Abstract:
There are hundreds of chemical components in spark ignition fuels, and so to make the testing and regulation manageable they are measured in categories by chemical group-type. These category group-types are based on molecular similarities that give them common performance behaviors. These tests are referred to as Detailed Hydrocarbon Analysis (DHA) which includes several test methods that measure different hydrocarbon subset or group-type categories. DHA identifies the important individual components in spark ignition fuels and other refinery light hydrocarbon process streams. Common refinery naphthas are virgin, alkylate, reformate, FCC and Coker, and finished spark ignition fuels. This technique is also referred to as PONA, PIONA, or PIANO analysis since specific test methods are measuring the group-type paraffins, isoparaffins, olefins, naphthenes, aromatics, and oxygenates. The DHA analysis helps optimize the production processes in addition to meeting the regulatory requirements. In this study, ZB-DHA-PONA is utilized for group type separation. It’s unique Engineered Self Cross-linking™(ESC) stationary phase provides low bleed and exceptional column life, extreme deactivation of the fused silica provides sharp peaks for polar and non polar compounds and the stationary phase is a true boiling point based separating phase. All these features provides the benefit of optimal separation of DHA critical pairs with symmetric peaks. Columns are available in high efficient dimension and are designed and Tested for Detailed Hydrocarbon Analysis. They provide excellent response and Peak Symmetry for Polar Oxygenates, suitable for DHA, PONA, PIONA, PIANO, and ASTM Methods (D5134, D5441, D5501, D6729, D6730, D6733).
