Pyrolysis is a thermal process for converting various biomasses, wastes and residues to produce high-energydensity fuels (bio-oil). In this paper, we have done some important analysis of bio-oil which is obtained from the pyrolysis of agricultural wastes - discarded soybean frying oil, coffee and eucalyptus sawdust in the presence of 5% Hydrogen and Argon. The bio oil was obtained in one step pyrolysis in which temperature of the system kept 15°C and then increased up to 800°C but in two step condensation processes. 1st condensation step is done on temperature 100°C and 2nd is done on 5°C. So we got two types of fractions, HTPO (Oil condensed at high temperature 100°C after pyrolysis) and LTPO (Oil condensed at low temperature 5°C after pyrolysis). After pyrolysis the thermal cracking is done for both types of oil on the same two temperatures, then we again got two type of fractions HTCO (high temperature 100°C condensed oil after cracking) and LTCO (Low temperature 5°C condensed oil after cracking), these fractions are distillated and analyzed in GC-MS. The resulted compounds are given in the paper and are explained with the help of graphs and tables. The ultimate aim of hydrogenation and Argon is to improve stability and fuel quality by decreasing the contents of organic acids and aldehydes as well as other reactive compounds, as oxygenated and nitrogenated species because they not only lead to high corrosiveness and acidity, but also set up many obstacles to applications.
