Characterization of aromatic hydrocarbons and sulfur heterocycles in Saudi Arabian heavy crude oil by gel permeation chromatography and ultrahigh resolution mass spectrometry

Chemical Characterization Using Different Analytical Techniques to Understand Processes: The Case of the Paraffinic Base Oil Production Line

“…As can be seen in Figure 5, there is a relationship between the quantity of tailing after the main peak and the log of viscosity. These results, coupled with the amount of polyaromatics given by HPLC3, suggest that the aromatic compounds have a later elution time, as was already suggested by Panda et al [10] and by Alawani et al [5]. This result means that retention time, asymmetry of the curve, the percentage of aromatics, and viscosity are linked.…”

A three-dimensional semi-quantitative method to monitor the evolution of polycyclic aromatic hydrocarbons from vacuum gas oil feedstocks to lighter products

“…The second one was about the quantification of alkylated PAHs. It is well known that VGOs contain hydrocarbons which could have up to 50 carbon atoms [36][37][38]. To quantify these more or less alkylated compounds, their response factors had to be compared to their non-alkylated homolog compounds.…”

Opportunities and challenges for the application of post-consumer plastic waste pyrolysis oils as steam cracker feedstocks: To decontaminate or not to decontaminate?

“…Gel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC) which makes use of the different elution velocity of the respective analytes in a gel prior to detection on separate detectors. It has been frequently used for the analysis of pyrolysis oils and other high molecular weight hydrocarbons ( Choi et al, 2014 , Mercader et al, 2010 , Miskolczi et al, 2008 , Çit et al, 2010 , Arabiourrutia et al, 2012 , Hoekstra et al, 2011 , Miskolczi et al, 2009 , Williams and Williams, 1997b , Apicella et al, 2006 , Gargiulo et al, 2015 , Altgelt and Hirsch, 1970 , Panda et al, 2019 ).…”
