Introduction The reciprocating biomass conversion reactor (RBCR) is a novel means of converting biomass to bio-oil. The RBCR is a repurposed highcompression 4-stroke internal combustion engine into which a fluidizing gas and a small volume fraction of pulverized biomass are introduced, and the crankshaft is cycled by an external energy source to supply the process heat for thermo-chemical conve...

A simple model and results for the decomposition of pulverized cellulosic biomass within a non-oxidizing gas of transient temperature and pressure is presented. This model is used to predict the performance of a novel thermo-chemical biomass conversion scheme termed the reciprocating biomass conversion reactor (RBCR). Calculations indicate that complete thermo-chemical conversion can be complet...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

fast pyrolysis is an attractive technology for biomass conversion, from which bio-oil is the preferred product with a great potential for use in industry and transport. corn wastes (cob and stover) and eucalyptus wood are widely being produced throughout the world. in this study, fast pyrolysis of these two materials were examined under the temperature of 500 °c; career gas flow rate of 660 l h...

Pyrolysis of Alcea pallida stems was performed in a fixed-bed tubular reactor with and without catalyst at three different temperatures. The effects of pyrolysis parameters including temperature and catalyst on the product yields were investigated. It was found that higher temperature resulted in lower liquid (bio-oil) and solid (bio-char) yields and higher gas yields. Catalysts had different e...

in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...

The present study deals with the assessment of antimicrobial activity (antibacterial, antifungal and antiyeast) of bio-oil from Pongamia glabra, Mesua ferrea and Parachlorella spp deoiled cake. The bio-oil from the respective deoiled cakes were obtained via the process of pyrolysis (ambient to 500°C at a heating rate of 40°C/min) in a vertical tubular fixed bed reactor in nitrogen atmosphere. B...
