Abstract—Continuous pyrolysis process to produce bio-oil from three residual plants, conducted at a temperature range of 450-600°C, were to study the quality of bio-oil extracted from different residual plants were, 1) Oil palm empty fruit bunch [Rpt-1], 2) Water hyacinth [Rpt-2], and 3) Manila grass [Rpt-3]. The preliminary analyses of three residual plants found that the yield of bio-oil was averaging of medium range standard, and The proximate analysis of three residual plants extracted from three residual plants had good qualities because of low moisture content and high fixed carbon and high volatile matter. The element contents of three residual plants found that high carbon content. The analysis of bio-oil can found the heating values averages of bio-oil from [Rpt-2] and [Rpt-3] were difference from bio-oil obtained from [Rpt-1], both [Rpt-2] and [Rpt-3] held that there was in the Heating Value of high-level or better standards, especially bio-oil obtained from [Rpt-2] have a highest value averaging of 30.5 MJ/Kg. The amount of carbon in the bio-oil obtained from [Rpt-1], [Rpt-2] and [Rpt-3] were 55.91, 55.57, and 55.03 wt.%., respectively., carbon was relatively high in three residual plants. Hence; In this research are concerns the feeding rate, velocity of screw feeders, the control nitrogen flow, the temperatures in reactor and reactor operate for produce the hi quality of bio-oil with three residual plants.
