using a gas of known composition the beckman analyzer provides measurements of no or no x in ppm tests on a standardized emissions control fuel phillips d2 were performed during each set of emissions tests additionally amoco premier diesel fuel and dodecane which were used as blending bases were also evaluated the following materials were mixed to prepare a fuel 5 g methylol melamine 45 g water 50 g t butyl alcohol 90 g oleic acid log ethanolamine 800 g phillips d2 emissions test diesel fuel and 10 mg mach i superfine alpha fe 2 o 3 catalyst after mixing the fuel was filtered to remove any large catalyst particles emissions performance was then determined in the deutz engine the following results were obtained see table 1 the following materials were mixed to prepare a fuel 5 g urea 45 g water 50 g t butyl alcohol 90 g oleic acid log ethanolamine 800 g phillips d2 emissions test diesel fuel and 10 mg mach i superfine alpha fe 2 o 3 catalyst after mixing the fuel was filtered to remove any large catalyst particles emissions performance was then determined in the deutz engine the following results were obtained see table 2a emissions from the deutz engine burning phillips d2 emissions control fuel were evaluated to provide a base emissions level see table 2a the following materials were mixed to prepare a fuel 20 g astro aricel pc 6n 50 g water 142 g t butyl alcohol 180 g oleic acid 8 g.
