Abstract
Although the demand for petroleum products is expected to decrease, diesel fuel is relatively stable. To increase the production of diesel fuel, the ways of blending kerosene and expanding to utilize cracked diesel fuel are used. Since the cracked diesel fuel has high aromatic and naphthenic components, which increase the amount of PM. So, it is necessary to take countermeasures such as lightning of distillation. To identify the impacts of these properties on PM production, the test was conducted using test fuels varying compositions and distillation properties.
