Dataset for "Zeolite Minilith: A Unique Structured Catalyst for the Methanol to Gasoline Process"

Data collection method:

[1] The ZSM-5 miniliths were characterised using nitrogen sorption, SEM, TGA, EDX and XRD. [2] The conversion of methanol to gasoline was carried at 370 C, 3 bar and WHSV up to 1174 h^-1 over ZSM-5 miniliths and the reaction products were sampled through an online gas chromatography (Shimadzu GC 2010) equipped with a flame ionisation detector and an Equity-1 fused silica capillary column (90m × 0.53mm × 3.0µm). Raw data containing retention times of various products and their corresponding areas and heights were obtained. [3] Stability tests were conducted over zeolite miniliths and zeolite powders of equal ZSM-5 weight up to time-on-stream of 140 h, flowrate of 54 mL/min and pressure of 3 bar and temperature of 370 C. Raw data containing retention times of various products and their corresponding areas and heights were obtained.

Data processing and preparation activities:

The raw data i.e. concentration (areas, height) collected from the GC-FID was then converted to processed data i.e. concentration (ppm) for the measured product species using a MATLAB code written by Dr Nikolay Cherkasov (University of Warwick). Data were obtained for methanol, dimethyl ether, C1-C10 aliphatics and C6-C10 aromatics.

Technical details and requirements:

Data were obtained during catalytic tests as .gcd files. They were converted to .txt using the GC-FID. Notepad was used to read raw data .txt files. .txt files were processed using a MATLAB code to .xlsx files. Microsoft Excel 2016 was used to analyse the GC-FID data, TGA, nitrogen sorption (ASAP2020 and 3Flex). ImageJ for SEM data. Veusz 2.0.1 for data visualisation of XRD. Microsoft Excel 2016 was used for data visualisation of catalytic tests
