Unfortunately, I am unable to access attachments or perform mathematical modeling. However, I can provide general information and guidance based on the given problem description.

To analyze the relationship between ethanol conversion, selectivity of C4 olefins, and temperature for each catalyst combination in Attachment 1, you can plot the data and observe the trends. Plotting ethanol conversion and selectivity of C4 olefins against temperature for each catalyst combination will allow you to visualize the relationship.

For the given catalyst combination in Attachment 2 at 350 degrees, you can analyze the test results at different time points to observe any changes in ethanol conversion and selectivity of C4 olefins over time. Plotting the data at different time points will provide insights into the catalyst's stability and performance over the reaction duration.

To explore the impact of different catalyst combinations and temperatures on ethanol conversion and selectivity of C4 olefins, you can compare the data from different catalyst combinations at different temperatures. By analyzing the trends, you can identify which catalyst combinations and temperatures yield higher conversion rates and selectivities.

To maximize the C4 olefin yield under the same experimental conditions, you need to select the catalyst combination and temperature that yield the highest C4 olefin selectivity and conversion rate. By analyzing the data, you can identify the optimal catalyst combination and temperature for maximizing C4 olefin yield.

If you are allowed to conduct 5 additional experiments, you should design them based on the factors that significantly affect ethanol conversion and C4 olefin selectivity. You can vary the catalyst combination and temperature to explore their effects on the desired outcomes. It is important to choose different combinations and temperatures that have not been previously tested to gather more comprehensive data
