Experimental dataset of microwave-assisted pyrolysis of low rank coal using HZSM-5 and activated carbon catalyst to produce liquid fuel

Description

The main equipment used consisted of a reactor made of Pyrex glass, a microwave oven, and a distillation column with a bubble-cap tray. Initially, 150 g of coal of a certain particle size was prepared: promoter and catalyst with a certain ratio. Operating conditions at atmospheric pressure with operating variables as follows: reaction temperature between 843 - 923 K (increase 10 K); microwave input power is 0 - 800 W (increase by 75 W); pyrolysis time 900 - 8,100 s (increase every 900 s). The coal particle sizes are 4.76; 1.19; 0.42; 0.18; 0.15; 0.11; and 0.07 mm. The liquid fuel obtained is weighed and characterization is carried out.

Steps to reproduce

- The yield of liquid product is determined from the total mass of the liquid obtained divided by the mass of the feed multiplied by 100%. Meanwhile, the char yield is the mass of char divided by the mass of the feed multiplied by 100%. - Proximate analysis performed using the ASTM D3172-D3175 method. - SEM is used to obtain the micromorphology of raw coal and char. - XRD analysis (PANanalytical’s MiniPal 4) on the crystal structure of coal and char. - FTIR spectrometer (Shimadzu, IRPrestige-21) was used to analyze the organic functional groups of liquid fuel. - GC-MS was used to analyze the components of liquid fuel and gas.
