Abstract (sommario):

<p>In recent years the levels of sulfur and benzene in the gasoline pool have been reduced, and in the future there may also be new regulations on vapor pressure and the level of aromatics and olefins as well. The limitations on vapor pressure and aromatics will lead to reduced use of C<sub>4</sub> and reformate respectively. The branched isomers of C<sub>5</sub> and C<sub>6</sub> alkanes have high octane numbers compared to the straight chain isomers, and are consequently valuable additives to the gasoline pool. To maintain the octane rating, it is predicted that an increased share of isomera

Abstract (sommario):

The basics of the oxidation mechanism of different alkanes within zeolites and over molybdenum oxide surfaces were studied employing state of the art computational modelling. It was shown that the constrained environment inside MFI, MFS and MOR induces terminal selectivity on the reaction of 6-, 8- and 10- term linear alkanes, i.e. hexane, octane and decane, respectively. The Monte Carlo (MC) random alkane configuration sampling showed that the oxidation reactivity is driven by the fact that the terminal C atoms of the substrate are more likely to be closer to the zeolites internal walls than

Abstract (sommario):

Unspecific peroxygenase (EC 1.11.2.1) represents a group of secreted hemethiolate proteins that are capable of catalyzing the selective mono-oxygenation of diverse organic compounds using only H2O2 as a cosubstrate. In this study, the peroxygenase from Agrocybe aegerita (AaeUPO) was found to catalyze the hydroxylation of various linear (e.g n-hexane), branched (e.g. 2,3-dimethylbutane) and cyclic alkanes (e.g. cyclohexane). The size of n-alkane substrates converted by AaeUPO ranged from gaseous propane (C3) to n-hexadecane (C16). They were mono-hydroxylated mainly at the C2 and C3 position, ra

The importance of alkanes hydroisomerization arises from the continuingly stricter regulations imposed on the utilization of gasoline as an automotive fuel.

The aim of this project is to investigate the terminal activation of long chain linear alkanes in the liquid phase using the selective oxidation of w-decane to 1-decanol as a model reaction. Firstly the autoxidation of -decane with oxygen was studied. The product distribution is a mixture of Cio ketones and alcohols with shorter chain carboxylic acids. The radical autoxidation mechanism promotes oxidation in the internal position and a very low terminal selectivity is found in the product profile. A range of VMgO catalysts were tested for the oxidation of w-decane with oxygen. Leached vanadium

Hydrocarbon chains are a basic component in a number of systems as diverse as biological membranes, phospholipids and polymers.

This technique, sensitive to molecular details, is the only one able to both identify and quantify conformational disorder present in paraffinic systems. To achieve this, methyl deformations have been widely used as "internal standards" for the normalisation of peak
