Previous research of thermal co-pyrolysis of biomass-plastics where plastics function as hydrogen donor to induce synergistic effect on non-oxygenated fraction of bio-oil has reached a condition that there was a difficulty of separating non-oxygenated compounds from oxygenated compounds either at low heating rate. It was suspected that the content of high molecular weight of compounds especially polyaromatic hydrocarbons (PAH) in bio-oil retarded this separation. At low heating rate, most of co-pyrolysis until recently have been ...

Penelitian pembakaran briket batubara bertujuan untuk untuk mempersingkat waktu penyalaan. Penelitian dilakukan dengan memanfaatkan briket promotor bentuk bola yang mengandung oksigenat etil asetat yang berfungsi sebagai penyedia oksigen secara internal dalam material briket karena ketidak-cukupan oksigen saat briket promotor mengalami devolatilisasi (fungsi kinetika kimia) dan sebagai penguat terjadinya perpindahan panas konveksi dari bara api pada briket promotor ke briket pemasakan yang diletakkan disekitarnya karena adanya cekukan (dimples) pada permukaannya (fungsi perpindahan panas ). Briket promotor ...

Bio-oil produced by biomass pyrolysis contains high oxygenates, namely, carboxylic acids, alcohols, and ketones resulting in low calorific fuel, and therefore bio-oil requires upgrading to sequester these oxygenates. By conducting the co-pyrolysis of biomass and plastic feed blend, the donation of hydrogen by plastic free radicals to the oxygen of biomass free radicals may sufficiently reduce oxygenate compounds in the bio-oil and increase its yield. Therefore, the synergetic effects are functional. Currently, co-pyrolysis reactors have ...

Torrefaction, which is used to improve the properties of sugarcane bagasse as fuel in pulverised fuel combustion and as carbon feed in gasification, is a low heating rate pyrolysis of biomass carried out at a temperature of 200–300oC, at an atmospheric pressure, and in an inert environment. In the present work, sugarcane bagasse was torrefied at heating rates of 3, 6, and 10oC/minute, respectively, to achieve a final temperature of 275oC and after the final ...
