Beschreibung
Zusammenfassung:	The invention discloses a catalytic cracking method of straight-run diesel oil. The method comprises the following steps that: step 1, an acidic substance is added into the straight-run diesel oil, sothat alkaline nitride removal pretreatment can be carried out; step 2, a ZSM-5 type nano molecular sieve catalyst is put into a reactor so as to perform pretreatment; 3, after pretreatment is finished, the straight-run diesel oil and inert diluent gas are introduced into the reactor at the same time, so that a catalytic cracking reaction is conducted, and low-carbon olefin is generated. The acidic substance is one or two of groups consisting of sodium dihydrogen phosphate and potassium dihydrogen phosphate; and the addition amount of the acidic substance is 1-5% of the mass of the straight-run diesel oil; the inert diluent gas is one or more of groups consisting of nitrogen, helium and argon; and the molar ratio of the straight-run diesel oil to the inert diluent gas is 1: (0.1-1). The catalytic cracking method o
