[Analysis of sulfur compounds in residue fluid catalytic cracking gasoline].
Sulfur compounds in residue fluid catalytic cracking (RFCC) gasolines from Refinery of SINOPEC Beijing Yanshan Company and Refinery of Shijiazhuang were analyzed by gas chromatograph connected with flame photometric detector (FPD) and atomic emission detector (AED). Twelve and 26 kinds of sulfur compounds were detected by AED in RFCC gasolines from Yanshan and Shijiazhuang respectively. Only 0 and 19 kinds of sulfur compounds were found by FPD in these two gasolines respectively. The experimental results demonstrated that AED is more sensitive and selective to sulfur compounds than FPD. It also indicated that thiophenes were the major sulfur compounds in the RFCC gasoline. In addition, mercaptan, sulfoether and disulfide species were found.
