How We Teach: Kinetics and Reactor Design
Abstract
The Survey Committee of AIChE's Education Division surveys departments in the US and Canada each fall. Kinetics and reactor design or chemical reaction engineering was the topic for Fall 2020. This paper presents results from 87 different courses representing 80 distinct institutions as well as discussion from the survey session at the AIChE Annual Meeting. Results are compared with previous surveys in 2010 and earlier.
Almost all departments still require only one three-credit-hour course in kinetics and reactor design. Fogler's textbooks are still the most popular. Over 80% of courses cover topics through steady-state reactors in depth. Over 60% of courses also cover unsteady non-isothermal reactors and reaction hazards but with less depth. Over half of the courses responded that more than 50% of the homework assignments use a computer, which is a substantial increase from the survey in 2010. Exams and individual homework assignments are still the most popular assessments, but team homework and team projects are increasing. The course is used to assess the achievement of ABET Student Outcomes 1 and 2 in half of the courses. The majority of departments have laboratory exercises devoted to kinetics and reactor design in a required course, with experiments within the kinetics and reactor design courses themselves in over a quarter of departments.
Survey Distribution and Respondents
Each year the AIChE Education Division (EdDiv) Survey Committee surveys departments in the US and Canada over some portion of the undergraduate curriculum. The survey for 2020 presented in Appendix A was over kinetics and reactor design, also called chemical reaction engineering. The survey was created in Qualtrics and offered over the web and as a paper survey. It was distributed to the EdDiv Chairs email list, the EdDiv newsletter, EdDiv social media, EdDiv virtual community of practice on reactor design courses, the American Society for Engineering Education Chemical Engineering Division newsletter, and individual emails to chairs of Canadian chemical engineering departments in September and October 2020. The survey link was also posted during sessions at the AIChE Annual Meeting.
The 80 responding institutions are listed in Appendix B; thank you for your contributions. Three institutions have replies from two different professors who both teach the course. Not all questions were answered by all respondents. Comparing the survey respondents to the US and Canadian institutions overall is more difficult this year as ASEE has changed the data reported in their Engineering by the Numbers [1]. Graduating class sizes for the top 50 US chemical engineering programs by size are presented, and demographics are given only by all 160 US programs in aggregate. Twenty-two of the top 50 US programs by graduating class size responded to the survey. Top 50 by class size US institutions are nearly equally represented in the US (50 of 160, 31%) and our survey respondents (22 of 80, 28%). Figure 1 compares the graduating class size for our respondents in the top 50 to those top 50 US institutions by class size. Our respondents in this group do have larger class sizes by 8 students on average.

Figure 1. Graduating class sizes of the top 50 chemical engineering programs in the US by class size compared with survey-responding institutions within the top 50 by size. Note that the range is from 80 to 260 students.
Of the 80 distinct institutions, 92.5% (74) use semesters and 7.5% use trimesters. Institutions in the United States were 75 of the 80 responding institutions (93.5%), and 5 were Canadian, which is an increase from the 2019 EdDiv survey on the first year experience [2].
The vast majority of the 80 distinct departments required one three-credit-hour course, which has changed little over the surveys from 1974, 1984, 1991, and 2010 [3]. One course is required at 76 institutions, and four institutions require two courses. Of the four institutions requiring two courses, two are Canadian and one uses trimesters. For credit hours, 59 institutions (74%) have a 3-credit-hour course, and 13 (16%) have a 4-credit-hour course. Only two of the 4-credit-hour courses are offered at institutions on the quarter system. The range was from 0.5 to 36 credit hours, which may be credit units or other accounting systems.
Although the survey did not include the timing of the kinetics and reactor design course in the curriculum, the majority of the attendees at the survey discussion session at the 2020 AIChE Annual Meeting plan the course for the second semester of the junior year.
Fogler's Elements [4] and Essentials of Chemical Reaction Engineering [5] textbooks are still the most popular, used by 60% of the 85 reporting courses, as shown in Figure 2. Fogler's textbooks were also the most commonly used in the 1991 and 2010 surveys [6]. A sixth edition of the Folger Elements textbook was released in Fall 2020 but was not captured in this survey. The "Other" category includes books by Hill, Froment, Hayes, and Davis as well as others not further described. The websites used most often in 63 responding courses are the textbook website and the course's learning management system (Figure 3). Other resources not specifically listed in the figure include Chemical Safety Board videos [7], SACHE materials [8], CACHE learning modules [9], Concept Warehouse [10], and Wolfram Alpha.

We asked respondents about the topics covered in their courses, using the chapter titles from Fogler's Elements book and categories of "not covered', "some", and "in depth". In the 84 courses reporting, early topics in Fogler's text, through isothermal reactors, are nearly universally covered in depth (Figure 4). Multiple reactions are covered at least some at all reporting institutions.
