| 8 | Slow Pyrolysis of Sugarcane Bagasse for the Production of Char and the Potential of Its By-Product for Wood Protection显示文摘Sugarcane bagasse was pyrolyzed using a laboratory fixed bed reactor to produce char and its by-product(pyrolysis liquid).The pyrolysis experiments were carried out using different temperatures(400℃ and 500℃),heating rate(1℃/min and 10℃/min),and holding time(30 min and 60 min).Char was characterized according to its thermal properties,while the pyrolysis liquid was tested for its anti-fungal and anti-termite activities.Pyrolysis temperature and heating rate had a significant influence on the char properties and the yield of char and pyrolysis liquid,where a high-quality char and high yield of pyrolysis liquid can be obtained at a temperature of 500℃ and a heating rate of 10℃/min.The yield of char and pyrolysis liquid was 28.97%and 55.46%,respectively.The principal compounds of pyrolysis liquid were water,acetic acid,glycolaldehyde,1-hydroxy-2-propanone,methanol,formic acid,levoglucosan,furfural,followed by some phenol compounds and guaiacol derivatives.Pyrolysis liquid at a concentration of 0.20%and 0.25%(v/v)caused a 100%inhibition of Coniophora puteana and Trametes versicolor,respectively,when performing inhibition growth tests in Petri dishes.Filter paper treated with 10%of pyrolysis liquid caused 100%of termite mortality,while only 5.65%–7.03%of the treated filter papers consumed by termites at such concentration.Pyrolysis liquid is potentially effective to be used in the formulation of wood protection against fungi and termites. | Febrina Dellarose Boer Jérémy Valette Jean-Michel Commandré Mériem Fournier Marie-France Thévenon | 2021 | Journal of Renewable Materials2021，9，1： | 0 |
