Production of magnesium in retorts Pidgeon with use of combustible gases from the carbonization of biomass

摘要

Production of magnesium in retorts Pidgeon with use of combustible gases from the carbonization of biomass this summary concerns an application of invention patent for a process of producing magnesium in retorts, as in the case Pidgeon, being part of the energi The necessary for heating system and energy consumption of the reaction.From the burning of gases from the carbonization of biomass furnace type container. The invention described in this patent is to couple two processes: carbonization of biomass for the production process of magnesium, and the connection or intercession between them the energy contained in the fuel gases that are generated during the carbonization of biomass.This energy is consumed in the endothermic reaction of reduction of magnesium oxide (MgO) for the production of magnesium metal. The use of the energy takes place by burning or combustion of the combustibles in a furnace, where the retorts Pidgeon.The furnace must be attached to the oven container through a pipe, which leads the fuel gases generated in the container during carbonization, which are suctioned off by an exhaust fan. The retorts Pidgeon, consist of a device in tube shape, and is closed at one end and open at the other.The closed end is inserted inside the furnace and receives the mixture source of magnesium. The other end, will remain outside the furnace and is coupled to a pumping system to be set a negative pressure inside the retort, which is the necessary condition The process of thermal reduction in MgO.At the end of the retort is the sublimation and crystallization of magnesium metal by heat exchange with the surface chilled, after combustion in the furnace and power supply to the retorts, the hot gases generated should be used in the pre drying or car Bonizau00e7u00e3o biomass, or even in other processes, such as in the heating of secondary air of combustion.In electric power generation, among others.
