A sample can be aged for an aging period in a quartz crystal microbalance apparatus, and a frequency value for the sample in the quartz crystal microbalance apparatus can be determined before and after the aging period to determine a frequency difference. This frequency difference can be correlated directly with the ability of a jet fuel fraction to satisfy a stability test standard, such as a jet fuel breakpoint stability. The methods can also include using a temperature profile during characterization that can reduce or minimize operator error during the characterization."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quartz crystal characterization of fractions derived from pre-refined crude and/or cracked streams","description":"Methods are provided for characterizing the stability of a distillate fraction using a quartz crystal microbalance apparatus, such as a distillate fraction derived at least in part from a pre-refined ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778241","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
