    Physical Characteristics of Ukpor and Ahoko Clay deposit for use as industrial raw materials
    (Advanced Materials Research: Trans Tech Publications Ltd, Switzerland, 2007-06-15) Eterigho, E. J.; Olutoye, M. A.
    The physical properties of some Nigerian clays were studied in order to determine their suitability for a variety of industrial applications. From the analysis, the specific gravity of Ukpor and Ahoko clays were 1.89 and 2.26 respectively and the Plasticity Index 26.05% and 22.45%, drying shrinkage was 18.90% and 8.2% and particle size distribution showed that the samples are clays. The results show that the physical properties of the clays are within the specifications for kaolin clays and are suitable for industrial uses

    Problems and Challenges of Synthesis of Zeolite and Zeolite-Like Micro-Porous Materials in Nigeria
    (The 1st Nigeria Conference on Zeolite at Ahmadu Bello University, Zaria., 2006) Edoga, M. O.; Eterigho, E. J.; Kovo, A. S.; Ali, M. S.
    In the last few years considerable effort has been made targeted at the synthesis of zeolite and zeolite-like microporous materials with predetermined physicochemical and catalytic properties. However, the position of Nigeria in this global feat cannot be easily defined hence the need for this paper. The problems of zeolite synthesis in Nigeria were highlighted. This is due basically to the non-availability of equipment to conduct detailed analysis of the raw materials and product as well as lack of technical know-how in the area of zeolite synthesis. Also, the absence of common platform for zeolite scientists and technologist for cross fertilization of ideas is another set-back. In this paper, solution was also proffered which if well implemented will launch Nigeria into the amazing world of zeolite and its applications.

    Investigation into the Properties of Clay doped with Silver Ion for Use as a Catalyst
    (Journal of Science and Technology Research (JSTR), 2007) Olutoye, M. A.; Eterigho, E. J.; Agbajelola, O. D.
    The work on the investigation into the properties of clay doped with silver ion for use as a catalyst has been carried out. The clay sample from llorin from llorin, Kwara State, Nigeria was ground, sieved and calcined in a furnace at a temperature of 550- 600'C for a period of 6hrs. The sample was doped with silver ion using 0.2M of NaOH/NaCl Solution with 0.2M AgNO, in a ratio 2:1. The sample was than analyzed using X-ray fluorescence equipment (XRF) [Cement X-ray spectrometer, PW 1660, Philips X-ray Analyser) with a monitor. The following results were obtained 33.44% SiO2, 23.11% 1120g, 9.87% Fe203, 3.86% CaO, 1.98% MgO, 0.01% SO3, 0.87% K,0, 0.71% Na2O, 8.61% L.O.I, 3.03% L.S.F, 1.01S/R and 2.34% A/R for the calcined sample. While that of the doped samples are 33.15% SO2, 22.10 Al203, 9.23%Fe203, 4,44% CaO, 1.99% MgO, 0.04% SO3, 0.96% K2O, 8.10 L. O.1, 3.55 L.S.F, 1.06 S/R and 2.39 A/R. These results when compare with samples having catalytic properties was found to be suitable for use as a catalyst.

    Determination of the Kinetic Parameters in Adhesive Production
    (2008) Olutoye, M. A.; Eterigho, E. J.; Agbajelola, D. O.
    This work is aimed at developing a mathematical model to determine the concentration of Hydrogen Sulphide pollutant in air from the gas flare of a refinery. To achieve this, experimental data on concentration of Hydrogen Sulphide from Kaduna refinery and petrochemical company Nigeria were collected and the dispersion model was developed based on Gaussian distribution principle. The simulation of the model was carried out using visual basic programming. It was observed from the simulated result that the gas dispersion model developed for Hydrogen Sulphide showed a remarkable agreement with the dispersion pattern, and agrees with the experimental results with a correlation co efficient of 0.98. Thus, the model can be used to determine the safe distance for human habitation from an industrial area and the refinery in particular.
