitation and
diversigation of our coal industry. To reverse the trend the extraction of our
coal mus be improved.
Nigerian
cement company, Nkalagu was designed to utilized Enugu coal for energe in their clinker
production. So also the Oji River
power station was designed to utilize Enugu
coal for electricity generation. With
oil boom coupled with the war coal suggered a major setback in the both
production and utilization and the development of technologies for more
efficient coal utilization. Conversion
to heat from gaseous and liquid fuels should be one of the prime objectives in
meeting the energy requirements of this country.
It will be tantamount to economics
short sightedness if the importance of coal in the industrial development of
this country is judged by its present low level of its utilization. The Enugu
coal industry must be seen as a long neglected economic frontiers that needs
urgent resuscitation.
Therefore, proper management of
available coal resources is essential for maximum coal utilization, which to a
large extent, determines the level of detail exploration.
