Formulation and evaluation of highway transportation fuels from shale and coal oils: project identification and evaluation of optimized alternative fuels. Second annual report, March 20, 1980-March 19, 1981. [Broadcut fuel mixtures of petroleum, shale, and coal products]

PDF Version Also Available for Download.

Description

Project work is reported for the formulation and testing of diesel and broadcut fuels containing components from petroleum, shale oil, and coal liquids. Formulation of most of the fuels was based on refinery modeling studies in the first year of the project. Product blends were prepared with a variety of compositions for use in this project and to distribute to other, similar research programs. Engine testing was conducted in a single-cylinder CLR engine over a range of loads and speeds. Relative performance and emissions were determined in comparison with typical petroleum diesel fuel. With the eight diesel fuels tested, it ... continued below

Description

Project work is reported for the formulation and testing of diesel and broadcut fuels containing components from petroleum, shale oil, and coal liquids. Formulation of most of the fuels was based on refinery modeling studies in the first year of the project. Product blends were prepared with a variety of compositions for use in this project and to distribute to other, similar research programs. Engine testing was conducted in a single-cylinder CLR engine over a range of loads and speeds. Relative performance and emissions were determined in comparison with typical petroleum diesel fuel. With the eight diesel fuels tested, it was found that well refined shale oil products show only minor differences in engine performance and emissions which are related to differences in boiling range. A less refined coal distillate can be used at low concentrations with normal engine performance and increased emissions of particulates and hydrocarbons. Higher concentrations of coal distillate degrade both performance and emissions. Broadcut fuels were tested in the same engine with variable results. All fuels showed increased fuel consumption and hydrocarbon emissions. The increase was greater with higher naphtha content or lower cetane number of the blends. Particulates and nitrogen oxides were high for blends with high 90% distillation temperatures. Operation may have been improved by modifying fuel injection. Cetane and distillation specifications may be advisable for future blends. Additional multi-cylinder and durability testing is planned using diesel fuels and broadcut fuels. Nine gasolines are scheduled for testing in the next phase of the project.
