13X Molecular Sieve Rau Mercaptans Adsorption
Ntxiv nrog rau hydrogen sulfide, roj av cracking gas feem ntau kuj muaj qee yam ntawm cov organic sulfur. Qhov tseem ceeb ntawm kev txo cov ntsiab lus sulfur yog kom tshem tawm cov mercaptans thiab hydrogen sulfide hauv cov roj nyoos. Molecular sieves tuaj yeem siv rau adsorb qee cov tshuaj sulfur. Txoj cai adsorption feem ntau suav nrog ob yam:
1. Cov duab xaiv adsorption. Muaj ntau txoj hauv kev nrog cov pore loj thiab cov channel zoo sib xws hauv cov qauv molecular sieve, uas tsis tsuas yog muab cov cheeb tsam loj sab hauv, tab sis kuj txwv qhov kev faib ua feem ntawm cov molecules nrog cov pore loj loj nkag mus.
2. Polar adsorption. Vim yog cov yam ntxwv ntawm ionic lattice, qhov saum npoo ntawm molecular sieve yog cov polar heev, yog li nws muaj peev xwm adsorption siab rau cov molecules unsaturated, polar molecules thiab yooj yim polarized molecules. Molecular sieves feem ntau yog siv los tshem tawm mercaptans los ntawm cov nkev ntuj. Vim qhov tsis muaj zog polarity ntawm COS, uas zoo ib yam li cov qauv molecular ntawm CO2, muaj kev sib tw kev sib raug zoo ntawm cov adsorption ntawm ob ntawm molecular sieves nyob rau hauv muaj CO2. Txhawm rau kom yooj yim cov txheej txheem thiab txo cov cuab yeej siv peev, molecular sieve adsorption ntawm mercaptans feem ntau yog siv ua ke nrog molecular sieve lub cev qhuav dej.
Lub pore loj ntawm 3A, 4A, 5A thiab13X molecular sievesyog {{0}}.3nm, 0.4nm, 0.5nm thiab 1.0nm feem. Txoj kev tshawb nrhiav pom tias 3A molecular sieves tsis tshua muaj adsorbed mercaptans, 4A molecular sieves muaj peev xwm adsorption me me rau mercaptans, thiab 13X molecular sieves muaj zog adsorption muaj peev xwm rau mercaptans. Cov txiaj ntsig tau pom tias lub peev xwm adsorption thiab kev ua haujlwm adsorption tau nce ntxiv nrog qhov nce ntawm qhov pore loj.
