Determination and composition analysis of solid contents in FCC slurry oil
摘要:Ash analysis, filtration and centrifugation analysis were adopted to measure the content of solid particles in the FCC slurry oil from a residue fluid catalytic cracking (RFCC) unit in CNPC. The solid content measured by centrifugation method was about 2850μg/g, which was between those by the ash analysis and filtration methods. The centrifugation method results indicated that the strong adsorption between fine particles and the heavy components in the slurry oil was the key factor to obtain coke powder. Centrifugal method coupled with subsequent calcination could isolate and obtain certain amount of solid particles from the slurry oil. Then the solid particles and the original FCC catalyst were characterized by means of laser particle size analyzer, elemental analyzer, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy & energy spectrum analysis (SEM-EDS), etc. The fresh FCC catalyst was regular spherical and showed a size distribution in the range of 32-120μm, while the solid particles in the oil slurry were scattered and irregular with the particle size of 0.4-40μm, in which the fine catalysts were mostly between 1-30μm. The solid particles in FCC slurry oil mainly consisted of catalyst powder, coke powder, inorganic metal salts, such as alkali metal (K, Ca), antimony (Sb), and iron (Fe).
