This paper focuses on the control of a low-temperature ethanol steam reformer for in-situ hydrogen production. For this purpose, three optimization-based control configurations are proposed, namely, a linear model-based predictive controller, a linear quadratic regulator with output error integral action and a cascade control combining the two previous configurations. In all cases, control obje...

In this paper, the implication of various grades of hydrogen rich gas on the in-cylinder flame speed, and on the knock propensity, are discussed. The laminar flame propagation speed of methane with various grades of hydrogen-rich gas addition has been calculated. The effect of adding hydrogen, hydrogen rich gas from an ideal reformer (synthesis gas), as well as that from a non-catalytic plasmat...

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehydrogenation, hydrogenation...

This paper focuses on the design of a controller for a low temperature ethanol steam reformer for the production of hydrogen to feed a Protonic Exchange Membrane (PEM) fuel cell. It describes different control structures for the reformer and treats the control structure selection of this Multiple Input Multiple Output (MIMO) system. For each control structure, decentralised 2x2 controllers with...

This paper reports three normative models for project-based learning (PjBL) in university-industry relations in computing. The models are inspired by normative theories on business ethics, and are designated as archetypes that describe the objectives and responsibilities of parties in collaboration: 1) The Slaver model prescribes that a university should sell students as slaves for business and...

The research analyzed employers innovative behavior of the organization and importance of influencing factors on it. As research methods were chosen method of structured interrogation, the method of pairwise comparisons, expert evaluation and correlation and regression analysis. The research results were gender difference in innovative employer behavior: more favorable innovation perception in ...
