Sulfur Deactivation Effects on Catalytic Steam Reforming of Methane Produced by Biomass Gasification
Sulfur, which is incorporated in the biomass structure, is released into the product gas during gasification as hydrogen sulfide. Hydrogen sulfide is known to deactivate nickel based steam reforming catalysts by chemisorption on the metal surface during steam reforming process. ... Per saperne di più
Structural Analysis of a Pressure Sensor for High Temperature Environments
Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible ... Per saperne di più
A Theoretical Model for the Control of Color Degradation and Microbial Spoilage Occurring in Food Convective Drying
The aim of this work was the development of a predictive model aimed at identifying a proper control strategy of food drying process. In particular, it was intended to determine the effect of operating conditions both on the color degradation, chosen as a reference quality parameter, and ... Per saperne di più
Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum
The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the ... Per saperne di più
Optimal Placement of Piezoelectric Plates to Control Multimode Vibrations of Rotating Beam
Turbomachines blades are forced by a load resulting from the interaction with the fluid. The consequent vibrations, and the associated fatigue phenomena, can give catastrophic failures and the reduction of the blades life. It could be increased if damping system are used. The ... Per saperne di più
