Influence of wood humidity of three species (Prosopis africana, Anogeissus leiocarpa and Tectona grandis) on the production of charcoal by the traditional wheel

  Charcoal production is an increasing practice which however, remains traditional in Benin despite the introduction of new techniques of carbonization. The objective of this study is to evaluate the effect of species humidity on the production process, in the perspective of improving the yield in relation to farming practices. To achieve this, three wood species appearing in four humidity conditions were used...

Epoxidation of Ximenia americana seed oil

  Epoxidized Ximenia americana seed oil may be well suited in the partial replacement of petroleum products in synthesis of polyol. However, a process is needed to obtain this material from X. americana seed oil at sufficient conversion and scale to assess products. Therefore, X. americana seed oil was extracted using hot-water process and finally epoxidized in a solvent-free...

Application of re-refined used lubricating oil as base oil for the formulation of oil based drilling mud - A comparative study

  The viability of using re-refined used lubricating oil (RULO) extracted with an aromatic selective normal methylpyrolidone (NMP) as base oil for the formulation of drilling mud was investigated. The rheological and other properties of this formulation were compared with formulations from three locally produced synthetic base oils. The synthetic base oils were Paradril® made from saturated linear ethylene...
