Pyrolysis of Rice Husk and Corn Stalk in Auger Reactor. 1. Characterization of Char and Gas at Various Temperatures

Abstract

In the series study, rice husk and corn stalk have been pyrolyzed in an auger pyrolysis reactor at various pyrolysis temperatures of 350, 400, 450, 500, 550 and 600 °C in order to investigate the effect of the pyrolysis temperature on the pyrolysis performance of the reactor and physicochemical properties of pyrolysis products (this part focus on the char and gas, the next part focus on the pyrolysis liquid). The results have shown that the pyrolysis temperature significantly affects the mass yields and properties of the pyrolysis products. The mass yields of pyrolysis liquid and char are comparable to

Biomass pyrolysis: A review of the process development and challenges from initial researches up to the commercialisation stage

“…http://engine.scichina.com/doi/10.1016/j.jechem.2019.01.024 Yu et al studied the pyrolysis of rice husks and corn stalk at temperatures of 350, 400, 450, 500, 550, and 600 °C. The solid residence time was 60 s. The optimum temperature was 500 °C for both feedstocks (bio-oil yield: 51 wt% for rice husk and 54 wt% for corn stalk) [266] . Roux et al measured the bio-oil and char yield by pyrolysing the wood in auger reactor.…”

Catalytic fast pyrolysis of rice husk: Influence of commercial and synthesized microporous zeolites on deoxygenation of biomass pyrolysis vapors

“…8 Gaseous product has low yield and has complex process conditions of purification and separation for large-scale applications. [16][17][18] The reason for high oxygen content as previously described is due to the presence of oxygenated groups that form the low heating value fuels. The use of gaseous products of biomass and their upgradation using zeolite is a better and low-cost alternative to reduce the effect of these oxygenated compounds.…”

“…The pyrolysis bio-oil cannot be directly used since it is highly unstable and has complex composition (high water and oxygen contents (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)wt% and (35-60)wt%, respectively). 8 Gaseous product has low yield and has complex process conditions of purification and separation for large-scale applications.…”

Mechanism of enhanced performance on a hybrid direct carbon fuel cell using sawdust biofuels

“…The carbon-oxygen functional groups (carboxyl, lactone, phenol, carbonyl, anhydride and etc.) are dissociated in the first stage, then these carbon-oxygen functional groups from lignocellulose structure release CO, CO2, CH4, H2, and dissociate into some traces of light hydrocarbons (mainly including C2H4, C2H6, C3H6, C3H8, and n-C4H10) [13,23]. Except for small contribution of CO electro-oxidation via Eq.…”
