PROCEDE DE QUANTIFICATION NUMERIQUE EN LIGNE ET EN TEMPS REEL DE LA VALORISATION POTENTIELLE D'UNE CHARGE DE REFORMAGE CATALYTIQUE PAR ANALYSE SPECTROPHOTOMETRIQUE PROCHE INFRAROUGE DE CETTE CHARGE RECUE A L'ALIMENTATION DU REFORMEUR

摘要

Method for numerical on-line, real-time quantification of the potential upgrading of a catalytic reforming charge entering a catalytic reforming unit, by means of a spectrophotometer, by measuring the absorbence in the spectral band from 12500 to 3840 cm<-1> (0.8 to 2.6 microns) and by selecting within this band a certain number of frequencies in order to establish statistical correlations with the desired characteristics and by directly calculating the desired values by applying a correlative relationship with the measured absorbence values (D@).
