13x Molecular Sieve Desiccant Remove Mercaptans From Hydrocarbon Liquid Streams
Introduction
Zeolite 13X Molecular Sieve 13X is kind of sodium aluminosilicate, with a pore opening of 9-10 angstroms (0.9nm). The main component of the X-type molecular sieve is aluminosilicate, silicon-oxy and alumina tetrahedron to form an FAU-type structure, as know as NaX-type.
Molecular Formula Na2O·Al2O3·(2.8±0.2)SiO2 ·(6-7)H2O
SiO2/ Al2O3 ≈ 2.6-3.6
Normal Pore Opening 10 Angstroms (Å)
Regeneration temp. (°C) 200-315
Advantages High Stability; High Crush Strength; Large Water Absorption; Low Attrition; Deep Dehydration

Application
| Water, dioxide, hydrocarbons removal |
| General industrial gases drying |
| Gas purification in air separation process |
| Natural gas, liquefied petroleum, liquid hydrocarbons(propane, botane…) dehydration |
| Sulfur dioxide and mercaptan removal |
| General gas (such as compressed air, permanent gas) deeply drying |
| Ammonia synthesis gas drying and purification |
| Aerosol propellant desulfurization and deodorization |
| Carbon dioxide removal from cracked gas |
Regeneration:
Molecular sieve Type 13X can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 13X molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptan or CO2 levels below 2 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
Attention
Pls avoid damp and pre-adsorption of organic before running, or it must be reactivated.
