Description

Data description: The yield, detailed characterization of LRC, bio-oil, syngas, and bio-char obtained from MP + HZSM-5 + Fe2(SO4)3 and MP + AC + Fe2(SO4)3 are all shown in this dataset. Fig. 1 shows the mineral composition of the HZSM-5 catalyst, as well as the proximate and ultimate analyses of the LRC and AC catalysts. Fig. 2 shows the XRD analysis in the form of the stability of the AC and HZSM-5 catalyst compositions at 550-620℃. Tables 1-2 shows the profile of temperature rise in the ratio of HZSM + Fe2(SO4)3 and AC + Fe2(SO4)3 to LRC, as well as the carbon distribution from the products (liquid, syngas, and bio-char). At MP + 1.0%HZSM-5 + 24.6%Fe2(SO4)3 and MP + 1.0%AC + 24.6%Fe2(SO4)3, the total weight loss equals the accumulations of liquid yield and syngas yield. Eqs. (1-4) was used to measure the total weight loss. Y_liquid=(〖(V.ρ)〗_(tray 1)+〖(V.ρ)〗_(tray 2)+ (〖V.ρ)〗_(tray 3)+ (V.ρ)_(tray end))/(m_(low-rank coal) ) x 100% (1) Y_(bio-char)=m_(bio-char)/m_(low-rank coal) x 100% (2) Y_syngas=100%-Y_liquid-Y_(bio-char) (3) Total weight loss (TWL)=Y_liquid+Y_syngas (4) At MP + 1.0%HZSM-5 + 24.6%Fe2(SO4)3 and MP + 1.0%AC + 24.6Fe2(SO4)3, Tables 3-5 shows the effect of pyrolysis temperature, input power, and reaction time on product yield, as measured by total weight loss, which is the product of liquid and syngas yields. For each MP + 1.0%HZSM + 24.6%Fe2(SO4)3 and MP + 1.0%AC + 24.6Fe2(SO4)3, the total weight loss was determined using Eq. (4) with variables in pyrolysis temperature (570-620°C), input power (0-800 Watt), and reaction time (15-135 minutes). Tables 6 show the GC-MS analysis of relative values of the major pyrolysis components inside the oils, as well as the classification of bio-oil following comparison to standard fuels. The syngas properties at MP + 1.0%HZSM + 24.6%Fe2(SO4)3 and MP + 1.0%AC + 24.6Fe2(SO4)3 are described in Table 7. Fig. 3 describes the physical characteristics of bio-oil: (a) density; (b) viscosity.

Steps to reproduce

• Data from the yield measurement of the product, which begins with the determination of the density of the liquid product and the total weight loss (TWL). Where the liquid yield was the total mass of the liquid divided by the mass of the feed multiplied by 100% (the total mass of the liquid was the mass accumulation of tray-I, tray-II, tray-III, and tray-end); char yield was char mass divided by feed mass multiplied by 100%; syngas yield was 100% subtracted from liquid yield and char yield; and TWL was the liquid yield plus the syngas yield. • Data from the analysis of pyrolysis products, including proximate analysis and micromorphology of char products. Proximate analysis performed through ASTM includes ASTM D3172-D3175 (ash content, moisture, fixed carbon, and volatile matter). Then micromorphology of LRC and char using Scanning Electron Microscope (SEM). Analysis of X-ray diffraction (XRD) on the crystal structure of LRC and char from the effects of HZSM-5 + Fe2(SO4)3 and AC + Fe2(SO4). Fourier transports infrared (FTIR) spectrometer was used to analyze the organic functional groups of tar and liquid fuels. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the components of liquid fuel, tar, and syngas.
