Sulfur Compounds Adsorption from Diesel Fuel by Zeolitic Tuff

Производитель: "LAP Lambert Academic Publishing"

The removal of organosulphur compounds (ORS) from diesel fuel is an important aspect of Jordanian s effort to reduce air pollution. Currently, the total sulphur content in Jordanian diesel fuel is 12000ppmw (1. 2%, wt/wt), but Jordanian government has recently introduced new restrictions that will reduce this level gradually to internationally acceptable levels. The zeolitic tuff (ZT), from Tlul Al-Shahba region, was characterised using various analytical techniques. It was found that the Freundlich model fitted the adsorption isotherms more accurately than the Langmuir model; indicating that the ZT had a heterogeneous surface. The Langmuir adsorption capacity values for the three particle size ranges (100 200), (300 400), and (500 600) _mwere 7. 15, 6. 32, and 5. 52 mg/g and the column capacities were 4. 45, 2. 57, and 1. 92 mg/g, respectively. The spent ZT was regenerated by washing with n-heptane with an efficiency of 81. 5%. Two adsorption mechanisms were investigated. One is that the... ISBN:9783848438372
