Abstract
It is the important raw and processed materials in chemical industry containing molybdenum-nickel hydrogenation catalyst.The technological process of production containing molybdenum-nickel hydrogenation catalyst is：Alumina powder and water, reagent nitric acid, citric acid, sesbania powder etc. according to specific ratio be sufficiently mixed and pinch it is ripe after, into banded extruder, be extruded into the wet bar with certain external diameter and shape.Wet bar enters dry zone or drying box, is dried at a temperature of 120~150 DEG C, and dry bar is obtained after removal surface water.（Nitric acid in addition acid solution tank, then with being pumped into the acid solution measuring tank of factory building, is added in preparing tank by measuring tank and is allocated under negative pressure state）.Dry bar is calcined more than 2 hours by after trimmer shaping, calcining kiln being evenly supplied to batcher under 550~850 DEG C of hot environments, obtains the r-Al2O3 carriers with certain pore structure and catalysis activity.
Description
(1) main chemical reactions molecular weight explanation：Ammonium molybdate：1235.68 nickel nitrates：290.81 molybdenum trioxides：
143.94；Nickel oxide：The reaction that 74.69 carrier calcination processes occur：
The chemical reaction ammonium molybdate that occurs is decomposed reaction when finished product is calcined：

Decompose reaction：
The technological process of production containing molybdenum-nickel hydrogenation catalyst is sketched alumina powder and water, reagent nitric acid, citric acid, sesbania powder etc. and is pressed
According to specific ratio be sufficiently mixed and pinch it is ripe after, into banded extruder, be extruded into the wet bar with certain external diameter and shape.Wet bar
Into dry zone or drying box, dried at a temperature of 120~150 DEG C, dry bar is obtained after removal surface water.（Nitric acid is negative
Under pressure condition, in addition acid solution tank, then with being pumped into the acid solution measuring tank of factory building, preparing tank is added to by measuring tank
In allocated）.Dry bar by after trimmer shaping, calcining kiln being evenly supplied to batcher, at 550~850 DEG C
It is calcined more than 2 hours under hot environment, obtains the r-Al2O3 carriers with certain pore structure and catalysis activity.By one
Quantitative nickel nitrate, ammonium molybdate water dissolves, are configured to dipping solution by a certain percentage, with vacuum rotating impregnator by carrier
Certain hour is sufficiently mixed and kept with dipping solution, carries out saturation dipping.The logical steam of impregnator chuck is to the product by dipping
Product are dried, and the surface water in catalyst carrier is evaporated under condition of negative pressure, and the raw material of active component is just attached to r-
In the hole of Al2O3 carriers.At a temperature of 450~500 DEG C, high temperature work is carried out to bar after dipping with guipure calcining kiln
Change, active component raw material salt is resolved into oxide, and with r-Al2 carriers be combined into it is with specific crystalline form, with specific
The finished catalyst of pore structure and specific surface.
