Specific course objectivesa. Students will be able to:1. Write reaction rate laws for single elementary reactions and/or stated complex liquidphase reactions2. Express concentrations in terms of conversion for liquid (constant density) systemsusing the given reaction stoichiometry and reactor feed3. Calculate the requested unknown (e.g. volume, space time) using the appropriatespecies balance for the assigned liquid phase steady-state flow reactor (CSTR, PFR)4. Write reaction rate laws for single elementary reactions and/or stated complex gasphase reactions5. Express concentrations in terms of conversion for gas (variable density) systems usingthe given reaction stoichiometry and reactor feed6. Simplify concentration expressions for dilute gas systems using problem-specificappropriate assumptions7. Calculate the requested unknown (e.g. volume, space time) using the appropriatespecies balance for the assigned gas phase steady-state flow reactor (CSTR, PFR)8. Derive the appropriate energy balance for the assigned steady-state flow reactor9. Combine species, energy balances to determine unknown quantity (time, conversion,energy transfer rate, temperature) for steady-state flow reactors10. Model (species, energy balances) the pre-upset (steady-state) condition for a CSTRwith emphasis on process safety (e.g. runaway)11. Model (species, energy balances) the upset (transient) condition for a CSTR and for abatch reactor with emphasis on process safety (e.g. runaway)12. Derive a rate expression based on an elementary mechanism using the Pseudo SteadyState Hypothesis or Langmuir–Hinshelwood algorithm for homogeneous andheterogeneous catalytic systems13. Express concentrations in terms of conversion for both liquid and gas catalytic systemsusing stoichiometry and feed/charge conditions14. Calculate the required unknowns (e.g. volume, time) using the appropriate speciesbalance for assigned catalytic reactor315. Derive species net reaction rates from multiple reaction networks16. Design the required reactor using the energy and species balances in a multiple reactionproblem17. Complete a team-based term project by preparing the basic reactor design using energyand species balances18. Produce a professional, team-based memo with sound presentation of results andquality graphs19. Solve algebraic (linear, quadratic) equations and ODEs (separation of variables)analytically (by hand)20. Solve term project multiple-equation (algebraic, ODEs) problems usingcomputer-based numerical softwareb. This course explicitly addresses ABET student outcomes 1, 2, 3, 4:1. An ability to identify, formulate, and solve complex engineering problems by applyingprinciples of engineering, science, and mathematics2. An ability to apply engineering design to produce solutions that meet specified needswith consideration of public health, safety, and welfare, as well as global, cultural,social, environmental, and economic factors3. An ability to communicate effectively with a range of audiences4. An ability to recognize ethical and professional responsibilities in engineeringsituations and make informed judgments, which must consider the impact ofengineering solutions in global, economic, environmental, and societal contexts7. GradingThe final grade on a 1000 point basis as follows:Homework (team work) 100 pts (10%)Team project (team work) 100 pts (10%)1st term exam (individual) 250 pts (25%)2nd term exam (individual) 250 pts (25%)Final exam (individual) 300  " (30%)Letter grades will be awarded for the following totals:A 850 and aboveB+ 800-849   "B 750-799   "C+ 700-749   "C 650-699   "D                       550-649   "F   less than 550   "8. Policies on assignments/exams and classroom policyHomework: Homework assignments will be collected and graded. Homeworkassignments are the responsibility of the students. You are strongly advised to work4on the homework problems because you will NOT learn this material unless you getinto the materials “Hands-on”. All solutions will be posted on the course Canvassite. All homework assignments, however, must be submitted before the solutionsare reviewed in class.Group activities policy:Everyone within a Term Project group must contribute effort equally.  A Peer & SelfEvaluation will be done after the group projects are submitted.  Each student will beasked at the end of the semester to confidentially rate his/her performance/effort as wellas that of all his/her group-mates. The completed evaluation form has to be attached toan e-mail to the instructor.  Evaluation forms are due on Dec 13th 2021.  Submission ofthe form after Dec. 13th 2021 and before the final exam will result to the late submittergetting 75% of the credit that he/she would had received if the form was submittedtimely.  Submission of the form at the final exam will lead to a further 25% reduction ofthe credit.  No student will be allowed to take the final exam without prior submission ofthe self & peer evaluation form.Exam policy: All exams are open textbook/ instructor lecture notes.  Gradedhomework problems cannot be used during exams.  Additional personal notes on thecourse (or solutions to additional problems), copies of class notes, as well as copies of theinstructor’s solutions to homework problems are also not allowed to be used duringexams. Graded exams will be returned in about a week after they are taken.1) Cheating on exams will not be tolerated.2) Your textbook, class notes and calculator are the only things allowed3) Cellphone MUST be OFF except that you use your cellphone camera for your exam!4) It is your own responsibility to make sure you submit all the pages of your exam!!!!Policy on exams (other than final): A student must have a compelling reason to missan exam.  Documentation of the reason (e.g., doctor’s note) is needed for the instructor toconsider giving a make-up exam.  A student who cannot make it to an exam needs toeither e-mail or call and leave a voice message for the instructor before the exam is held.A single (comprehensive) make-up exam will be given on the reading day (Dec. 13th2021) for those who have missed an exam for documented/ legitimate reasons.Policy on final exam: The final exam will be based on the entire course material.Students missing the final exam without a documented serious excuse fail the course.Students missing the final exam with a documented serious reason get an Incomplete.The Incomplete will be removed after students take the final exam in Spring 2022 (gradeto count towards 30% of the composite).  If the course is not offered in Spring 2022, aspecial make-up final will be scheduled during the Spring 2022 finals week.Disputing a grade on tests/assignments: If a student has questions about the gradehe/she has received on an exam, homework, or group activity he/she must talk to theinstructor (or the teaching assistant where appropriate) no later than a week after thegraded activity has been returned to students.  No grade change will be made afterthe one week period.5Term Project: Work in groups (you form). A Peer & Self Evaluation will be done at theconclusion of the project that will impact your grade; more details later. Agroup project presentation is required at the end of the semester. Everyoneshould present part of their project. A group project report is recommended, butnot mandatory.Canvas Site: http://canvas.njit.edu --- Please check this site and your email often (at least once a day).Practice problems will be posted, as well as HW and test solutions, group projects, somein-class work, and useful memos.Policy on Integrity: Professional behavior is expected at all times in this course.● On-time arrival for the start of class is expected.● Cheating on exams will not be tolerated.  If calculations are required, only calculators arepermitted.  All cell phones must be away during exams.● All homework assignments must be submitted before the solutions are reviewed in class.● Everyone within a Term Project group must contribute effort equally.  A Peer & SelfEvaluation will be done after the group projects are submitted.● If you use Polymath, you must obey the license terms – no commercial use; for education useonly.9: Exam preparation1. Understand lecture materials and basic concepts2. Do all homework problems3. Do example problems covered in lecturesGroup Project: Details for the group project and requirementswill be sent in a separate file!610: Tentative Schedule7
