Mathematic simulation on gasification of bio-oil in fixed bed reactor
MetadataShow full item record
The gasification of bio-oil is important in improving the utilization of biomass energy and the environmental protection. The mixtures of acetic acid, glycerol, urfural and phenol were selected as bio-oil model compounds. The thermodynamic analysis was carried out to understand the steam catalytic reforming hydrogen production process. Using thermal dynamic equation and mass balance principle to calculate reactor model, the mathematical model of bio-oil was studied in a fixed bed reactor. Based on Aspen Plus, the R-Gibbs reactor was selected to simulate the product equilibrium compositions of pyrolysis of bio-oil and thereby calculate the molar heat capacity. A mathematical model was established with the thermodynamic equations and mass balance principle, and the conversion rate of gasification at the catalyst bed was calculated by combining the Runge-Kutta method with the Matlab software. The effect of reaction temperature on gaseous components of the molecular balance was investigated. The gasification experiment was performed with bio-oil compounds in a small scale tubular fixed bed reactor, obtaining the conversion rate of gasification and the favorable reaction temperature at the catalyst bed. The experimental results illustrate that the calculation result of the established model agrees well with the experimental results.
