Q & A > Question Details
ASTM D2887 method claims to be applicable for petroleum fractions having FBP up to 538 C.
But, as per method, GC is typically operated within range of 360-390 C.
So, is it possible to vaporize HCGO (370-530 C) sample (0.5-1 micro liter) at this operating temperature and hence, evaluate the TBP profile of HCGO?

You can use ASTM D 7162, is a high temperature simdistillation method goes up to 720 Deg.C . Can ask the vendor for simdist to ASTM D 1160 distillation conversion software or TBP software. Another method ASTMD 6352 is also there , which is also a high temperature simdist method. These both methods can be used for HCGO .

I'm not familiar with the details of the analytic method for D2887. My understanding is that D2887 is a "High Temperature Simulated Distillation" or "High Temperature SimDist." In the past, D86 was used for fractions lighter than gas oil, and D1160 was used for gas oil fractions and heavier. Now, my customers typically use D2887 for diesel, gas oil, and heavier. Its use is widespread.
It's important to realize that D2887 is typically reported in mass pct whereas TBP is typically reported in volume pct.
Hysys will convert it for you. If you enter it as D2887, it will estimated TBP.
