ORGANIC CHEMISTRY Organic Compounds containing Nitrogen

Release of organic nitrogen compounds from kerogen via catalytic hydropyrolysis

High hydrogen pressure pyrolysis (hydropyrolysis) was performed on samples of solvent extracted Kimmeridge Clay Formation source rock with a maturity equivalent to ca. 0.35% vitrinite re ̄ectance. We describe the types and distributions of organic nitrogen compounds in the pyrolysis products (hydropyrolysates) using GCMS. Compounds identi®ed included alkyl-substituted indoles, carbazoles, benzoc...

Utilization of Organic Nitrogen Compounds by Marine and Freshwater Bacteria

Reduced nitrogen species represent the largest pool of nitrogen in many aquatic systems, yet little is known about the chemical composition of this pool and the metabolic pathways required for its remineralization. The long residence time of this material in aquatic systems suggests that it is very refractory and relatively resistant to degradation by direct metabolism or extra-cellular enzymat...

Effect of organic nitrogen compounds on hydrotreater performance

Various distillates are treated with hydrogen gas during hydrotreatment in the presence of catalyst in order to reduce the sulfur and aromatic content of the product. Optimal hydrotreater performance is essential for producing Nynas specialty oils, in order to fulfill the planned production volume and to meet the product specification. Loss of catalyst activity is inevitable during the producti...

Distribution of Nitrogen Ions Generated in the Electrochemical Oxidation of Nitrogen Containing Organic Compounds

The electro-oxidation, over platinized titanium and ruthenium oxide anodes, of nitrogen containing molecules (urea, reactive Blue 4 dye, acetonitrile, formamide, guanidine and pyridazine) was investigated, monitoring the products distribution. The Nmineralization leads to have inorganic pollutants (NH3/NH4 + and/or NO2 /NO3 ). Amidic and aminic compounds react both in homogeneous (acid hydrolys...
