The present study explores the ability of activated carbon of coconut shell for the removal of nickel(II) and cobalt(II)under different experimental conditions from modeled sulfate solutions.Experiments were carried out in order to obtain the adsorption capacity and the adsorption rate. It was developed for 23 factorial design, considering as main effect initial concentration of...
The importance of the processes of solid state fermentation taking place in this indispensable application of optimization in the design of new systems and for decision-making in the existing ones. The technological process have a production capacity of 100 t/d of dry product, including the preparation of the culture medium, the protein enrichment in fixed bed bioreactors...
The cultivation of Aloe vera for its use in medications, functional foods and cosmetics has been spread out in the last years. The gel has been used in the food elaboration by its nutritional and restorative value. The aim of this research was to develop a probiotic fermented milk with juice of Aloe vera with quality and acceptability indexes that can be compared with established...
Two of the big problems to face at the moment for the humanity, are the energy crisis because of the exhaustion of the fossil fuels and the contamination of the environment due to the different noxious substances that are poured to the rivers, seas, soils, atmosphere. That's why that man has been looked for alternative sources to reduce the effects of the energy crisis and the...
The biological conversion of the Urban Solid Residuals (USR) for energy purposesshe comes winning importance every day, once the urban residuals became considered a source of alternative energy. To foresee the generation of resulting biogas of the process of biological decomposition of the solid residuals of organic origin in the sanitary fillers is fundamental to estimate the...
The effect of the use of Cuban crude in the process of leaching, sedimentation and distillation of the processed minerals at René Ramos Latour Company was evaluated. Two periods of tests were performed; one when oil was introduced into the furnace by spear and the other when it was introduced by spear and chamber. The results demonstrated the feasibility of using the Cuban crude...
This paper presents an evaluation of the influence of a static magnetic field of moderate intensity on the process of recrystallization of a supersaturated solution of sucrose with impurities. In the work is designed and executed experiments determining the influence of a static magnetic field on the nucleation rate and the morphology of microcrystals of sucrose. It characterizes...
The anaerobic digestion in UASB reactors is well known since the 80´, at industrial scale, in Latin American countries, for the treatment of liquid wastes, including the ethanol vinasses. That´s the importance to present the equations used in the design and the results of the actual potentiality of a biogas plant, using as a case of study an, the vinasses treatment of a...
In the present experimental work it was obtained, on a Production Demonstration Unit (UDP) of leaching commercial plant, an exponential statistical mathematical model with a distribution coefficient (R2 = 0,9998), characterized by the equation TR = 13297*(Qpulpa)-0.999;min, to determine the real residence time (TR) of the pulp in the miniseries of first stage of the leaching...
This work is in charge of the development of a second part of the expressions that they conform a mathematical model for the simulation of a battery of reactors able to reproduce the behavior of a reacting system non catalytic fluid-solid, in a sequence of five continuous reactors with agitation connected in series, where the concentration of the reactant in the liquid phase...
