Get DetailsJan 11, 2021 Hydrothermal carbonization (HTC) is a thermochemical conversion process that uses heat to convert wet biomass feedstocks to hydrochar. HTC is performed in a reactor at temperatures ranging from 356 to 482 F, i.e., 180 to 250 C, under autogenous (automatically generated) pressure, with feedstock residence time ranging from 0.5 to 8 hours [1,2].
Get DetailsJan 21, 2022 The primary tar formed in MFBR was immediately introduced into a secondary tubular reactor (STR), in which the secondary reactions occurred. The chem. components of both condensed primary tar and secondary products were characterized by atm. pressure photoionization Fourier transform ion cyclotron resonance mass spectrometry (APPI-FT-ICRMS).
Get DetailsOct 15, 2016 This reactor can be made using either steel, firebricks or concrete and composed of the feeding unit (fuel), ... At this stage, tar is produced and volatile species are released. A series of secondary reactions such as decarboxylation, decarbonylation, dehydrogenetaion, deoxygenation and cracking takes place to produce mixture of syngas ...
