Production of Bioethanol from Cassava Using a Hybrid of Saccharomyces Cerevisiae and Saccharomyces Paradoxus

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 convers...

Synergistic effect of Datura stramonium leaves extract - Zn2+ on the corrosion inhibition of mild steel in well water

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+ 

Kinetic Study and Optimization of Selected Factors Affecting Corrosion Using RSM

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 analyz...

Design and Fabrication of Sedimentation Test Rig

ABSTRACTNowadays, 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 of...

The Principle of Particle Settling in Motionless Fluid

Catalytic conversion of polyethylene to liquid fuel and solid wax using the (CaOH2)

ABSTRACTThe 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 cata...

Air pollution

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 ...

INVESTIGATION INTO THE EFFECTS OF TEMPERATURE ON ITAKPE IRON CONCENTRATE MAGNETO VISCOUS FLUIDS

ABSTRACTThis 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 vis...

Extraction and Phytochemical Analysis of Oil from Neem and Morning Oleifera Seeds and Leaves

ABSTRACTPhytochemicals 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 mo...

Effect of Surface Area on the Extraction of Silica from Rice Husk and Wheat Husk

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 compou...

COMPARATIVE STUDY OF THE DIFFERENT METHODS USED IN RE-REFINING USED LUBRICATING OIL

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, so...

Research Paper on Hand Sanitizer

AbstractThe 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 ...

Conversion of Waste Plastics to Fuel Oil

AbstractWaste 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 plasticpyr...

A Comprehensive Research on Preparation and Characterization of Corn Curbs Adsorbent

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  porous ...
