Abstract
The present invention discloses a kind of for gasoline, coal tar hydrorefining desulfurization, denitrification catalyst and preparation method thereof, including catalyst carrier and carrier loaded active material, through hole centered on described catalyst, 1~2mm of diameter it is cylindric, its voidage is 1.2~1.6 times of the real core catalyst carrier of same equivalent diameter, and active component is 0.2~0.5 times of the other structures catalyst of same equivalent diameter；The material of described catalyst carrier includes the mixture or the mixture of aluminum oxide series material and titanium oxide series material of aluminum oxide series material or aluminum oxide series material and silica series material, the active material of load contains cobalt, nickel, molybdenum, zinc, one or more in phosphorus.The voidage of the catalyst is 1.2~1.6 times of the real core catalyst carrier of same equivalent diameter, and the amount of active ingredients for being used is also 50~80% of other catalyst under same volume, and the usage amount of catalyst activity component is greatly saved, and has saved resource.
Description
Technical field
Field is manufactured the present invention relates to the catalyst used by oil refining industry, is specifically related to a kind of for gasoline, coal
Hydrogenation of tar refining desulfurization, catalyst of denitrogenation and preparation method thereof.
Background technology
Also more and more strong to asking for for natural resources with the progress of human civilization, the destruction to environment is also increasingly serious,
And most of resources be it is limited, it is non-renewable, therefore meet permanently effective utilization and conservation of nature ring of the mankind to resource
Border is the very urgent responsibilities and obligations of owner.We must accomplish to increase income and decrease expenditure, and take exploitation new technology, improve resource profit
With measures such as rates, it is intended to economize on resources and be reduced or avoided the destruction to environment, Blue Sky is left to descendants.
And oil refining industry be natural resources exploitation using and environmental pollution than more serious industry；Use is urged more at present
Agent carries out the removing of pollutant, to weaken the pollution to environment；Particularly it is used for gasoline, coal tar hydrorefining desulfurization, takes off
The catalyst of nitrogen, the composition of such catalyst mainly includes carrier and active material, and it is straight that carrier structure therein is mainly equivalent
The bar shaped reality core body of 0.5~3mm of footpath, such as " clover " type, cylindrical type etc., the catalyst carrier technology of the series structure into
It is ripe, industrialize for many years, there is its advantage, also there is its inferior position, advantage is technology maturation, simple production process；Inferior position is manufacture
Catalyst buildup voidage is small, with the catalyst under the conditions of equivalent responses, required more active components.
The content of the invention
Above-mentioned deficiency of the present invention for prior art, there is provided one kind is used for gasoline, coal tar hydrorefining desulfurization, denitrogenation
Catalyst, the voidage of the catalyst is 1.2~1.6 times of the real core catalyst carrier of same equivalent diameter, the work for being used
Property group component is also 50~80% of other catalyst under same volume, and the use of catalyst activity component is greatly saved
Amount, has saved resource.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：One kind is for gasoline, coal tar hydrogenating essence
Desulfurization processed, denitrification catalyst, including catalyst carrier and carrier loaded active material, through hole centered on described catalyst,
1~2mm's of diameter is cylindric, and its voidage is 1.2~1.6 times of the real core catalyst carrier of same equivalent diameter, active component
It is 0.2~0.5 times of the other structures catalyst of same equivalent diameter；The material of described catalyst carrier includes aluminum oxide series
The mixture or aluminum oxide series material and titanium oxide series material of material or aluminum oxide series material and silica series material
The mixture of material, the active material of load contain one kind in cobalt (Co), nickel (Ni), molybdenum (Mo), zinc (Zn), phosphorus (P) etc. or
It is various.
Described aluminum oxide series material includes but is not limited to the one of the aluminum oxide series material such as boehmite, Alumina gel
Plant or various powders for mixing composition.
Described silica series material is referred to but is not limited to Ludox, and aerosil etc. is mixed for one or more
The material being combined into.
The present invention also provide it is a kind of it is above-mentioned for gasoline, coal tar hydrorefining desulfurization, denitrification catalyst preparation method,
Specific step includes：
(1) it is 80~100 according to weight ratio by aluminum oxide and silica series material：0~20 ratio is made into mixing
Material, it is the 0.5~10% of compound weight to aid in binding agent, and it is the 35~70% of compound weight to add water, and peptizing agent is mixed
The 0.5~5% of material weight is closed, pug is mixed into；
(2) using Application No. 2016109656335, entitled《A kind of miniature catalyst carrier mould, the mould

Specific embodiment
The present invention is described in further detail below by embodiment, but the present invention is not limited solely to following examples.
Embodiment
(1) boehmite original powder 1kg, methylcellulose 30g are taken, batch mixer batch mixing is put into the lump and is added water after 5 minutes
550g and 20g nitric acid, continues batch mixing until powder all becomes pug for this；
(2) in the pug input pressure extruder for completing step (1), by Application No. 2016109656335, invention
It is entitled《A kind of miniature catalyst carrier mould, the manufacture craft of the mould and the method that carrier is prepared using the mould》Middle institute
The mould extrusion molding stated；
Specifically, as shown in accompanying drawing 1-5, the miniature catalyst carrier mould in Application No. 2016109656335, the mould
Tool includes formpiston 1 and former 2, and described formpiston and one end of former are laminated；Described formpiston is axially disposed some
Enter mud hole 3 and large knitting needle accommodating hole 4, be plugged with described large knitting needle accommodating hole and lead mud rod 5；Described former is axially arranged some
Forming hole 6, when one end of formpiston and former is laminated, described forming hole and large knitting needle accommodating hole coaxial line and described
Mud rod is led through forming hole and large knitting needle accommodating hole；Described former axially inwardly sets fluted 7, institute with the end face of formpiston pressing
The groove stated forms interlayer gap 8 with the end face of formpiston；Internal diameter of the described external diameter for leading mud rod less than forming hole.Using above-mentioned
Structure, one end of formpiston and former is laminated, and then will be led mud rod and is inserted into forming hole from large knitting needle accommodating hole one end, and
Termination protrudes from forming hole；Then the catalyst carrier pug containing active material is entered by press from mud pore pressure is entered, is entered
Formed to groove and be sufficiently mixed in interlayer gap, then extruded from forming hole, obtain hollow catalyst carrier, this structure
Carrier is set due to boring, can cause that catalysis area becomes big, improves catalytic efficiency, reduces cost so that material use
Rate is more abundant.
