- Abstract
- The hydrocarbon emissions from a combustion bomb were studied in the presence and absence of an oil layer coating the bottom surface of the reactor. Gas samples were analyzed by gas chromatography. Five oils (squalane, a synthetic motor oil, a petroleum-based motor oil, a polypropylene oxide oil and a polypropylene-polyethylene oxide copolymer oil) were studied in combination with three fuels (ethane, propane and butane). Glycerol was studied with propane as the fuel. The fuels were mixed with air at a fuel-lean equivalence ration of 0.9. Under conditions ensuring saturation of the oil layer, the results show that the hydrocarbon emission is principally (>90%) initial fuel and that it varies in direct proportion to the amount of oil present in the reactor, to the initial fuel concentration and to the solubility of the specific fuel in the oil layer. The results also show that the specific compositon of oil layer can have a significant influence on the hydrocarbon emission with a polypropylene-polyethylene oxide copolymer oil producing only 22% of the hydrocarbon emission produced by squalane when .21 gms of the oil are placed in the reactor. Furthermore, when glycerol was tested with propane, no hydrocarbon emission increase was observed.
