Abstract
It is the purpose of this research to convert a batch vacuum pyrolysis process into a pyrolytic process that operates at ambient air pressure with the capabilities of a continuous material flow operation. Further, it is important to optimize the conditions of the pyrolysis process so as to reduce costs of operation and to reasonably maximize products that have value. Steam will be used to displace the combustible atmosphere which enables ambient air pressure operation and elimination of need for inert carrier gasses or evacuation of the apparatus. The use of steam also allows water traps to be used as soft seals that isolate the pyrolysis system from its surroundings and allow a continuous flow of material through the pyrolysis system. This will be accomplished by showing that commercially available parts assembled in a bench scale vacuum pyrolysis apparatus functions similarly to other vacuum pyrolysis systems. Then alterations and modifications to this system will allow operation at ambient air pressure using steam to displace the combustible atmosphere. Once this steam injected pyrolysis apparatus is also shown to operate reasonably similar to an evacuated system, then a steam pyrolysis system and apparatus that can facilitate a continuous flow of material through the apparatus will be constructed and evaluated. The initial pyrolysis apparatus will be comparatively evaluated by their product proportions. Initially, interconnecting consideration will be given to product proportions. Later, pyrolytic apparatus products will give special emphasis to limonene production as the linking product between all variations and changes made in the process and to the various pyrolytic apparatus. In all cases, the liquid product limonene will be used as a comparison point for all systems using steam. Liquid products generated by all pyrolytic apparatus and operational procedures will be prepared and analyzed in a consistent and standard preparation and analysis procedure to ensure reasonable comparison between any of the various pyrolysis apparatus and operational procedures.
