Recovery of molybdenum from spent hydro-refining catalysts by soda ash roasting - A statistical approach
In the present study, a hydro-refining spent catalyst with an alumina base has been taken into consideration. It is mostly used for the recovery of molybdenum. The spent catalyst constitutes around 21 pct of molybdenum as molybdenum oxide. The study has revealed that at temperature lower than 600C, it is possible to recover an appreciable quantity of molybdenum from the spent catalyst. The stat...
متن کاملRefining Discretizations of Continuous-Valued Attributes
The Rand index is a measure commonly used to compare crisp partitions. Campello (2007) and Hüllermeier and Rifqi (2009) respectively, proposed two extensions of this index capable to compare fuzzy partitions. These approaches are useful when continuous values of attributes are discretized using fuzzy sets. In previous works we experimented with these extensions and compared their accuracy with ...
متن کاملMpc Control of the Refining Stage of an Electric Arc Furnace
The aim of this article was to design a MPC controller for the refining stage of an electric arc furnace. A reduced version of the generic EAF model will be used it simplifies the controller. The carbon content is controllable only in one direction it can only decrease asymptotically. The goal of the MPC controller will be to steer the temperature to the desired value before the carbon content ...
متن کاملRefining Objects
Inspired by Cardelli’s pioneering work, many type disciplines for object-oriented programming are based on enrichments of structural type theories with constructs such as subtyping and bounded polymorphism. A principal benefit of such a formulation is that the absence of “message not understood” errors is an immediate corollary of the type safety theorem. A principal drawback is that the result...
متن کاملInfluence of Refining Agent in Soda Lime Glass for Ultraviolet Ray Transmittance
We have studied the refining effects of refining agents and ultraviolet transmitting property of soda lime glass, for the purpose of developing ultraviolet transmitting glass with soda lime glass composition which is one of an inexpensive glasses. It was found that for glass that requires ultraviolet transmitting property, antimony oxide, which is commonly used as a refining agent, cannot be us...
