Contained Copper Adsorbent Preparation And Kerosene Sweetening

In this paper,the novel adsorbents are produced and their application on removal of sulfur-containing organic compounds is discussed.1,Three unique kinds of Cu-containing absorbents based on different carriers including 13X molecular sieve,activated alumina,and activated carbon,are synthesized by immersion method in the Cu₂Cl₂-NH₃·H₂O medium and all do exhibit good removal effect on coal oil.It has been demonstrated that 13X molecular sieve and activated carbon display better removal result under proper reaction condition(Cu₂Cl₂/NH3·H₂O=60g/L, Immersion Time=2 hour,Absorption Time=2 hour).2,The Cu-containing absorbents based on different carriers including activated alumina(home-made),and activated carbon,are synthesized by electroless copper planting,and all do exhibit perfect removal effect on coal oil.3,Changing different preparation conditions,comparison impregnated adsorbents with electroless planting adsorbents,electroless planting-copper-containing alumina has a good quality,its best preparation condition is:Al salts:sucrose=2:1,the concentration of every componcnt of the planting solution is 0.8g,formaldehyde=3.15mL.4,By comparing with their R²,thioalcohol adsorbing on Cu¹-containing alumina absorbent is more appropriate to use second-order kinetic model to demonstrate the absorption process.Apparent activation energy is calculated by Arrhenius equation, Ea=-55.42KJ/mol,adsorption processes easily,is mainly physical process.5,Studies of fixed bed fluidizing adsorption,electroless planting-copper-containing alumina is of excellent characerization of adsorption,and is very important in industry.6,The method of decontaminating the bed by carbinol is feasible.
