In this paper, the magnetically stabilized bed reactor FCC light gasoline etherification process to develop a core-shell magnetic resin . Nanoscale Fe3O4 particles as the core, by After oleic surface modification , the outer parcel dense polystyrene layer , and the use of concentrated H2SO4 as the functional groups of the sulfonating reagent connection -SO3H , and thus , the sulfonation process done improved to enhance the resin magnetic . The the chemical coprecipitation prepared Fe3O4 particles , vibrating sample magnetometer particle size of Fe3O4 nanoparticles , magnetic properties were characterized using transmission electron microscopy , product particle size 10 - 20nm, than the saturation magnetization up to 81.09 emu / g, with superparamagnetic . By the Modification of oleic acid surface so that it changes from hydrophilic to lipophilic . Fe3O4 / oleic nuclear material , the use of the suspension polymerization magnetic polymer microspheres , styrene (St) as monomer , with water as the reaction medium , azobisisobutyronitrile (AIBN) as initiator , polyvinylalcohol (PVA) as a dispersing agent , and by the sulfonation of concentrated H2SO4 , obtained saturation magnetization of 3.13emu / g and exchange capacity of 2.46 mmol / g of the magnetic cation exchange resin . Finally introduction of sodium styrene sulfonate (NaSS) as the third monomer , using a soap-free emulsion prepared directly Na type magnetic resin 31.41 emu / g , saturation magnetization , the exchange capacity of 0.79 mmol / g .
