Abstract
A 5ci Am-Be source based experimental set up for the determination of H content and (0+C) atomic ratio in oil or Hhydrocarbon samples and coal or solid mineral samples has been developed at the Centre for Energy Research and Training (CERT). It utilizes the thermal neutron reflection technique in which the relative intensity of thermal neutrons reflected by a bulk sample is used to etermine its total hydrogen content. Use is made of chemicals of known chemical formula
and carbon black of known carbon content to obtain the calibration line which establishes the relation between the hydrogen content, (0+C) atomic ratio and the reflected H thermal neutrons. The fabricated set up was used to analyze edible and non-edible oil samples. The samples quality was relatively graded in terms of the hydrogen content and (0+C) atomic H
ratio. The detection limit of 0.25 H w% was obtained for
hydrogen. The adaptation of this technique for quality control of petroleum products was established by the analysis of used
and un-used lubricants. The facility is economical and recommended for use in the determination of moisture content
of solid minerals and building materials.
