Biomass, as a renewable energy source, is available worldwide, is carbon neutral, and can be converted to various types of products depending on the market and on the specific applications. Among different technologies of biomass utilization, thermochemical conversion of biomass is the most efficient method with the shortest time scale of the process. Thermochemical conversion can be used to produce gas or liquid fuels, and it can be used for direct production of heat and electricity. Biomass thermochemical conversion is an active and fast growing field of research. New experimental methods with high spatial and temporal resolution such as laser diagnostics are being introduced, and numerical modeling of the physical and chemical details in biomass conversion is being conducted. In this review, we aim to provide an overview of the recent activities in the field of thermochemical conversion of biomass. Important parameters in the large scale conversion systems, such as temperature distribution, overall conversion rate of fuel, and distribution of different species, are strongly connected to the processes that occur on the scale of a single particle. Understanding the link between transport phenomena, chemical kinetics, and physical transformation on single particle scale can help to unravel issues such as emission and efficiency on the large scale. Hence, the focus of this review is on the single biomass particle, relevant to combustion and gasification systems. Special attention is paid to high fidelity numerical models and state-of-the-art experimental techniques that have been developed or employed over recent years to understand different aspects of biomass thermochemical conversion.

“…In the next pellets with a diameter of 8 mm were prepared. The procedures for sample preparation, leaching and impregnation are described in detail in previous works (Sadeckas et al, 2018;Striūgas et al, 2019). The alkali content found in the untreated, washed and doped samples on a dry basis is presented in Table 2.…”

“…Our previous works (Sadeckas et al, 2018;Striūgas et al, 2019) showed promising results using an ICCD camera for alkali detection as well, but spontaneous emissions of alkali radicals were marginal at combustion temperatures up to 750C. (Sommersacher et al, 2016(Sommersacher et al, , 2015 performed biomass combustion in a single particle reactor (SPR) coupled with an inductively 6 coupled plasma mass spectrometer (ICP-MS) at different temperatures (700 °C, 850 °C, 1000 °C).…”

“…It is thus of great interests to elucidate the effects of thermal processing conditions on the K transition associated with structural changes during biomass combustion. Currently available publications, however, focused mainly on the release behaviour of K from burning biomass samples in a preheated reactor at temperatures around 1000°C [9,[15][16][17][18][19][20][21][22]. Little is known on the effects of operational conditions on the structural change of biomass particles and the transition of K. This study will investigate the effects of the final temperature and heating rate on the release and transition of K during biomass combustion.…”
