Hydrodeoxygenation Of Anisole In A Novel Externally Agitated Reactor, Brett Pomeroy
Hydrodeoxygenation Of Anisole In A Novel Externally Agitated Reactor, Brett Pomeroy
Electronic Thesis and Dissertation Repository
Bio-oil upgrading via hydrodeoxygenation (HDO) was investigated using anisole, a model compound, in a novel Externally Agitated (EA) reactor which is expected to enhance gas-liquid-solid mixing. Operating conditions were established based on anisole HDO with 10 wt.% Ni on silica, γ-alumina, and δ-alumina while varying temperatures between 160 to 280oC, and reaction times between 30 – 90 minutes. Mild temperatures of 220oC and 45 minutes for reaction time with γ-alumina were selected for subsequent work since γ-alumina demonstrated the highest HDO activity. HDO was then investigated with varying Ni-Cu and Ni loadings. Despite the improved reducibility …
Application Of Mechanically Fluidized Reactors To Lignin Pyrolysis, Valentina Lago
Application Of Mechanically Fluidized Reactors To Lignin Pyrolysis, Valentina Lago
Electronic Thesis and Dissertation Repository
Lignin has great potential for the production of aromatics currently derived from petroleum, since it is the most abundant source of aromatics in nature. At present, Kraft lignin is used as fuel within the pulping process but, alternatively, it could be converted to high-value chemicals using thermochemical processes such as pyrolysis. Kraft lignin, however, is a very cohesive and thermally sensitive powder with foaming and agglomerating tendency under reaction conditions. Therefore, new reactor designs are necessary to efficiently process this raw material.
Consequently, a novel reactor design, designated as Mechanically Fluidized Reactor (MFR) has been developed to successfully process Kraft …
