Description
Technical field
The present invention relates to a kind of preparation method of carrier material, a kind of preparation method who contains the catalyst carrier material of molecular sieve and amorphous aluminum silicide specifically is especially for the preparation method of the catalyst carrier that contains molecular sieve-amorphous aluminum silicide of hydrocracking catalyst.
Background technology
In general, hydrocracking catalyst is a kind of catalyst that has simultaneously cracking function and hydrogenation-dehydrogenation functionality.The cracking function is to be provided by acid carrier, and the hydrogenation dehydrogenation functionality is to be provided by reactive metal, the acid carrier major part is take aluminium oxide or amorphous aluminum silicide as carrier, be equipped with a certain amount of molecular sieve, its basic preparation process is first aluminium oxide or silicon-containing alumina and molecular sieve and other auxiliary agent directly to be mixed, then carry out moulding, drying and roasting, final impregnating metal and activation.Amorphous aluminum silicide requires itself must have enough large specific area and pore volume as one of important component of catalyst carrier, with the carrying active metal component; Molecular sieve is mainly the acidic cleavage component, and for catalyst, cooperation both is most important, only has both coordinative roles, the catalytic action of competence exertion the best.In prior art, because molecular sieve adds by physical mixed, can not be in other carrier material of catalyst Uniform Dispersion, affect the reactivity worth of catalyst.
CN1110304A discloses the preparation method of the siliceous and phosphorus oxidation aluminium of a kind of macropore.In the preparation process of this aluminium oxide, silicon and phosphorus add with substep plastic method, can make like this silicon and phosphorus major part be dispersed in alumina surface, aluminium oxide aperture and pore volume are improved, but owing to having added more phosphorus, B acid amount greatly reduces to make the acid of alumina surface measure particularly, and acid strength obviously reduces, and its application is subject to certain restrictions.CN1184703A discloses a kind of preparation method of silicon-containing alumina.This silicon-containing alumina is a kind of alumina globule that silica is 5wt%～15wt% that contains, its preparation characteristic is that the silicon-containing alumina wet bulb after moulding carries out low temperature drying in containing the atmosphere of ammonia, the character of the alumina balls that obtain has obtained some improvement, but some defectives due to balling-up aspect self, make this forming process complicated, product yield is low, the shortcomings such as preparation cost height.EP0339640 discloses a kind of method for preparing titanium-contained aluminum oxide with coprecipitation, because coprecipitation itself exists the problem that body is detained mutually, causes titanium dioxide can not give full play to the facilitation of aluminium oxide.Require two or more species co-precipitation under certain condition due to co-precipitation, this condition to co-precipitation has proposed very harsh requirement, that is to say, even under certain conditions, two kinds of materials can precipitate simultaneously, but this condition may not be also all best to two kinds of materials, and the method has characteristics and the shortcoming of itself thus.CN1060977A discloses a kind of preparation method who contains the ultrastable of amorphous aluminum silicide, Alusil is introduced in the NaY zeolite, then obtained containing the USY zeolite of amorphous aluminum silicide through conventional ammonium ion exchange, hydrothermal calcine process.The main deficiency of the method is: the part amorphous aluminum silicide is easy to enter in molecular sieve pore passage, not only stop up molecular sieve pore passage, pore volume and the specific area of molecular sieve have been reduced, but also covered the part acid site, affected the catalytic performance of molecular sieve, also affect simultaneously the modification process of molecular sieve, the catalytic performance of molecular sieve and amorphous aluminum silicide can not be played one's part to the full.
CN200610134151.1 discloses a kind of preparation method who contains the carrier material of molecular sieve and amorphous aluminum silicide.Molecular sieve in carrier is introduced in amorphous aluminum silicide plastic process.In the method, reuniting can appear in silica-alumina supports in molecular sieve, and perhaps molecular sieve and amorphous aluminum silicide enter mutually the other side's duct, have blocked the part duct and have covered a part of acid site, makes carrier specific area, pore volume and acidity increase limited.
