Abstract:

Converting heavy ends of petroleum，which has a high C/H value，to carbon materials by dehydrogenation is an important approach to making efficient use of such heary ends，because petroleum is becoming heavier and more than 10% of crude oil is super heavy components that cannot be converted into light oil by the present technology. In this review，recent developments in the synthesis of carbon functional materials from heavy ends of petroleum are introduced，including the synthesis approaches by direct dehydrogenation of heavy oil and a self-assembly process in gas or liquid phase. The carbon functional materials prepared from heavy ends of petroleum include active carbon，carbon foam，carbon fibers，carbon nano-materials and versatile composites or doped carbon materials. Strongpoints and shortcomings of the preparation of carbon functional materials from heavy ends of petroleum are presented，and suggestions for future research are made.
