Preparation process used for catalyst carrier activated carbon and capable of fully utilizing crushed bamboo materials

Abstract

The invention discloses a preparation process used for catalyst carrier activated carbon and capable of fully utilizing crushed bamboo materials. The preparation process comprises the following steps that: S1, pre-sorting is performed, specifically, the crushed bamboo materials are divided into two batches through a 50-mesh screen, and the two batches are respectively put into a crushed material box and a block material box; S2, soaking and kneading are performed; S3, carbon activation treatment is performed, specifically, materials processed by two kneading machines are fed into a rotary kiln, the rotating speed of the rotary kiln for activating the crushed bamboo materials smaller than 50 meshes is 2-4 revolutions / min, the ignition loss is smaller than 50%, microporous activated carbon is obtained, the rotating speed of the rotary kiln for activating the crushed bamboo materials larger than 50 meshes is 5-10 revolutions / min, the ignition loss is larger than 75%, and macroporous activated carbon is obtained; S4, acid pickling is performed, heavy metals in the activated carbon are removed, and the pH value of the activated carbon is adjusted at the same time; S5, drying is performed; S6, granules are screened; S7, powder is ground; and S8, the powder is packaged. The crushed bamboo materials are divided into two types according to the size and are respectively processed, so that the macroporous activated carbon and the microporous activated carbon are simultaneously processed, the high yield of each type of activated carbon is ensured, and the full utilization of the crushed bamboo materials is realized.

Description

technical field [0001] The present invention relates to a kind of preparation technology of activated carbon, more specifically, it relates to a kind of preparation technology of catalyst carrier activated carbon which makes full use of bamboo scraps. Background technique [0002] Activated carbon is a product highly dependent on resources and energy. It can be used not only as a purification material, but also as a carrier of activated carbon. Due to the constraints of the shortage of raw material resources, the production growth of activated carbon is greatly restricted and cannot meet the growing demand of the market; however, a large amount of bamboo scraps can be produced in the process of bamboo processing, which has not yet been scientifically, rationally and effectively developed and developed. Comprehensive utilization has affected the improvement of the added value of the bamboo industry. If the biological characteristics of bamboo are utilized, it is prepared int...
