The property of raw materials for needle coke production directly affects the quality of needle coke.Therefore,it is proposed to convert bicyclic aromatic hydrocarbons in catalytic cracked diesel(LCO)into tricyclic and tetracyclic aromatic hydrocarbons to prepare high-quality raw materials for needle coke,thereby promoting"oil to chemicals".The existing polycondensation technologies for bicyclic aromatic hydrocarbons are described in detail,and the catalytic polycondensation reaction mechanism for naphthalene is comprehensively analyzed.The applications and research progress of different catalysts for naphthalene polycondensation are summarized and discussed,including the effects of catalyst properties on catalytic activity,product selectivity,and recycling methods.Besides,the industrialization application to realize the targeted conversion of LCO is analyzed.It is proposed that the mechanism of catalytic naphthalene condensation over solid super acid shall be deeply investigated in the future.The catalysts with high activity and selectivity for naphthalene condensation will be prepared based on the theoretical guidance.
