Gas switching technology: Economic attractiveness for chemical looping applications and scale up experience to 50 kWth

Bioreactor Scale-up for Water-Gas Shift Reaction

A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...

Validation, Modeling, and Scale-up of Chemical Looping Combustion with Oxygen Uncoupling

Rarefied gas dynamics and its applications to vacuum technology

Basic concepts of rarefied gas dynamics are given in a concise form. Some problems of rarefied gas flows are considered, namely, calculations of velocity slip and temperature jump coefficients, gas flow through a tube due to pressure and temperature gradients, and gas flow through a thin orifice. Results on the two last problems are given over the whole range of gas rarefaction. A methodology f...

Syngas Chemical Looping Process for Hydrogen Production: Bench Scale Demonstration and Process Simulation

The Syngas Chemical Looping (SCL) process converts gaseous fuels such as syngas and hydrocarbons into hydrogen and electricity while capturing 100% of the CO2 generated 1, . The SCL process simplifies the overall fuel conversion scheme while reducing pollutants in an indirect but highly effective manner. This is achieved via a specially tailored Fe2O3 based composite particle. As a result, hydr...
