Oxygenates for Advanced Petroleum-Based Diesel Fuels

Abstract:

Oxygenates for diesel fuel are organic compounds such as alcohols ethers and ketones that contain a relatively high concentration of oxygen, The purpose of adding oxygenates to diesel fuel is to reduce the emissions of particulate matter PM in the exhaust, The goal of this project was to select two candidate oxygenate compounds that will be used in a full-scale engine test program to determine which oxygenate will give the greatest improvement in exhaust emissions and performance when blended with conventional diesel. The literature was reviewed for impact of oxygenates on PM emissions to compile oxygenate properties and select test fuel oxygen level. A hypothesis of the mechanism of oxygenate effect on PM formation was developed. Physicochemical properties of oxygenate candidates were collected. Property data was used to screen oxygenates for use in diesel fuel. Oxygenates were ranked according to toxicity and biodegradability. The economics of oxygenate production was estimated. Eight oxygenates were selected for making oxygenate diesel fuel blends for emission testing in a 2.2L diesel engine at a single operating condition Mode 6. The two most promising oxygenates were recommended for making oxygenate diesel fuel blends for future emission testing.
