摘要：The results presented in the following paper are making the aim of a broadly research concentrated to investigate the temperature effects on agricultural waste pyrolysis performed in a batch reactor. Briefly, the motivation along with experimental features and main results generated from the rape straw low temperature pyrolysis (300°C-500°C) have been offered in the first part submitted at the MSE 2019 conference, with the title: Bio-gaseous fuels from agricultural waste pyrolysis (Part I). The current section (second part of the study) presents the results obtained in case of the rape straw high temperature pyrolysis (600°C-800°C). Overall, as expected, the augmentation of the operating temperature, inhibits the bio-oil and biochar formation, enhancing the pyrolysis gas production. The distribution of gaseous components varies depending on temperature and residence time. The transition stages and the formation of the main pyrolysis gaseous species are also presented and discussed. The most dominant chemical element from the pyrolysis gas is N2, due to its constant presence as non-oxidant agent in the process. Considering the same premise, the rape straw pyrolysis gaseous species distribution in the temperature range of 600°C-800°C varies between: 47%-58% CO2, 18%-28% CO, 14%-35% H2, while the pyrolysis gas density 1.1-1.4 kg/m3and higher heating value 23-52 MJ/kg.
