Catalytic Pyrolysis Of Poly Vinyl Chloride As A Viable Way Of Waste Management, Randy Santos, Foster A. Agblevor Aug 2016

Catalytic Pyrolysis Of Poly Vinyl Chloride As A Viable Way Of Waste Management, Randy Santos, Foster A. Agblevor

All Graduate Plan B and other Reports

The main purpose of this investigation is to achieve the dechlorination and cracking of PVC producing a low chlorinated oil using a single step process; finding and using a suitable adsorbent that captures the chlorine released in the decomposition of the Poly Vinyl Chloride in the solid phase; then use the adsorbent to enhance red mud chlorine absorption activity. Find an alternative viable use for the waste PVC and red mud that will reduce landfilling. Calcium Hydroxide was selected as the main chlorine adsorbent since it captured 75% chlorine in the solid phase. The calcium hydroxide was mixed with red ...


Gasification Of Liquid Sprays In An Entrained Flow Gasifier, Nicholas Ryan Creager Jan 2016

Gasification Of Liquid Sprays In An Entrained Flow Gasifier, Nicholas Ryan Creager

Graduate Theses and Dissertations

In an advancing technological world, gasification is a relatively mature technology that can be refreshed to help achieve sustainable energy production. This thesis discusses the development of a pressurized gasification system that converts bio-oil from fast pyrolysis of red oak into producer gas. Focus will be given to the challenges of operating a pressurized system at high temperature while injecting a non-uniform liquid. Demonstration experiments using methanol resulted in development of experimental methods to show critical nozzle designs and their affects on gasification of liquid jets.

Start up of the bio-oil gasification system was performed using methanol as a model ...


Experimental Investigation Of Fast Pyrolysis Of Arundo Donax In A Novel Paddle Reactor, Chintan Desai Jan 2016

Experimental Investigation Of Fast Pyrolysis Of Arundo Donax In A Novel Paddle Reactor, Chintan Desai

Dissertations, Master's Theses and Master's Reports

The main objective of this research was to show the effectiveness of a novel paddle reactor for fast pyrolysis and study the effect of biomass particle size and reaction temperature of Arundo Donax a type of energy crop on the bio-oil yields. The novel paddle reactor showed effective mixing and heat transfer which were proved with the help of studying the residence time and the heating characteristics of the system respectively. The effect of different biomass particle sizes on the bio-oil yield was not significant, the bio-oil yield was approximately 50% for all the sizes. For Arundo Donax particle sizes ...
