Model to Predict the Non-Competitive Inhibition of Petroleum Hydrocarbon DegradationBy Ukpaka. C. P., Ekperi, Nelson. I, Achinike Okogbuke Wonodi, Tom Cyprian, N
Abstract: This investigation involves the development of model to predict the non-competitive inhibition of petroleum hydrocarbon degradation. The result of the model shows the relation between the substrates concentration (hydrocarbon) with time. It was observed that at a very small rate the substrate decrease upon the act of the inhibitor. The non-inhibitor is such that it influences the growth rate of the enzymes substrate formation but attacking not necessarily the active …

Integration of Photo-catalysis of Ultraviolet Rays for Chlorination Process of Methane Conversion into Mono-, Di-, Tri- and Tetra-ChloromethaneBy Ukpaka. C. P.
Abstract: Alkanes the most basic of all organic compounds undergo very few reactions due to its stability. One of the reactions is halogenation, or the substitution of single hydrogen on the alkane for a single halogen to form a haloalkanes. Example of this halogenation of alkanes is the chlorination processes. It is well established that methane-chlorine mixture undergoes substitution reaction at the temp of about 400ºC and presence of light without …

Modelling and Evaluation of Kinetics of Methane Chlorination using Matlab TechniquesBy Ukpaka. C. P.
Abstract: The chlorination of methane follows series-consecutive reaction mechanism to yield the chloromethanes products. The equation of reaction comprised of four consecutive step chemical reaction equations. The kinetics model for chlorination of methane into monochloromethane, dichloromethane, trichloromethane and tetrachloromethane was developed from the chemical reaction equations. In the elementary rate equation, the concentration of chlorine was assumed to be in excess, reducing the model to first order kinetics. The developed model …
