| المستخلص: | The catalytic conversion of methanol to hydrocarbons of gasoline range has been studied over H-Beta, CuO/H-Beta, and HZSM-5. The catalysts were characterized by X-ray diffraction and TGA technique. The performances of the catalysts were evaluated by conducting experiments in a Microcatetest unit (MCB 890) fixed bed reactor made of stainless steel. Experiments were carried out at 10 bar and different reaction temperatures (300, 350, and 400 ◦C) at constant flow rate of methanol (0.2 ml/min) and constant pressure (10bar). GC technique was used to quantify the reaction products. The major products were methyl benzene, octane, 1,2,3- trimethyl benzene, 1,2,4,5- tetramethyl benzene, pentamethyl benzene, and hexamethyl benzene. The results obtained after catalytic cracking of methanol were also validated by using several kinetic models proposed worldwide.The kinetic parameters for various models were calculated by solving the equation of mass conservation inthe reactor for the lumps of the kinetic models.The Kinetic Model of Methanol to Gasoline (MTG) Reactions over H-Beta,H-ZSM5 and CuO/H-Beta Catalysts is second order (since reaction is carried out different temperature and constant partial pressure) using Arrhenius equation by using Polymath and Excel software. |
