Determination of the carbon / hydrogen ratio in bitumen using prompt neutron gamma activation analysis

Marian Peticila, Vasile Tripadus, Liviu Craciun

Abstract


The paper presents a potential application of PGNAA method that allows the fast determination of colloidal index of bitumen compounds by a very fast analysis of hydrogen and carbon content. The H/C ratio thus determined is then correlated with colloidal index IC. The regression line is given by the empirical relation C/H = 5.9+ 34.1∗IC with a correlation factor R=0.99 and a standard deviation SD = 0.71. The perspectives of on-line applications are discussed.
