How To Solve The Problem Of Activated Clay Production

- Apr 10, 2018 -

Activated clay is a product with many applications. He plays a very important role in everyone's life. Whether in the chemical industry or the food industry has his outstanding figure. In fact, the country's demand for him is very high because it is used in the food industry. His use of ingredients and content will affect everyone's health.

Animal and vegetable oil refining, used for decolorization and purification, removing harmful pigments, phospholipids, saponin, and cotton acid in oil, making it a high-grade cooking oil.

In the petroleum industry, it is used for the decolorization and purification of minerals such as oil, paraffin oil, wax oil, and kerosene, as well as the cracking of petroleum.

In the food industry, it is used as a clarifying agent for wines and sugar juices, stabilizing beer, saccharification, and sugar juice purification.

In the chemical industry, it is used as a catalyst, filler, desiccant, adsorbent, and wastewater treatment flocculant.

 In defense and medical hygiene, anti-drug and anti-drug agents and antidote can be made. With the development of society and science, the application of activated clay is becoming more and more widespread.

1. There is a certain degree of selectivity for the original soil of bentonite, not for all different types of bentonite, etc. The decolorization rate is ≥ 90% of high-efficiency activated clay, that is, some types of bentonite can only produce decolorization rate ≥ 80-85%. Ordinary activated clay or semi-efficient activated clay. The activity index temporarily fails to meet the requirement for H-type activity. Therefore, the scope of its use has been limited.

2, acidic wastewater treatment, the current amount of lime is too large.

3, high oil absorption rate. The decolorization amount of activated clay is 2%-5% of oil weight. The use of white clay to decolorize oils and fats entails entraining oil inevitably. The amount of entrainment is generally 20% to 50% of the amount of activated clay, thereby increasing the refining and cost. At present, a small number of companies use leaching to separate oil from activated waste white clay. However, due to the role of clay, the separated oil is black and cannot be discolored to a good color. Therefore, the domestic oil decolorization department hopes that the activated clay with low oil absorption rate.
