Adsorptive Removal of Nitrogen, Sulfur, and Aromatic Compounds from Gas Oil by Poly(glycidy methacrylate) Using Two Kinds of Graft Polymerization Methods

Abstract

Based on a polyglycidyl methacrylate-co-ethylene glycol dimethacrylate copolymer (PGMA-co-EGDMA), nitrogen, sulfur, and aromatic compounds were removed from light and heavy gas oil feeds. The method in which PGMA-co-EGDMA is synthesized can influence the textural and chemical characteristics of the polymer and thus its adsorption capacity. Studies have shown that using cerium initiated graft polymerization in PGMA-co-EDGMA synthesis can improve the adsorption capacity of the polymer. In this work, nitrogen, sulfur, and aromatics removal capacity of (PGMA-co-EGDMA) polymer incorporated with tetranitrofluorenone (TENF) via 1,3 diaminopropane (PDA) using cerium initiated graft polymerization were compared with the same polymer without using cerium. A third polymer with different linker, ethylenediamine (EDA) instead of PDA, was synthesized using cerium initiated graft polymerization to inspect the impact of the linker on the removal efficiency. The synthesized polymers were characterized using different char...
