Could some expert explain how to calculate the overlap between gasoline and diesel?
The degree of overlap between gasoline and diesel refers to the extent of similarity between them in terms of carbon count, molecular weight, etc. Generally speaking, the higher the degree of overlap, the more similar the properties of the two fuels are, such as cetane number and freezing point. The degree of overlap between gasoline and diesel can be calculated using the following formula: Degree of overlap = 100% - |Average carbon number difference|/Average carbon number × 100%. Here, the average carbon number difference is the average of the sums of the absolute values of the differences in carbon numbers among the various components in gasoline and diesel, divided by the number of components; while the average carbon number is the average of the products of the carbon numbers of each component in gasoline and diesel and the number of components. It should be noted that this formula is only applicable to comparisons between gasoline and diesel with the same number of buckets. Furthermore, there are many other factors in practice that also affect the properties of the two fuels; therefore, the degree of overlap is merely a reference value for measuring the similarity between the two fuels. .
Do you mean the degree of overlap during fractionation or for the product?
