Study On The Synthesis Of COPNA Resin From FCC Slurry

COPNA resin is condensed polycyclic polynuclear aromatic resin is a thermosetting resin having a three-dimensional network structure, the resin has good heat resistance, resistance to friction performance and affinity for carbon material properties, is a new kind of functional material, has good market prospects. The synthetic raw material contains at least two aromatic rings of PAHs and their derivatives or their mixture. Aromatic hydrocarbons catalytic cracking oil slurry to tricyclic, tetracyclic in aromatic and aromatic side chain is short. The aromatic hydrocarbons can be used as the synthesis of COPNA resin material, which is a new way of utilization of FCC slurry oil.The extraction of aromatics in FCC slurry was enriched and the effects of several commonly used extracting agent on the oil slurry extraction effect, considering the option of furfural as extractant, the extraction temperature to 50℃, extraction time is 30 min, the solvent to oil ratio of 2:1. The enrichment of oil slurry before and after the four groups were detected, the aromatics content(mass fraction) increased from 48.7% to 67.6%. In this experiment, FCC slurry oil aromatic enriched components as raw material, TPA as crosslinking agent, PTS as the catalyst for COPNA synthesis resin, reaction conditions by changing reaction temperature, amount of crosslinking agent, amount of catalyst on the synthesis of COPNA resin and process conditions on the performance of. The softening point, carbon residue, solubility, thermal gravimetric analysis, to determine the optimum synthesis conditions is: reaction temperature 150℃, crosslinking agent content is 25%(mass fraction), the amount of catalyst is 5%(mass fraction).Analysis of B stage COPNA resin and curing resin obtained by different curing temperature showed that has a better COPNA resin curing condition is: 100℃ curing 6 hours, 200℃ curing 2 hours. Under these conditions the C order after curing of the resin is B order heat-resistant resin and carbon residue rate are improved to a great extent. The initial decomposition temperature increased from 300℃ to 400℃, and the residual carbon increased from 43% to 54%, and the effect of curing was good.
