Biomass is abundant and sustainable with CO2 neutral and less dependent on climate. Its potential application could be obtained from biomass by the pyrolysis process. Meranti sawdust from industrial waste is widely available and can be used as feedstock to produce bio-oil through the pyrolysis process. The utilization of nitrogen as a sweep gas in pyrolysis requires additional components and incurs additional costs in production. The research aims to investigate non-sweep gas pyrolysis with vapor heater using Meranti (Shorea pinanga) as feedstock. The Proportional Integral Differential (PID) was installed to control the reactor and reaction zone temperature. Liquid yield increased due to the increased surface temperature at the reaction zone. The maximum liquid yield was obtained of 39 wt% at the reaction zone temperature 150 ⁰C. The liquid yield composition consists of a high boiling substance with a higher heating value and an increase of vapor temperature. Meanwhile, the liquid product without a heater in the reaction zone relatively contained the compound with a lower boiling point, and it had a lower heating value.
