基于微波耦合碳分散镍催化的废塑料制氢
Hydrogen production from plastic waste by microwave-coupled carbon-dispersed nickel catalysis
摘要
Abstract
To achieve high hydrogen production and high hydrogen selectivity in hydrogen production from plastic waste,Ni/C catalysts were synthesized using two methods:a traditional electric furnace and microwave-assisted synthesis.Raman spectroscopy,thermogravimetric analysis,SEM,TEM,XRD and other methods were used to characterize the Ni/C catalyst and the carbon products after dehydrogenation of plastics,the effects of the two catalysts on the dehydrogenation efficiency and product distribution of plastics under microwave irradiation were compared and analyzed,and the reasons for the differences in the activities of Ni/C catalysts synthesized by the two methods were explored.The results show that the microwave-assisted synthesis of Ni/C catalyst has excellent microwave heating and selective cleaving ability of C-H bonds,finally achieving a hydrogen yield of 53.1 mmol/g(g is quali-ty of plastic)and hydrogen selectivity of 87％.The carbon produced after the dehydrogenation of plastics is de-posited on the catalyst's surface and crystallized into high value-added carbon nanotubes.关键词
