Liquid smoke can be produced by using the pyrolysis process. Biomass, as the raw material, is heated in a pyrolysis reactor to generate pyrolysis vapor. The pyrolysis vapors coming from the reactor are condensed in a liquid collection system to produce liquid smoke. A liquid collection system is a device...

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...

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...
