Using steam reforming to produce hydrogen with carbon dioxide capture by chemical- looping combustion. In this paper, a novel process for hydrogen production by steam reforming of natural gas with inherent capture of carbon dioxide by chemical- looping combustion is proposed. The process resembles a conventional circulating fluidized bed combustor with reforming taking place in reactor tubes located inside a bubbling fluidized bed. Energy for the endothermic reforming reactions is provided by indirect combustion that takes place in two separate reactors: one for air and one for fuel. Oxygen is transferred between the reactors by a metal oxide. There is no mixing of fuel and air so carbon dioxide for sequestration is easily obtained. Process layout and expected performance are evaluated and a preliminary reactor design is proposed. It is found that the process should be feasible. It is also found that it has potential to achieve better selectivity towards hydrogen than conventional steam reforming plants due to low reactor temperatures and favorable heat- transfer conditions. · A colorimetric sensor for measuring one or. such as chrome oxide. temperatures using data from the Handbook of Vapor Pressure (Yaws.

The bismuth atom usually utilizes the three 6p electrons in bond formation and retains the two 6s electrons as an inert pair; hence, the oxidation state +3 exhibited by bismuth in the vast majority of its compounds. However, a variety of organobismuth compounds can contain the element in the +5 oxidation state. Coordination numbers are 2, 3, 4, 5, and 6. Bismuth not only has metallic characteristics, but also exhibits many properties similar to those of semiconductors and insulators. Consequently, it is often classified as a semimetal or metalloid. Bismuth compounds are usually colorless unless the metal is bound to a chromophore. Copyright © 2. 00. Elsevier B. V. All rights reserved.
