ABSTRACT Cassava is considered as a potential source for the commercial production of bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological production of bioethanol using microbial amylases. With the progression and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the conversion of complex starch polymer into various valuable met...
This study covers the evaluation of the synergistic effect of Datura stramonium leaves extract-Zn2+ in the corrosion inhibition of mild steel in well water. Varying effects of different concentrations of the extract and 5ppm of Zn2+ on the corrosion inhibition of the mild steel specimen will be determined in order to ascertain the synergistic effect that exists between the leaf extract and Zn2+
ABSTRACT The kinetics and optimization of inhibitive action of leaves extract of pawpaw, Azadirachta indica (neem tree) and bitter leaf on corrosion of mild steel in acidic medium was studied by weight loss technique using central composite design of response surface methodology for optimization. The metal was analyzed using Atomic Absorption Spectrophotometer to determine its elemental compositions. The extract was obtained by liquid extraction using ethanol and was analyzed to determine ...
ABSTRACT Nowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres o...

ABSTRACT The objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cat...
The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...
ABSTRACT The adsorptive removal of the colour pigment (due to high content of carotenoids) from palm oil using ortho-phosphoric acid activated kaolin clay was investigated in this research. The clay was activated at different acid concentrations to improve its adsorptive capacity. In order to study the effect of process variables on the bleaching efficiency of the raw and activated clay ...
ABSTRACT This research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid. It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian v...
ABSTRACT Phytochemicals are chemical compounds produced by plants, generally to help them thrive or thwart competitors, predators, or pathogens. These chemicals are produced by plants through primary or secondary metabolism (Breslin A,2017) . These work was done to determining the presence of phytochemicals such as Tannins, Saponin, Alkaloids, Anthraquinone, Phlobatannins, Flavonoids and Cardiac Glycosides (e.g Steroidal Ring or Terpenoids and cardenolide) from oil extracted from moringa...
Silicon dioxide , also known as silica (from the latin silex), is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and invarious living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials existing as a compound of several minerals and as synthetic product.Notable examples include fused quart, fumed sili...
Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, removing contaminants from the engine, act as a cleaning agent, and act as an anti corrosion and cooling agent. Accordingly, this research effort focuses on comparative study of re-refined engine oils by acid treatment, acid/clay treatment, solven...
Abstract The 15th of October has been decreed a day to focus on germs specifically. It’s the germs on our hand that are in the firing line .The world health organization estimates that 3.5 million children die from diarrhea and lower respiratory tract infections each year. That’s why global hand washing day was decreed. Sanitation of hand has a great effect on the wellbeing of life in general. By maintaining ones sanitation different kind of diseases which are caused by contact can be pre...
Abstract Waste plastic disposal and excessive use of fossil fuels have caused environmentconcerns in the world. Both plastics and petroleum derived fuels are hydrocarbons thatcontain the elements of carbon and hydrogen. The difference between them is that plasticmolecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, itis possible to convert waste plastic into fuels.The main objectives of this study were to understand and optimize the processes of plasticpy...
In preparation and characterization of adsorbent obtained from corn curbs, potassium hydroxide was used as an activating agent at ratio of 1:1, 7:8 and 3:4 with the corn curbs and their pH values were found to be 8.5, 8.03 and 8.0 respectively, ash content were found to be 41.56, 46.78 and 48.31wt%. The BET surface area values were 17.762461, 25.455146 and 201.54631m2/g respectively and the best activated carbon formulation arrived was 3:4 AC. INTRODUCTION An adsorbent is a porou...
