Popovic, Nevena Physical and chemical characterization and upgrading of char derived from scrap tires by ultra fast pyrolysis. Masters thesis, Memorial University of Newfoundland. In the search for a commercially efficient technology for solving the problem of scrap tires, pyrolysis is accepted as an environmentally and economically attractive recycling method to recover useful products from scrap tire waste. The pyrolytic char obtained in this ultra fast pyrolysis process has been characterized and efforts were made to upgrade the product. EnerVision Inc.
Congratulation to Dr. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating". The fragmentation of the biomass molecules generates chemical structures that, upon cooling, result in gaseous products, condensable liquids bio-oil and residual solids bio-carbon. The gas consists mainly of carbon monoxide, hydrogen and methane, with lower amounts of carbon dioxide and ethane. The bio-oil is a dark, viscous mixture of many chemicals, including acids, aldehydes, ketons, furfural, anhydrosugars, phenolics, and water. The bio-carbon consists of the mineral matter of the original biomass entrapped into a porous carbon structure.
The primary focus of this project is to research, develop and evaluate an alternative fast pyrolysis reactor design for the production of bio-oil. The reactor being studied is a radiative free-fall reactor shown in Figure 1. Fast pyrolysis of biomass is the thermal degradation of lignocellulosic material in the absence of oxygen.
