Special Issue Information
Dear Colleagues,
Thermochemical conversion processes, such as combustion, gasification, and pyrolysis, of biomasses and other solid fuels are always determined by their ash behavior. Ash-related effects of agglomeration, fouling, sintering, slagging, catalytic ash components, etc. will strongly affect the process design and appropriate parameters. The ongoing trend of the substitution of fossil fuels by renewable and secondary ones has to consider completely different ash systems. Ashes of biomasses and other secondary carbon resources typically contain higher contents of K, P, Ca, Mg, and Cl compared to fossil ones and thus tend to form eutectic systems. The process-related ash behavior of solid fuels is strongly affected by differences in origin by authigenic, detrital, and technogenic minerals in the fuels. Key factors of ash behavior in industrial processes are inter alia the selective gas phase transfer of ash species (e.g., heavy metals), fouling, sintering, slagging, agglomeration, catalytic effects, mineral formation and transformation, ash fusion, and slag viscosity. Due to the requirements of an increased efficiency in energy and resources, process optimization uses more and more frequently modeling tools, e.g., thermochemical or neuronal networks, to simulate and optimize ash behavior. In addition to that, processes for recovery of valuable ash components have to be developed to enhance efficiency. This Special Issue assembles papers covering recent approaches to improved process control based on a complementary understanding of ash behavior from the initial fuel up to the high temperature range by various measurement and modeling tools.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.
