Catalytic pyrolysis of wood biomass in an auger reactor using calcium-based catalysts

Investigation on the fast co-pyrolysis of sewage sludge with biomass and the combustion reactivity of residual char

“…For calcium (Ca) and potassium (K), the contents in WS are 1.5-and 3-fold higher than those in WS respectively. Ca and K are good catalysts for the decomposition of the secondary char (Zaror et al, 1985;Veses et al, 2014). Therefore, with the increase of WS adding percentage, SS produces more gas products and less char.…”

Calcium-catalyzed pyrolysis of lignocellulosic biomass components

“…This choice is based on the successful use of zeolites in the petroleum refining industry. While other types of catalysts have been studied (Di Blasi et al, 2008;Lu et al, 2009;Meesuk et al, 2011;Veses et al, 2014), zeolites are still used primarily.…”

Pressurized pyrolysis of rice husk in an inert gas sweeping fixed-bed reactor with a focus on bio-oil deoxygenation

“…This is deemed to be responsible for its drawback of low heating value, lipophilicity and instability, restricting its application. Several approaches have hence emerged to upgrade the bio-oil before, during and after pyrolysis (Stefanidis et al, 2011;Veses et al, 2014). A common tactics adopted in most approaches is to eliminate the oxygen from bio-oil.…”
