The ThermoRefinery is a new concept and an associated practice representing the 2nd generation of thermochemical processes for the conversion of renewable feedstocks (biomass and wastes) to fuels, chemicals and other biobased products, while solving the most significant problems limiting the potential of this type of technologies to contribute to global and regional targets. This paper aims at demonstrating the ThermoRefinery approach and its applications, aiming at several objectives: optimising pretreatment processes for each feedstock, including leaching and torrefaction; designing optimal production systems; and, putting together optimal product vectors. The major optimization challenges are taking into account ash chemistry, which affects the ash melting point. These include minimising other ash-related problems, controlling tar content in the producer gas, minimizing emissions, and reducing feedstock handling problems.

Rafineria termiczna to nowa koncepcja i związana z nią praktyka reprezentująca drugą generację procesów termochemicznych w zakresie przekształcania surowców odnawialnych (biomasy i odpadów) na paliwa, chemikalia i inne produkty biologiczne, przy rozwiązywaniu najważniejszych problemów ograniczających potencjał tego typu technologii w zakresie przyczynienia się do realizacji celów globalnych i regionalnych. Niniejszy artykuł ma na celu ukazanie podejścia do rafinerii termicznej i jej zastosowań, mając na uwadze kilka celów: optymalizację procesów obróbki wstępnej dla każdego surowca, w tym wymywanie i toryfikację; projektowanie optymalnych systemów produkcyjnych; łączenie optymalnych wektorów produktów. Głównym wyzwaniem optymalizacyjnym jest uwzględnienie składu chemicznego popiołu, który ma wpływ na temperaturę topnienia popiołu. Obejmuje on minimalizację innych problemów związanych z popiołem, kontrolę zawartości substancji smolistych w gazie produkcyjnym, minimalizację emisji i zmniejszenie problemów z obsługą surowca.
