2021-3-26 As decomposition proceeded, the decomposition rate increased rapidly before reaching its peak and then decreased rapidly until the end of the decomposition. It can be observed that the decomposition rate reached its peak in a shorter time with the increase of the roasting temperature, and the maximum decomposition rate was 0.00468 s −1 at 973.15 K.

2017-10-3 The objective of the present work is to study thermal decomposition and thermal desorption of mercury (Hg) in two different soils from the old mercury mining district of Almadén (Spain). One of these soils (S1) was taken from a “dehesa” where natural Mediterranean vegetation is combined with agrosilvopastoral activities.

2017-5-30 Inherently, coal is composed of moisture, volatile matter, fixedcarbon and ash. When coal undergoes thermal decomposition, firstthe liberation of water molecules occurs, followed by reactions ofvolatiles and fixed carbon [9,10]. The coal decomposition processcomprises homogeneous decomposition of volatiles and heteroge-neous decomposition of fixed carbon. Several authors have stud-ied the behavior of coal

2021-1-10 Studied kinetics of excavated waste pyrolysis, and proved that their thermal decomposition does not reflect the thermal decomposition pattern of fresh waste. Independently (Breyer et al., 2017), performed co-pyrolysis of excavated plastics with used lubrication oils to produce an alternative fuel for cement kilns. The goal was achieved with a maximum content of excavated plastic of 60 wt%, and the
