preparation example Construction

[0024] The preparation method flow process of the phenolic resin-based carbon molecular sieve of preferred embodiment of the present invention is as follows figure 1 shown, including the following steps:

[0025] 1. Treatment of phenolic resin raw materials: dry distillation of phenolic resin raw materials, and finely pulverize the phenolic resin raw materials. After finely pulverizing, the particle size is 4 microns;

[0026] 2. Apricot shell raw material processing: crush the apricot shell into apricot shell powder material, dry and grind the apricot shell powder material into apricot shell powder material;

[0027] 3. Molding: Put the powdery material of phenolic resin and apricot shell into the kneader, add the ingredients for stirring and kneading, and then put the material into the extruder for molding after kneading;

[0028] Among them, 50-60% of finely pulverized phenolic resin raw materials are put into 30-40% coal tar, 0-7% starch, 0-5% liquid phenolic resin, 0-6% ...

Embodiment 1

[0039] The phenolic resin raw material is dry-distilled, and the phenolic resin raw material is finely crushed. After finely crushing, its particle size is 4 microns; the phenolic resin raw material is dry-distilled so that it can obtain a balanced dryness, and the moisture content of the raw material must be guaranteed to be less than 5%;

[0040] crushing the apricot shell into apricot shell powder material, drying and grinding the apricot shell powder material into the apricot shell powder material;

[0041] Put the powdery material of phenolic resin and the powdery material of apricot shell into a kneader, add ingredients to carry out stirring and kneading, and after kneading, put the material into an extruder for molding;

[0042] Among them, 50% of the finely pulverized phenolic resin raw material is put into a binder composed of 30% coal tar, 7% starch, 2% liquid phenolic resin, and 1% wood pulp by mass percentage, and kneaded Extrude into a cylindrical shape; mix apric...

Embodiment 2

[0046] The phenolic resin raw material is dry-distilled, and the phenolic resin raw material is finely crushed. After finely crushing, its particle size is 4 microns; the phenolic resin raw material is dry-distilled so that it can obtain a balanced dryness, and the moisture content of the raw material must be guaranteed to be less than 5%;

[0047] crushing the apricot shell into apricot shell powder material, drying and grinding the apricot shell powder material into the apricot shell powder material;

[0048] Put the powdery material of phenolic resin and the powdery material of apricot shell into a kneader, add ingredients to carry out stirring and kneading, and after kneading, put the material into an extruder for molding;

[0049] Among them, 60% of the finely pulverized phenolic resin raw material is put into a binder composed of 40% coal tar by mass percentage, and is kneaded and extruded into a cylindrical shape; the apricot shell powder material, phenolic resin, polyet...

Abstract

The invention relates to a preparation method of a phenolic resin based carbon molecular sieve. The preparation method comprises steps as follows: 1, phenolic resin raw material processing: a phenolic resin raw material is subjected to dry distillation and fine crushing, and the particle diameter of the phenolic resin raw material after fine crushing is 4 mu m; 2, apricot shell raw material processing: apricot shells are crushed into an apricot shell powder material, and the apricot shell powder material is dried and pulverized into an apricot shell micro-powder material; 3, forming; 4, carbonizing: the material after forming is placed in a converter, the temperature is increased to 700-750 DEG C under the nitrogen protection for carbonization, the temperature increase process comprises two stages, the temperature increase speed of the first stage is 5-10 DEG C/min, the temperature increase speed of the second stage is 15-20 DEG C/min, and the constant temperature is kept for 30-40 min after the temperature is increased to 700-750 DEG C; 5, deposition: the phenolic resin based apricot shell carbon molecular sieve is obtained. According to the preparation method of the phenolic resin based carbon molecular sieve, the product performance is greatly improved, carbonization and deposition processes are combined, and 35% of energy can be saved.

Description

technical field [0001] The invention relates to the technical field of carbon molecular sieve preparation, and more specifically, relates to a preparation method of a phenolic resin-based carbon molecular sieve. Background technique [0002] As a new type of adsorbent product, carbon molecular sieve is mainly used to separate air and enrich nitrogen (or oxygen); it can be widely used in the preservation and storage of food, fruit, grain, tea, and Chinese medicinal materials, nitrogen-based treatment of metal heat treatment, Electronic product processing, coal mine fire extinguishing, petrochemical industry, etc. [0003] The current carbon molecular sieves are all produced from raw coal. First of all, the raw coal should be selected and treated with acid. It is required to control the ash content below 5% and the volatile content above 35%. The tar is extruded together, the diameter of the formed particles is 2-2.5 mm, and then the formed product is placed in a drying oven...
