Description

The main processes of bio-oil production from low-rank coal (LRC) through microwave pyrolysis were microwave assisted catalytic + receptor pyrolysis (MACP). The main equipment used consists of a microwave, furnace, and distillation column with bubble-cap tray. The column was made from glass pipe equipped with connectors, condensers, and trays. The furnace used was made of stainless steel, the input power was 1200 W, the voltage was 220 V, and the maximum temperature was 750℃. The microwave used has an output power of 800 W, an input power of 1250 W, a voltage of 220 V, a magnetron frequency of 2.45 GHz, and an external dimension of 485 x 370 x 292.2 mm. The LRC pyrolysis process begins with showing the effect of temperature on the conversion of LRC into liquid fuel, syngas, and char at MACP. The initial conditions for the LRC pyrolysis research process were sub-bituminous; particle size 4 mesh; LRC mass 150 g; ratio of Fe2(SO4)3 to LRC 1:5; catalyst type HZSM-5 and activated carbon (AC); catalyst to LRC ratio 1:100, input power 450 W; time 60 minutes; and a process pressure of -10 mmH2O. The variables used were conventional pyrolysis (CP) + catalyst + receptor and MP + catalyst + receptor; reaction temperature is 570-650℃ (increase 10℃); input power was 0, 150, 225, 300, 325, 450, 525, 600, 700, and 800 W; time was 15-135 minutes (increase 15 minutes); LRC particle sizes are 4, 16, 40, 80, 100, 150, and 200 mesh. The magnitude of the pyrolysis product was the measurement of the yield of the product, which begins with determining the density of the liquid product and the total weight loss (TWL). The liquid yield was the total mass of the liquid divided by the mass of the feed times 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 is 100% subtracted from liquid yield and char yield; and TWL was the liquid yield plus the syngas yield. Several analyzes 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. Potential data can be used to convert LRC into liquid fuel and syngas through the MACP method.
