5 2012/12/04 2. The reactor -catalyst Some characteristics of D005 Exchange capacity, mmol/g[H + ]≥5.2 Water content, %50-58 Bulk density, g/ml0.75-0.85 Wet true density, g/m1.18-1.28 Particle diameter, mm0.315-1.25 Pore diameter, nm8-45 Surface area, m 2 /g40-50 Porosity, ml/g0.35-0.40 Maximum operation temperature, ℃ 120 The maximum operation temperature is 120 ℃ The catalyst (D005) is special for MTBE C5+Methanol: D005II (A-35) C6+Enthanol: A-15 (D005) The maximum operation temperature is 120 ℃ The catalyst (D005) is special for MTBE C5+Methanol: D005II (A-35) C6+Enthanol: A-15 (D005)

6 2012/12/04 The reactor model Fixed-bed reactor swelling

7 2012/12/04 The reactor model Expanded reactor a)Mathematical model b)The velocity of flow fluidization velocity, mm/s4.3 The first reactor Volume flow rate, m 3 /h58.53 (19.28×3.2) Diameter, m2.5 velocity, mm/s3.3 The second reacor Volume flow rate, m 3 /h25.89 Diameter, m1.7 velocity, mm/s3.2

8 2012/12/04 The influence factors Conversion (C5, C6) >90%? Outlet temperature The circulation ratio Diameter and Da Length Inlet temperature The ratio of methanol to isomers Who is fixed a)Create a function about all the influence factors, then seek for the optimal value based on the constrain conditions. b)Consider the factors individually, or several factors a)Create a function about all the influence factors, then seek for the optimal value based on the constrain conditions. b)Consider the factors individually, or several factors

9 The axial diffusion coefficient Applicable conditions: Reynolds number for the particle Re p :10 -3 -10 3 Bed porosities:0.4-0.8 The bed porosity is 0.35.
