A Pilot Study of Syngas Production from Bio-oil Thermal Cracking in a Bubbling Fluidized Bed Reactor

A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

Hydrogen and Ethanol as Potential Alternative Fuels Compared to Gasoline under Improved Exhaust Gas Recirculation

In the present study, a computational fluid dynamics (CFD) method have been utilized to investigate the effects of exhaust gas recirculation (EGR) and initial charge pressure by means of using a supercharger on the emissions and performance of a SI engine. This engine is fueled separately by gasoline and two potential alternative fuels, hydrogen and ethanol. The results of simulation are compar...

Liquid Fuel Production from Synthesis Gas via Fermentation Process in a Continuous Tank Bioreactor (CSTBR) Using Clostridium ljungdahlii

The potential bioconversion of synthesis gas (syngas) to fuels and chemicals by microbial cell has attracted considerable attention in past decade. The feasibility of enhancing syngas bioconversion to ethanol and acetate using Clostridium ljungdahlii in a continuous tank bioreactor (CSTBR), kinetics and mass transfer coefficient of carbon monoxide (CO) utilization were evaluated. Two different ...
