A kind of heavy oil thermal Cracking catalyst and preparation method thereof
Technical field
The present invention relates to catalyst material, particularly relate to a kind of heavy oil thermal Cracking catalyst and preparation method thereof.
Background technology
Rare earth element can significantly improve activity and the stability of catalyst after being introduced in Cracking catalyst, raw material is greatly improved Oil cracking conversion rate, increases gasoline and the productivity of diesel oil, the most also has that crude charging capacity is big, yield of light oil is high, catalyst Low, good selective is lost.But the heavy oil thermal Cracking catalyst life-span introducing rare earth element in prior art falls short of, The diesel-fuel cetane number obtained is not high enough.
Summary of the invention
The present invention, for the heavy oil thermal Cracking catalyst obtaining a kind of life-span length, diesel cetane-number is high, the invention provides one Plant heavy oil thermal Cracking catalyst and preparation method thereof.
A kind of heavy oil thermal Cracking catalyst, including following raw material, in parts by mass: lanthana 3～5 parts, ceria 20 ～30 parts, sodium tungstate 14～25 parts, aluminium silicate 8～15 parts, acetic acid 18～30 parts.
The preparation method of described a kind of heavy oil thermal Cracking catalyst, comprises the steps of
(1) lanthana, ceria, sodium tungstate, aluminium silicate are simultaneously introduced in ball mill, grind 1～2 hour, powder diameter It is 200～300 mesh；
(2) adding in acetic acid by the powder obtained, stirring at normal temperature is reacted 5-8 minute, filters and removes filtrate, it is thus achieved that filtering residue, spends Ionized water cleans, and cleans 1-3 time, dries, it is thus achieved that mixture of powders under the conditions of filtering residue is placed in 33-42 DEG C；
(3) being placed in mixing device by mixture of powders, each powder is co-deposited and uniformly mixes；
(4) being placed in electric furnace by above-mentioned uniform mixed powder, be sintered in inert gas shielding atmosphere, temperature maintains Stage is divided into two benches, first stage 520 DEG C, second stage 600 DEG C, and each maintenance stage sintering time is 2-3 hour, sintering After i.e. obtain heavy oil thermal Cracking catalyst.
Preferably, described heavy oil thermal Cracking catalyst is made up of following components proportioning by weight: lanthana 5 parts, two Cerium oxide 22 parts, sodium tungstate 18 parts, aluminium silicate 12 parts, acetic acid 25 parts.
Preferably, in step (1) by lanthana, ceria, sodium tungstate, aluminium silicate grind after powder diameter be 230 mesh.
Beneficial effects of the present invention: the heavy oil thermal Cracking catalyst of the present invention adds rare earth element lanthana, ceria, Coordinate sodium tungstate, aluminium silicate, through heavy oil thermal Cracking catalyst life-span length prepared by the process such as efflorescence, high-temperature calcination, diesel oil 16 The advantage that alkane value is high.
