PROF CHURCHILL TIENA AKO
Professor Ako attended the University of Ibadan, Nigeria; The Oil and Gas Institute of Bucharest Technical University Rumania (now Oil and Gas University, Ploiesti); the University of Southern California, Los Angeles and University of Lagos, Nigeria where he obtained:
Diplom-Ing (June 1970) in Petroleum Refinery Engineering and Petrochemical Technology; M.Sc (June 1975) Chemical Engineering; M.Sc (June 1976) Petroleum Engineering and PhD (Dec. 1983) Chemical Engineering, respectively.

Prof Ako worked as Process Engineer in Nigeria’s first Oil refinery in Port Harcourt between 1970 and 1974 and later in Nigeria -U.S Petroleum Company (NIGUS petroleum) as its General Manager Marketing and Exploration division between 1986 and 1990.
His teaching and administrative experience in the university started in 1977 as lecturer II. He became a Senior Lecture in 1985, Associate Professor in 1991 and full Chair in 1998 all in the University of Lagos.
At present, Professor Ako is teaching in and coordinating the Petroleum and Chemical Engineering programmes in Covenant University Ota Nigeria.
Professor Ako’s area of specialization is catalysis but is currently engaged in research not only in catalysis but also in petroleum Reservoir Engineering Chemical Engineering, Thermodynamics and Environmental engineering.
A member of several national and international Engineering bodies, professor Ako has supervised over twenty five post graduate students, twenty at masters degree level and three at the doctorate level.
Professor Ako has published over twenty-five articles in both local and international journals. His recent publications are:
Consequently, the rate and the thermodynamic constants were evaluated from the model equations developed using a search technique employing the Nelder and mead modified simplex optimization routine. By using the least squares regression analysis, the activation energies and the heat of adsorption values were evaluated. The result obtained are in excellent agreement with the known and expected trends.

The mechanism and the kinetics of 1-butene isomerization on silica –alumina catalyst was formulated by proposing reaction models and model validation was effected by using literature data collected in an integral reactor at 428K-473K in helium carrier and 1-butene partial pressure of 0.5 atmospheres. A Langmuir- Hishelwood- Hougen-Watson formulation was developed for the triangular reaction network of butene isomerization involving an intermolecular conversion of adsorbed species on the acidic catalyst sites with 2-butyl carbonium secondary ion as a common intermediate. Two models were developed and tested in comparison with the published model of Aguayo et al (1990). Consequently, the rate and the thermodynamic constants were evaluated from the model equations developed using a search technique employing the Nelder and Mead modified simlex optimization routine. The results obtained are in excellent agreement with the known and expected trends Jaiyeola A, and Ako. CT. (2006).

Cryogenic liquid mixtures (cryogens) such as LNG LPG and NGL are extracted from natural gas under very low temperature condition to be used as fuel and as petrochemical feedstock. Rapid phase Transition (RPT) is a phenomenon that is used to describe what happens when accident occurs during marine transportation and loading operation. No real model has yet been presented.
This work applied the Napier-stokes equation with appropriate physical and geometrical assumptions to develop a mathematical model to describe. The simultaneous spreading and evaporation of cryogens spilled on water. The model determined the maximum radial extent of the spill, the duration of the entire process based on the time for complete dissipation of the spill volume, the rate of evaporation with the spill thickness. The result compared favorably with the most recent vigous theoretical model of conrado and vesovic (2000) that was based on mainly thermodynamic consideration.

The Kinetics of n-octane dehydrocyclization reaction has been studied using acidic platinum –alumina catalyst in a micro catalyst reactor in a temperature range of 573-693K with hydrogen as the carries gas at 1.8 atmospheric pressure.
A Lamgmuir–Houngen –Watson type of rate model was developed for the proposed medians involving the aromatization of adsorbed species on the catalyst sites.
