“…Carbonates have little influence on the pyrolysis of biomass and there is no reaction with pyrolysis intermediates below 550 • C. When the temperature is higher than 550 • C, the carbonates gradually react with the intermediate products, so that the amount of the main pyrolysis products of biomass also changes, in which reaction ( 10)-( 14) may occur. The reaction pathway proposed is also consistent with the phenomenon of Li 2 O being found in carbonate residues in the reported study [39]. The effect of alkali metal carbonate on biomass pyrolysis becomes more significant after 750 • C. In the following equations, M represents Li, Na or K. According to the HSC simulation results, the consumption of Li 2 CO 3 is more obvious than that of other two carbonates.…”

“…Для МДО-покриттів найбільша ефективність використання як матеріалу-носія передбачається для оксиду алюмінію γ-Al 2 O 3 [5]. Оксид алюмінію γ-Al 2 O 3 становить великий інтерес, оскільки він є одним з найефективніших носіїв для активного компонента, зокрема використовується в каталізаторах відновлення оксидів азоту [6], окиснювання CO [7], отримання сингазу [8], окиснювання аміаку [9]…”

В роботі оптимізувалася технологія МДО з метою отримання високої розвиненості покриттів та їх гарної адгезії з основою для створення високоефективного гетерогенного каталізатора на оксидному носії системи Pt/Al 2 O 3. Методами МДО на сплаві Д16 і технічному алюмінії А97 отримані оксидні покриття різного фазового складу, різної структури поверхні і шорсткості, товщиною 20-100 мкм. Показано, що структура і морфологія поверхні покриттів визначається умовами електролізу, що дозволяє проводити їх оптимізацію для підвищення ефективності використання. Виявлено закономірності впливу-фазово-структурного стану і морфології МДО-покриттів на ефективності їх використання в системі Pt/Al 2 O 3 як каталізаторів очищення оксиду азоту, що дозволило досягти величини коефіцієнта очищення понад 90 %.

Furan is a typical heterocyclic compound in pyrolytic tar and has a strong tendency of coke deposition in thermochemical conversion, leading to catalyst deactivation for tar upgrading. The present study proposed a promising method for furan cracking and reforming using molten alkali carbonates (Li 2 CO 3 −Na 2 CO 3 −K 2 CO 3 ). The results showed that a little gas was generated in the conversion process and CO dominated the gas species. In comparison to the experiment under salt-free conditions, the decarbonylation of furan in molten salt conversion was strengthened and oxygen could be removed as H 2 O into the liquid products. Under the catalysis of alkali metal cations, the conversion of furan to aromatic compounds was promoted at each temperature. Moreover, excess CO 2 enhanced the reverse water−gas reaction, resulting in the consumption of H 2 and the increase of CO in gaseous products. In addition, coke produced in molten salts was of higher reactivity and could hardly affect the stability of the molten salt system. On the basis of the good thermal conversion behavior as well as anticoking performance of molten carbonates, these findings offer a new way for the proper reforming and upgrading of furan through molten salt thermal treatment.
