Abstract—The analyses of the physical and chemical properties of bio-oil by pyrolysis, which takes place at temperatures in the range of 450-600°C, were to compare the quality of bio-oil extracted from different weeds that is, 1) Manila grass [Zoysia Matrella (L.) Merr] (MG) and 2) Water hyacinth [Eichhornia crassipes (Mart.) Solms] (WH). The preliminary analyses of biomass by proximate analysis. The results showed that biomass extracted from both weeds had good qualities because of low moisture content and high fixed carbon. MG found carbon content of 30.77%. While WH was 29.70%. The analysis of bio-oil can found the heating values of bio-oil from MG were difference from bio-oil obtained from WH, both held that there was in the Heating Value of high-level or better standards, especially bio-oil obtained from the MG have a heating value of about 32 MJ/Kg (at 500 °C). The content of sulfur quantity are found that bio-oil from the MG have lowest a sulfur quantity 0.26 wt.% at 400 oC; similarly; bio-oil from the WH have lowest a sulfur quantity 0.27 wt.% at 400 oC. The amount of carbon in the bio-oil obtained from MG and bio-oil obtained from WH was 55.57 wt.% and 55.03 wt.%, respectively., carbon was relatively high in both weeds. Hence; In this research are concerns the feeding rate, the control gas flow, the temperatures in reactor and reactor operate. MG and WH can produce hi quality of bio-oil and two weeds of resist in Thailand can be also used to generate the other fuel energy in the future.

Index Terms—Bio-oil, pyrolysis, manila grass [zoysiamatrella (l.) merr], water hyacinth [eichhornia crassipes (mart.)solms].
