Chemical Reaction Engineering II

By Prof. Ganesh Viswanathan   |   IIT Bombay
Learners enrolled: 50
ABOUT THE COURSE : Multiphase catalytic and non-catalytic reactors are ubiquitously found in chemical, biochemical and petrochemical industries for manufacturing variety of useful products. Effective design of such reactors for improved productivity requires detailed understanding of the underlying principles that govern their functioning. This second level course on chemical reaction engineering will extensively cover design of fluid-solid catalytic and non- catalytic reactors. Moreover, residence time distribution is an important aspect that is often used for various fault- diagnosis purposes. This course also covers various aspects of RTD and its applicability in designing non-ideal reactors. The material covered in this course will build on the basic topics of the first level chemical reaction engineering course.

INTENDED AUDIENCE : Chemical Engineering, Energy Engineering, Environmental Engineering, Petrochemical engineering, Biotechnology

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 
30 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Bombay.It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
