Abstract
A method of upgrading naphtha and diesel yields from fluid catalytic cracking and hydrocracking units by improving a feed quality of a petroleum feedstock, product or fraction mixture. The method of improving the feed quality of the petroleum feedstock, product or fraction mixture occurs by first determining the API Gravity of a petroleum feedstock, product or fraction mixture. A temperature at which about fifty percent of the petroleum feedstock, product or fraction boils (T50) is then determined. The feed quality for the petroleum feedstock, product or fraction mixture as determined from the API Gravity and the T50 for the feedstock, product or fraction mixture is then estimated followed by adjusting the petroleum feedstock, product or fraction mixture to achieve a higher feed quality.
