METHOD FOR THE DIRECT DETERMINATION OF PHYSICAL PROPERTIES OF HYDROCARBON PRODUCTS |
摘要 |
The properties of a product and/or the yield of the product from a hydrocarbon conversion or separation process are determined from the NIR (Near Infra Red) spectrum of the feedstock by a method which comprises the following steps: (a) determining with an IR spectrometer the absorbance of the feedstock at a certain number of frequencies in the spectral range 16667 to 3840 cm<-><1>, preferably 12500 to 3840 cm<-><1>, most preferably 4760 to 4999 cm<-><1> starting from a defined base line, and (b) determining the property by applying a correlation between the property and the absorbance values, the correlation being determined experimentally by multivariate regression, depending on the type of spectrometer used, the property required, and the frequencies used. |
