Abstract- The increasing global demand for cleaner energy sources has made the attainable and innovative conversion of biomass residue from empty palm fruit bundles into compressed fuel a reality. Oil palm-based wastes have become a significant source of renewable fuels and chemicals with high liquid and lower gas yields. In the quest to transition to a renewable energy future, lignocellulosic biomass including oil palm-based biomass is currently the cheapest and least harmful material that offers the prospect of producing clean energy that effectively rivals fossil fuels in terms of efficiency and sustainability fuels can compete. Although the cost of energy production from lignocellulosic biomass cannot currently compete with fossil fuel sources due to the lengthy processing and utilization process, the potential exists to effectively compete with fossil fuels. The fact that biomass is inexhaustible and renewable, low in sulfur and nitrogen, environmentally friendly, and sustainable is a major advantage of its use for energy production. Furthermore, unlike fossil fuels, which contribute to the increase in greenhouse gas emissions (GHGs), biomass energy has no impact on the natural carbon-CO2 cycle.

In the quest to transition to a renewable energy future, lignocellulosic biomass including oil palm-based biomass is currently the cheapest and least harmful material that offers the prospect of producing clean energy that effectively rivals fossil fuels in terms of efficiency and sustainability fuels can compete. Although the cost of energy production from lignocellulosic biomass cannot currently compete with fossil fuel sources due to the lengthy processing and utilization process, the potential exists to effectively compete with fossil fuels. The fact that biomass is inexhaustible and renewable, low in sulfur and nitrogen, environmentally friendly, and sustainable is a major advantage of its use for energy production. Furthermore, unlike fossil fuels, which contribute to the increase in greenhouse gas emissions (GHGs), biomass energy has no impact on the natural carbon-CO2 cycle. Thermochemical and biochemical routes are used to obtain energy from biomass, with thermochemical routes being more convenient and efficient. This article reviews studies on the pyrolysis of empty palm fruit bunch biomass for bio-oil production, to reduce environmental impact and dependence on fossil fuels. It provides a detailed description of the reactors and pyrolysis technology.
