Abstract
Official abstract text for this publication.
The present disclosure provides a method for removing sulfur compounds from a fuel containing sulfur compounds. The method includes contacting the fuel with an adsorbent that comprises a carbonaceous material doped with nanoparticles of aluminum oxide to reduce the concentrations of the sulfur compounds. The carbonaceous material is at least one selected from the group consisting of activated carbon, carbon nanotubes, and graphene oxide, and the adsorbent has a weight ratio of C to Al in the range from 3:1 to 30:1, and a weight ratio of C to O in the range from 1:1 to 10:1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of reducing thiophene and dibenzothiophene in diesel fuel, comprising: contacting the diesel fuel with a fixed bed adsorbent, wherein the fixed bed adsorbent comprises a carbonaceous material doped with nanoparticles of aluminum oxide and the fixed bed adsorbent is in a cartridge and further comprises a zeolite, wherein the contacting forms a treated diesel fuel having a reduced concentration of the thiophene and the dibenzothiophene, wherein the carbonaceous material is graphene oxide, and wherein the fixed bed adsorbent has a weight ratio of C to Al in the range from 3:1 to 30:1, and a weight ratio of C to O in the range from 3:1 to 9:1. 2. The method of claim 1 , wherein the graphene oxide is doped with the nanoparticles of aluminum oxide by incipient wetness impregnation. 3. The method of claim 1 , further comprising regenerating the adsorption ability of the fixed bed adsorbent. 4. The method of claim 3 , wherein the regenerating comprises heating the fixed bed adsorbent at about 300-550° C. to remove the adsorbed thiophene. 5. The method of claim 1 , wherein the nanoparticles of aluminum oxide have a diameter ranging from about 30 nm to 80 nm.
