The hydrogenolysis of glycerol to lower alcohols.Van Ryneveld, Esti. January 2010 (has links)
Much work has been done towards the hydrogenolysis of glycerol to 1,2-PDO and 1,3-PDO
using various heterogeneous systems including Rh, Ru, Pt, PtRu, copper systems and Raney
Ni in batch systems. However, routes to lower alcohols, such as 1-propanol and ethanol have
been less discussed. From an industry point of view, the production of lower alcohols, such as
propanol and ethanol, is very interesting.
Different ruthenium, palladium and platinum catalysts were employed to study the effect of
the support on the catalytic performance in batch mode. These catalysts were evaluated for
their production of lower alcohols, especially 1-propanol using concentrated glycerol
solutions. Among the other solid acids tested in combination with Ru/C, Amberlyst DT gave
the most promising results from a 1-PO point of view, achieving a 34.9 mol% glycerol
conversion with a selectivity of 38 mol% selectivity to 1-propanol. Despite the low glycerol
conversion (1.3 mol%), Pd/C gave a promising 1-PO selectivity (> 85 mol%).
The use of supported Ni catalysts, an inexpensive system, towards the chemical
transformation of glycerol to lower alcohols, has appeared less frequently in the literature.
The activity of Ni supported catalysts on silica and alumina was studied for the
transformation of glycerol to lower alcohols, primarily 1-propanol and ethanol in a fixed bed
continuous flow reactor. Several characterisation techniques were performed on the fresh and
used catalyst, such as BET, XRD, TPD, TPR, TGA and electron microscopy.
The objective was also to continue the development of a more detailed mechanistic
understanding of the formation of lower alcohols from glycerol. In an endeavour to
understand the process better, the role of proposed intermediates, 1,2-propanediol, 1,3-
propanediol, ethylene glycol and ethanol was investigated, as well as the influence of the
hydrogen partial pressure. Under the reaction conditions employed, it was clear that the
hydrogenolysis of C-C and C-O bonds of glycerol took place to a lesser extent when
compared to dehydrogenation and dehydration which are seen as the dominating initial steps.
Ethanol was produced in high selectivities with 1,2-propanediol as feed and 1-propanol was
the main product obtained when 1,3-propanediol was used as feed. / Thesis (Ph.D.)-University of KwaZulu-Natal, Westville, 2010.

Pressure Dependence of Hydrogenolysis of Propane over Supported RutheniumTsjeng, Po 03 1900 (has links)
<p> The hydrogenolysis of propane over 0.5 weight percent ruthenium
supported on (see symbol in text)-alumina in a continuous stirred-tank catalytic reactor was studied at various pressures and temperatures. </p> <p> The reaction orders with respect to propane and hydrogen and the
activation energies were examined at various pressures. A mechanism
was proposed and a Hougen-Watson type of rate expression was obtained
from the analysis of the proposed mechanism. </p> <p> The product distributions were studied at various pressures and temperatures. A reaction network involving reversible adsorption-desorption of the hydrocarbons and irreversible rupture of the carbon-carbon bonds in the surface species was applied to the experimental data. </p> <p> The proposed mechanism was consistent with the data for kinetics and selectivity. </p> / Thesis / Master of Engineering (MEngr)
