Several heterogeneously catalysed reactions have been studied at pressures above and below the critical pressure of carbon dioxide in both carbon dioxide and nitrogen. The purpose of this study was to ascertain if carbon dioxide above its critical pressure and temperature would …

Petrochemical and fine chemical industries face a daunting problem in recovering acetic acid from its aqueous solutions. The recovery of acetic acid could be done through esterification reaction. However, esterification is an equilibrium limited reaction. Multi-functional reacto…

Biomass, being the only renewable source of carbon, has the potential to serve as a sustainable platform for the production of energy and chemicals, in this era of diminishing supplies of fossil fuels. The conversion of lignocellulose to fuels and chemicals requires the effectiv…

Catalytic events are ubiquitous throughout the study of chemical processes. A catalyst is responsible for lowering activation energies for reactions that otherwise would be unfavorable under typical reaction settings. While there has been substantial progress in the field, a com…

This study focuses on the development of novel two-stage esterification-transesterification synthesis of biodiesel from used cooking oil (UCO) using novel heterogeneous catalysts. The esterification of the UCO was investigated using three types of ion exchange resins catalysts i…
