Effects Of Mixing And Vapor Residence Time On The Thermal Cracking Performance Of Fluidized Beds, Clayton Stanlick
Effects Of Mixing And Vapor Residence Time On The Thermal Cracking Performance Of Fluidized Beds, Clayton Stanlick
Electronic Thesis and Dissertation Repository
The objective of this thesis is to investigate the effects of applied bed mixing and vapor phase residence time on the thermal cracking of agglomerating and non-agglomerating feedstock. Bitumen thermal cracking was investigated using a novel Mechanically Fluidized Reactor system and a pilot-scale Fluid Coking Reactor. Bed mixing and vapor residence time were studied to determine their impacts on agglomerate distributions, yields, and the quality of liquid product. Birchwood pyrolysis was investigated using a fluidized bed reactor to determine the impacts of particle-bed mixing on the pyrolysis of a non-agglomerating feedstock, to provide contrast to the agglomerating bitumen-coke system. It …
Effect Of Liquid-Solid Contact On Thermal Cracking Of Heavy Hydrocarbons In A Mechanically Fluidized Reactor, Mitesh C. Chaudhari
Effect Of Liquid-Solid Contact On Thermal Cracking Of Heavy Hydrocarbons In A Mechanically Fluidized Reactor, Mitesh C. Chaudhari
Electronic Thesis and Dissertation Repository
The aim of the thesis was to study the effect of liquid-solid contact on the thermal cracking of heavy hydrocarbons carried out in Fluid Cokers. The research has been carried out using a Mechanically Fluidized Reactor (MFR) in which the operating conditions of the Fluid CokingTM reactions can be simulated and monitored. The first part of the research, aimed at investigating the effect of agitation on liquid-solid contact, which was carried out by changing the rotation speed of the agitator of the MFR for both non-reactive as well as for reactive systems. In both situations, it was observed that …
