low-aluminium molecular sieve catalytic cracking catalyst - Names and Identifiers
low-aluminium molecular sieve catalytic cracking catalyst - Introduction
Low alumina molecular sieve catalytic cracking catalyst is an important catalyst in oil catalytic cracking technology. The following is an introduction to the nature, use, preparation and safety information of low aluminum molecular sieve catalytic cracking catalysts:
Nature:
The low aluminum molecular sieve catalytic cracking catalyst is a heteropoly metal oxide composite, and its components usually include silicon, aluminum, and other metals such as potassium, calcium, and magnesium. It has high specific surface area and rich acid sites, which makes it have good catalytic activity and selectivity.
Use:
Low aluminum molecular sieve catalytic cracking catalysts are mainly used in petroleum catalytic cracking units to convert heavy petroleum feedstocks into light petroleum products. Low alumina molecular sieve catalytic cracking catalyst has high catalytic activity, good selectivity and stability, which can effectively improve the yield and quality of petroleum products and meet different market demands.
Preparation Method:
The preparation method of low aluminum molecular sieve catalytic cracking catalyst generally uses sol-gel method, vapor deposition method and other methods. First, a suitable Silicon source, aluminum source and other metal sources are selected and dissolved in a suitable solvent to obtain a precursor solution. Then, by adjusting the pH value, temperature and other conditions, the precursor in the solution is gradually converted into gel. Finally, the gel is dried, calcined and other treatments to obtain the finished low aluminum molecular sieve catalytic cracking catalyst.
Safety Information:
When using low aluminum molecular sieve catalytic cracking catalyst, the following safety precautions should be paid attention:
1. The catalyst should be stored in a dry and sealed environment to avoid contact with harmful substances such as moisture and oxygen to prevent loss of activity.
2. When using the catalyst, it is necessary to ensure good ventilation conditions to avoid inhalation of catalyst dust.
3. The catalyst is corrosive to a certain extent, so it is necessary to avoid contact with skin and eyes to avoid irritation or damage.
4. In the process of using the catalyst, it is necessary to comply with relevant safety operation procedures and personal protective measures, such as wearing protective clothing and protective glasses. In case of discomfort or accident, stop the operation immediately and seek medical attention as soon as possible.
