Basic features of thermal degradation of mixtures of vacuum tower bottoms with pine sawdust have been studied by dynamic thermogravimetry. The kinetic parameters of the process have been determined using the integral model-free Ozawa–Flynn–Wall method. The enthalpies and ethropies of activation of the thermal degradation of the vacuum residue, the sawdust, and their mixtures have been calculated on...
Hydrothermal processing of electron-beam irradiated pine sawdust in a mixture with vacuum tower bottoms (VTB) in an autoclave with continuous removal of the vapor phase at a hydrogen pressure of 7.0 MPa has been investigated. It has been found that as the sawdust irradiation dose increases to 1.0 MGy, the degree of VTB conversion during the hydrothermal treatment of the mixture increases and the amount...
