Fuels Desulphurisation by Adsorbtion on Fe / Bentonite

Self Cite

Desulfurization of atmospheric distillation (DA) gasoline was performed by reactive adsorption on ZnO/ bentonite. The adsorbent was characterized by determining the distribution of particle sizes of zinc oxide powdered, adsorption isotherm and textural characteristics of granulated adsorbent. Adsorption experiments of atmospheric distillation gasoline were performed in continuous system at 280-320oC, 5-25 bar and volume hourly space velocities of 1-1.5 h-1. The adsorption on ZnO/ bentonite has been favored by increased pressure and operating temperature.

Desulfurisation of 1-dodecanethiol was performed by adsorption process on MgO adsorbent. The adsorbant was characterized by determining the adsorption isotherms, specific surface area, pore volume and average pore diameter. Adsorption experiments were performed in continuous system at 300-450�C, 5 atm and volume hourly space velocities of 1�2 h-1. Conversion of 1-dodecanetol increases with increasing temperature and decreasing volume hourly space velocities. It was identified the stage determinant of the process and a kinetic study of the desulfurization process was developed by reactive adsorption of 1-dodecanethiol on a magnesium oxide adsorbent.

“…Based on the concept of reactive adsorption, it was hypothesized to improve interactions between metal and support that could lead to improved activity and capacity to absorb sulfur [7]. Other reactive adsorption studies were performed as well as by Fe/ bentonite adsorbent [8]. In this paper we studied obtaining of a new adsorbents based on sand abrasive blasting grit for desulphurization of oil fractions.…”

Desulphurization by reactive adsorption was studied on sand abrasive blasting grit/ bentonite. The adsorbent was characterized by determining the composition, adsorption isotherms, specific surface area, pore volume and average pore diameter. Adsorption experiments were performed in continuous system at 260�300oC, 25 atm and volume hourly space velocities of 1-2 h-1. The efficiency of adsorption was evaluated at desulphurization of a synthetic reaction mixture and a catalytic cracking gas oil.
