“…The results showed that pyridinic-N was a basic N-containing species, and the unshared electron pair on the pyridinic-N atom accepted the protons and became alkaline, thus reducing the acid strength of N-Fe/BC . As the acid sites of the decomposition and deoxidation reactions, the strong acid sites tended to produce gas products rather than liquid products, and they could easily accumulate carbon deposits and lead to the deactivation of catalysts . Therefore, appropriate acidic sites in the catalyst could improve the directional catalytic activity and reduce the probability of catalyst deactivation.…”

“…Pine needles were non-catalytically and catalytically (using Al 2 O 3 and Ni/Al 2 O 3 as catalysts) transformed into bio-oil, biochar and noncondensable gases via pyrolysis with respective conversion yields given in Table 3 (as per laboratory scale experiments reported in previous studies). 8,27 Detailed description of the experimental set-up and process has been elucidated in the previous study. 8,27,28 The inventory for the Al 2 O 3 catalyst was adopted from the ecoinvent 3.8 database in GaBi soware, while the inventory for the Ni/Al 2 O 3 catalyst was further evaluated by including nickel impregnation in the Al 2 O 3 preparation process (as shown in Fig.…”
