(738f) Synthesis of Anisotropic Calcined Coke from Fast Pyrolysis Bio-Oils
This talk will illustrate a process for production of renewable calcined coke from various fast pyrolysis bio-oils. Biomass is inherently low in undesired impurities. Coke manufacture by coking of biomass oil (as opposed to biomass carbonization) allows production of high-density coke. Finally, coke texture depends on the oxygen content of the coker feed. The desired anisotropic texture is favored by a low oxygen content. A modified pyrolysis process and bio-oil distillation procedure were used. This considerably reduced the oxygen content of the coker feed and yielded coke with the desired texture. Nickel and vanadium concentrations fell below 10 ppm. Sulfur was below 500 ppm. Other metals concentrations can vary, depending on the biomass source.
