Aspen requires input of reactor dimensions in lieu of reactor volume. To start the simulation, initial values of 0.1 meter in diameter and 1000 meter in length are assumed. It is found that the conversion of C4H10 reaches a maximum of about 72%. 70% of C4H10 conversion is achieved with reactor length of 410 meter, or 603 second of residence time.

Synthetic natural gas from biomass by catalytic conversion in supercritical water ...

Biomass can be effectively converted to synthetic natural gas (Bio-SNG) in water near or above its critical point (374 C, 22.1 MPa). If an active and selective catalyst is used, no tars or char are formed. The onset of the gasification reaction was visualized in sealed quartz capillaries as high pressure batch rea Green chemistry for fuel synthesis and processing

Feb 22, 2016 Ideal Reactors Batch Reactors. In a batch reactor, the reagents are added together and allowed to react for a given amount of time. The compositions change with time, but there is no flow through the process. Additional reagents may be added as the reaction proceeds, and changes in temperature may also be made.

Batch Reactors at Constant Volume or Constant Pressure

Fractional conversion versus dimensionless time is plotted for an irreversible, gas-phase reaction in two isothermal batch reactors. Both reactors start at the same initial conditions, but one is at constant volume and the other is at constant pressure. Select the final conversion in both reactors with a slider.
