Third Assignment: Advanced Chemical Reaction Engineering

According to Second Assignment (http://tekim.undip.ac.id/staf/istadi/2014/03/second-assignment-advanced-chemical-reaction-engineering/ ), please solve the following question for Chemical Reactor Design:

  1. Based on the reaction rate law resulted from the second assignment, with assumption of neglecting pressure drop, please calculate Catalyst Weight (W) necessary to achieve 80% conversion in a CSTR Reactor
  2. Based on the reaction rate law resulted from the second assignment, with assumption of neglecting pressure drop, please calculate Catalyst Weight (W) necessary to achieve 80% conversion in a Plug-Flow Reactor
  3. If pressure drop is taken into account, and the 1/8-in catalyst pellet are packed in 1.5 in schedule 80 pipes 35 ft long, what catalyst weight (W) is necessary to achieve 80 % conversion? Void fraction is 40% and the density of catalyst is 2.6 g/cm3

The solution of the problem should be typed in a MS Word or PDF file. The solution file (PDF and Polymath files) should be collected by email attachment to the following email: istadi@che.undip.ac.id before 3 May 2014. Please be noted that subject of email should contain: your name, your NIM, and “Assignment #3 Advanced Chemical Reaction Engineering” or “Tugas ke-3 Teknik Reaksi Kimia Lanjut”.

Kalibrasi Battery MacBook Air

  1. Charge battery sampai indikasi di layar atau icon battery menunjukkan fully charged.
  2. Biarkan battery dalam kondisi fully charged minimal 2 jam (jangan lepas MagSafe Power Adapter). Anda boleh menggunakan MacBook selama battery masih dalam keadaan charging.
  3. Lepaskan colokkan dengan keadaan MacBook masih nyala dan gunakan battery tersebut. Anda boleh menggunakan MacBook pada saat ini.
  4. Biarkan/gunakan MacBook dalam keadaan tersebut sampai MacBook sleep karena kehabisan battery. Jangan lupa untuk menyimpan dokumen yang sedang dikerjakan. Biarkan battery dalam kondisi sleep minimal 5 jam.
  5. Charge sampai full. Battery anda sudah terkalibrasi

Second Assignment: Advanced Chemical Reaction Engineering

This second assignment for Advanced Chemical Reaction Engineering Course of Master Program in Chemical Engineering was derived from Fogler’s Book (Third Edition) Problem 10-9. Hydrogenation of i-octene to form i-octane were obtained using a differential reactor operated at 200 oC. The experimental data are as follow:

Questions:

  1. Develop a reaction rate law appropriate with this reaction (possibility controlling mechanism: (a) if adsorption controlling; (b) if surface reaction controlling; and (c) if desorption controlling
  2. Suggest a mechanism consistent with the above experimental data
  3. Evaluate the reaction rate law model parameters according to the above experimental data. Usage of Polymath software was recommended to solve the fitting.

The solution of the problem should be typed in a MS Word or PDF file. The solution file (PDF and Polymath files) should be collected by email attachment to the following email: istadi@che.undip.ac.id before 12 April 2014. Please be noted that subject of email should contain: your name, your NIM, and “Assignment #2 Advanced Chemical Reaction Engineering” or “Tugas ke-2 Teknik Reaksi Kimia Lanjut”.

Tugas #1 Teknik Reaksi Kimia Lanjut (Advanced Chemical Reaction Engineering)

  • Setiap mahasiswa diharuskan mencari sebuah literatur artikel jurnal (carilah di Sciencedirect – http://www.sciencedirect.com) tentang heterogeneous reaction kinetics yang melibatkan reaksi dengan katalis padat (petunjuk kata kunci: “heterogeneous” AND “chemical reaction kinetics”
  • Buat ringkasan artikel tersebut, meliputi: tujuan, metode, hasil, dan kesimpulan
  • Buat kritikan terhadap artikel jurnal tersebut, meliputi kelemahannya dan apa yang seharusnya dilakukan
  • Tugas #1 ini wajib dikumpulkan tanggal 29 Maret 2014
