Abstract

This study aims to determine bio-oil production from a mixture of low rank coal (C) and microalgae Chlorella vulgaris (A) with 1 wt% HZSM-5 catalyst using microwave pyrolysis. In a batch reactor, pyrolysis was conducted at 500 °C under vacuum (−10 mmH₂O). Operation variables included C/A ratio, pyrolysis time, and input power to obtain optimal bio-oil production. Bio-oil was analyzed by characterizing their physical properties, including its density and viscosity using GC–MS and FTIR. Optimal condition resulting in bio-oil yield of 33.8 wt% was found with C/A ratio of 4:6 and reaction time of 75 min. The outcomes of the present work can accelerate the development of biofuel production from microalgae to reduce carbon footprints from the massive use of conventional fuels.
