Both datasets presented can be unzipped for access to data presented in the paper "ZSM-5 Minilith: A Unique Structured Catalyst for the Methanol to Gasoline Process". Both datasets are grouped into 5 folders: 1. Catalytic tests 2. Characterisation (XRD, N2 sorption (with ASAP 2020 equipment and repeats with 3Flex equipment), EDX, SEM and TGA) 3. Stability tests 4. Data Analysis Workbook (showing calculations for minilith and powder studies of equal ZSM-5 weight) 5. Data_6mg_ZSM-5_370C_3bar 6. Code 1. Catalytic tests provides three subfolders (Raw and processed data over bentonite, Raw and processed data over ZSM-5 miniliths, Raw and processed data over ZSM-5 powder) Each folder has a set of .gcd files (raw data obtained from the GC-FID), .txt files (converted raw GC-FID files to raw ASCII data) and overall-processed-data-(converted raw ASCII data to processed data) The processed data is further used in the data analysis workbook. It is important to note that the format for the .gcd files (i.e. 20180308_01_001) gives the yearmonthdate_ID1_ID2.gcd of the file. This matches the .txtfiles given as batch_ID2.txt 2. Characterisation data was obtained separately using different pieces of equipment: A. For EDX - Data was obtained over three separate surfaces of the minilith structure (given for exampel as Sample1_SOl1, Sample1_SOl2 and Sample 1_SOl3) - see full processed data in Sample identification and Si_Al ratios.xlsx. B. N2 sorption (ASAP2020): Data was obtained over an ASAP 2020 equipment and the raw data was re-processed using a 3Flex software to obtain Rouquerol BET. The sample code follows directly from the paper C. N2 sorption (repeats with 3Flex): Selected miniliths (Sample Code A2, B and B2) were repeated with a 3Flex machine. Sample Code A2, B and B2 were given as TOYIN_C, TOYIN_B and TOYIN_A respectively. D. SEM images were obtained as indicated in the paper. Sample code follows directly from the paper for both horizontal (HCS) and vertical cross-section (VCS) E. TGA data for bentonite and ZSM-5 (25) powder F. Powder XRD was obtained as indicated in the paper. Text files (sample indentification) for miniliths and powder are given in their respective folders. 3. Stability tests provides two sub-folders: Raw-data-stability and Processed-data-stability. The former gives .7zip files of stability tests done on Sample C and Zeolite/bentonite powder of equal ZSM-5 weight. The latter gives the processed data (after raw ASCII data has been converted to processed data). The processed data is further used for analysis in the Data analysis workbook 4. The data analysis workbook shows calculations and formulae used for yields, selectivities, product distribution (mass fractions) for all catalytic tests presented in the research article. The data analysis workbook contains 5 worksheets (Catalytic Test_Minilith_Powder, Minilith Stability, Particle Stability). Catalytic Test_Minilith_Powder contains data on Minilith (Sample C), bentonite, Zeolite/powder mixtures, Minilith stability gives stability tests over minilith (Sample C) and particle stability gives stability test over ZSM-5/bentonite powder. The stability tests over ZSM-5/bentonite powder and minilith were of equal ZSM-5 weight. 5. Data_6mg_ZSM-5_370C_3bar contains one Excel workbook containing Sheet 5 and Catalytic Test_particle_6mg. Sheet 5 contains experimental protocol for Catalytic Test_particle_6mg and Catalytic Test_particle_6mg are the tests conducted over 6 mg of ZSM-5 at 370 C and 3 bar 6. The folder "Code" contains two M-files which must be kept in the same folder as the raw experimental data to run. The pathway to this folder must be described in the first line (Directory) of the M-file "gc_process_MTH_detailed.m". Only gc_process_MTH_detailed.m requires execution.
