Adsorbent loaded with alkali active components, preparation method of adsorbent loaded with alkali active components and deep dechlorination method

Abstract

The invention provides an adsorbent loaded with alkali active components, a preparation method of the adsorbent loaded with alkali active components and a deep dechlorination method. In percentage byweight, per 100% of the adsorbent loaded with alkali active components comprise 30-70% of molecular sieve, 10-50% of active alumina and the balance of alkali active metal components. The preparation method of the adsorbent loaded with alkali active components comprises the following steps of mixing the molecular sieve, an adhesive-bonding agent and a pore-forming agent, molding the mixture by performing kneading, and carrying out drying and calcining so as to obtain an adsorbent carrier; immersing the adsorbent carrier in an aqueous solution of alkali active metal components, and carrying outfiltering, drying and calcining so as to obtain the adsorbent loaded with alkali active components. Being applied during dechlorination process of ionic liquid alkylated oil adopting fixed bed technology, the adsorbent loaded with alkali active components provided by the invention shows excellent dechlorination effects; moreover, regeneration process of the adsorbent is simple, effective, low in energy consumption and free of hydrogen. Ionic liquid alkylated oil underwent dechlorination according to the process can be directly used as gasoline-blending oil.

Description

technical field

[0001] The invention belongs to the technical field of dechlorination of alkylated oil, and in particular relates to an adsorbent loaded with alkali active components, a preparation method thereof, and a method for deep dechlorination of ionic liquid alkylated oil by using the adsorbent. Background technique

[0002] Alkylate oil is a common high-octane gasoline blending component. It has the advantages of high octane number, good sensitivity, low vapor pressure, wide boiling point range, no olefins and aromatics, and clean combustion. chain reaction of alkanes and alkenes. The current gasoline standards continue to improve, and the restrictions on the content of aromatics and olefins in gasoline are gradually becoming stricter, and the importance of alkylated oil is becoming increasingly prominent. The traditional alkylation reaction is mainly divided into sulfuric acid alkylation technology and hydrofluoric acid alkylation technology, but both of them have...
