Preparation Of Functionalized Nanocomposites For Improving Diesel Fuel’s Combustion And Gathering

With the acceleration of the industrialization process,the global demand for fossil energy is increasing,and the energy crisis and environmental pollution are becoming more and more serious all over the world.As one of the main products of petrochemical industry,diesel is a kind of mass liquid energy fuel that is widely used and has a large burning power value.However,there are frequent leakage accidents during the use of diesel fuel,and the combustion efficiency is low.It is easy to produce environmental pollution caused by carbon deposition,harmful gases and particulate pollutants,resulting in great energy waste and environmental pollution.Therefore,energy conservation,emission reduction and environmental protection have always been a worldwide economic,social and environmental themes.Nano materials,with the properties of its unique microstructure,high specific surface area and friendly environment,has a great advantage in contrast to other physical,chemical,and biological materials in terms of improving energy efficiency and controlling environmental pollution.In recent years,scientists have developed some nano materials for improving energy efficiency and environmental protection.But the actual effect is not ideal with the long preparation time,complex process and high cost.However,the technology of high energy electron beam irradiation and modify of hydrophobic,have the advantages of mass production with simple and highly effective.Therefore,the technology of highly energy electron beam irradiation and modify of hydrophobic,has attracted more attention in the preparation of nano materials.We fabricated different functional composite materials in this paper,and applied them to improve the efficiency of diesel combustion in boilers,recovery of diesel fuel in the water and soil,based on porous nano materials which were modified with HEEB irradiation and inorganic modification.The main research contents of this paper are as follows:1.Choose high specific surface and high surface activity of attapulgite(ATP)as raw materials,using HEEB irradiation,through the thermal motion,charge and physical impact effect scatter ATP rods into the micro/nano network structure to improve the dispersion of attapulgite and increase its potential energy surface,furthermore,preparing a novel nanocomposites HA30-APTES-ASO(HAAA)by further dealcoholization modification with amino siliconoil(ASO)and aminopropyltriethoxysilane(APTES).As the results of the study proved,HAAA possessed a micro/nano network structure and could adsorb diesel fuel(DF)molecules on the surface of HAAA nanorods,which enhanced the contact of DF with oxygen and thus effectively enhanced the combustion efficiency of DF.At the same time,HAAA can increase the fly ash particle size of combustion,reduce the total amount of fly ash,and decrease the emission of gas,which potentially favored the reduction of PM2.5.After combustion,the residue,carbon nanoparticles wrapping on the surface of HAAA nanorods,were obtained and displayed a high capacity of removing cadmium ions(Cd2+)from aqueous solution.2.The nano-sponge(NSP)of a novel hydrophilic nanocomposite material can be synthesized easily and quickly by using the silanation of ASO and APTES.The study shows that the hydrophobic modification of ASO and APTES increases the porosity of the original sponge and the contact area with diesel fuel,thus absorbing more diesel fuel.NSP could restrain the diesel fuel leaching in the sand and migration effect longitudinally,effectively gathering diesel fuel in soil and water,reducing the concentration of diesel in the environment,decreasing diesel oil migration,proliferation and transpiration,reducing the pollution of diesel on the toxicity of man and animal and plant growth in the environment,which were proved by our research.
