Attached are the experiment summary and the guideline for the section.

Let me know if you have any more questions

I have attached some pictures of the apparatuses and an experimental approach that can help you with the methods section.

– Make sure that the CO2 sensor is set on the 0-100,000 ppm range

– Calibrate for total gas flow and CO2 concentration (in bypass mode)

– Regenerate zeolite

– To save time, temperature will be constant throughout the day

– Setting up logger lite

– The CO2 and N2 valves will then be adjusted to the desired concentration and flow rate in bypass mode keeping in mind that the maximum CO2 concentration sensor reading is ~9.6%

– Once everything stabilizes, the flow will be directed towards the column, starting the run and starting recording.

– Record the data until it reaches a steady value, approximately equaling the inlet concentration initially set.

– Store the data and end the test

– Repeat same steps at different concentrations with the same temperature to get equilibrium isotherm

– Shutting down, we will vacate the CO2 via the above procedure

– Slowly close the CO2 and then the N2 valves

We did 3 concentrations and 3 temperatures

1st day: 80C [2% (490 N2 – 10 CO2) – 4% (480 N2 – 20 CO2) – 8% (460 N2 – 40 CO2 ) mL/min

2nd 90C and 3rd day 100C with the same concentration

For the safety section

btw, those are some main points for the safety section

• delicate equipment
• high voltages and high pressure
• CO2 sensor sensitive
• high pressure temperatures
• fragile quartz glass
• don touch regulators
• don open the oven
• don touch the quartz tube

And for materials you can find a lot of information on zeolite 13x from the experiment summary
