Abstract
ABSTRACT Synthetic fuels are expected to become a major source of energy supply in the future and major sources of synthetic fuels will be coal, shale oil and tar sand. This paper presents an investigation of hydrotreating using a batch process for bitumen from Nigerian oil sand. The chatacteriistics in conversion of asphaltencs were studied. Various ananlyses were performed to obtain the properties of the bittemen before and after conversion to synthetic crude, e.g., changes of heteroatoms such as sulphur decreases of asphaltics, viscosity add specific gravity, and increases of distillate yield. The process liquid fuel streams that are highly aromatic. The data suggest that the use of hydrogen causes stabilization of reactive intermediates rather than saturation of thermal products.
