Abstract
The invention relates to a catalyst production method which is characterized by comprising the following steps: (1), preparing raw materials in parts by mass as follows: 5 parts of acetic acid, 4 parts of sodium hydroxide, 3 parts of propylene glycol, 10 parts of oxalic acid and 5 parts of magnesium oxide; and (2), pouring acetic acid and oxalic acid into a beaker, heating acetic acid and oxalic acid to 30 DEG C, then adding sodium hydroxide, propylene glycol and magnesium oxide, heating the mixture continuously to 60 DEG C within 20 min while stirring, performing heat insulation for 20 min, and then cooing the mixture to the room temperature to obtain a catalyst product.
Description
Technical field
The present invention relates to a kind of catalyst manufacturing process, belong to catalyst technical field.
Background technology
Can change the chemical reaction rate of reactant in chemical reaction, can improve and also can reduce, and the material that the quality of itself and chemical property all do not change before and after chemical reaction is catalyst, is also catalyst.According to statistics, about have in the chemical process of 80% ~ 85% and used, as ammonia, sulfuric acid, the synthesis of nitric acid, ethene, the polymerization of propylene.
Catalyst occupies extremely important status in modern chemical industry, almost has chemical products more than half all to adopt catalyst in production process.Such as, Ammonia Production adopts iron catalyst, and gas washing in SA production adopts vanadium catalyst, in the polymerization of ethene and the production with three large synthetic materials such as butadiene rubber, all adopts different catalyst.According to statistics, the chemical process of 80% ~ 85% is about had to use catalyst, as the synthesis of ammonia, sulfuric acid, nitric acid, the polymerization of ethene, propylene, styrene etc., the comprehensive utilization of oil, natural gas, coal, etc., object accelerates reaction rate, enhances productivity.In the field such as the utilization of resources, energy development, medicine manufacture, environmental protection, catalyst also fully develops talents, and scientist is just exploring suitable catalyst to having new breakthrough in some aspects in these fields.Catalyst is obviously participated in reaction, and just as a reaction intermediary, before the reaction, total amount is constant, and makes to accelerate or a kind of material improving constantly along with industrial expansion and living standard of slowed down reaction speed.But the method for producing catalyst is in the market a lot, and these method production efficiencys are lower, and the catalyst effect produced is unsatisfactory.Therefore, a kind of new technical scheme of exigence solves the problems of the technologies described above.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention discloses a kind of catalyst manufacturing process, this catalyst manufacturing process cost is lower, and operating efficiency is high, and the waste gas after process can reach the relevant emission standards of environmental administration, can not production secondary pollution.
To achieve these goals, technical scheme of the present invention is as follows, a kind of catalyst manufacturing process, it is characterized in that, described catalyst manufacturing process is specific as follows, 1) raw material is prepared, mass fraction is as follows, acetic acid 5 parts, 4 parts, NaOH, propane diols 3 parts, oxalic acid 10 parts, 5 parts, magnesia, 2) first by acetic acid, oxalic acid is poured in beaker and is heated to 30 DEG C, add NaOH again, propane diols and magnesia, continue heating, heat while stirring, 60 DEG C are heated in 20 minutes, be incubated 20 minutes, then room temperature is cooled to, catalyst prod can be obtained.
Relative to prior art, advantage of the present invention is as follows: 1) whole technical scheme is simple, and cost is lower; Reduce entreprise cost: 2) this production method efficiency is high, effective, and whole production process is pollution-free, environmental protection; 3) the method operates comparatively safe, has no side effect to operating personnel; 4) this manufacture method compared is simple, and handling safety, the product catalytic efficiency of production is high, is convenient to apply on a large scale.
Detailed description of the invention
In order to deepen, to understanding of the present invention and understanding, below in conjunction with detailed description of the invention, to illustrate the present invention further.
embodiment 1:
A kind of catalyst manufacturing process, described catalyst manufacturing process is specific as follows, and 1) prepare raw material, mass fraction is as follows, acetic acid 5 parts, 4 parts, NaOH, propane diols 3 parts, oxalic acid 10 parts, 5 parts, magnesia, 2) first acetic acid, oxalic acid are poured in beaker and is heated to 30 DEG C, add NaOH, propane diols and magnesia again, continue heating, heat while stirring, in 20 minutes, be heated to 60 DEG C, be incubated 20 minutes, then be cooled to room temperature, can catalyst prod be obtained.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technical scheme be made up of above technical characteristic.
Claims (1)
1. a catalyst manufacturing process, it is characterized in that, described catalyst manufacturing process is specific as follows, 1) raw material is prepared, mass fraction is as follows, acetic acid 5 parts, 4 parts, NaOH, propane diols 3 parts, oxalic acid 10 parts, 5 parts, magnesia, 2) first acetic acid, oxalic acid are poured in beaker and is heated to 30 DEG C, add NaOH, propane diols and magnesia again, continue heating, heat while stirring, 60 DEG C are heated in 20 minutes, be incubated 20 minutes, be then cooled to room temperature, can catalyst prod be obtained.
