| 摘要 |
The present invention provides a method to determine the chemical concentration of one or more of a number of the constituent classes of a hydrocarbon feed to or product from a hydrocarbon treating process (such as a catalytic cracking process). These constituent classes, which are referred to as "lumps", include up to 14 different molecular types in up to 4 different boiling range fractions. A specific lump will include all individual molecular components which are expected to react in a similar way in the catalytic cracking unit. <IMAGE> |
