ANALYTICAL METHOD TO DETERMINE THE GUM CONTENT IN A HYDROCARBON

摘要

A method of determining gum content and performing quality control in the production of a gasoline to minimize the gum content in the produced gasoline. A representative sample of the gasoline is subjected to UV spectrophotometric analysis and the peak heights representing absorption in the range of 310 to 600nm are integrated to determine a total absorption quantity which relates to the actual and potential quantity of gum in the gasoline. This quality control technique will result in a refiner having more control over gum content at a hydrocarbon processing unit, such as a catalytic reformer.
