NITROGEN COMPOUND DISTRIBUTION IN A HEATING OIL

摘要

A Number 1 fuel heating oil was studied for the organo-nitrogen content. The organo-nitrogen compounds were isolated by mild acid extraction followed by silical gel adsorption. Three extracts were studied - a basic nitrogen extract in methylene chloride, a nonbasic nitrogen extract in methyl alcohol and a nonbasic nitrogen extract in methylene chloride. The major constituents of each extract were identified by GC/MS. There were seven major classes of nitrogen compounds detected in each extract. There compounds included alkyl-substituted carbazoles, indoles, pyrazines, pyridines, pyrroles, quinolines and tetrahydroquinolines. The nitrogen content and distribution was compared to both tar-sands and shale derived fuels.
