Abstract: Muffle furnace consisting of a furnace, a perforated plate at the base of the interior, a structure which divides the interior of the furnace into chambers; a further perforated plate beneath the cover of the furnace. It is used for the heat treatment of materials, a gas or gas mixture being fed before, during and/or after the heat treatment into the chambers through the perforated plate beneath the cover and being fed from the chambers through the perforated plate at the base.

Abstract: La presente invención se refiere a un catalizador para la manufactura del metil mercaptano a partir de los óxidos de carbono, que comprende compuestos de Mo y K y óxidos o sulfuros de metales elegidos del grupo del manganeso. La mejora del presente proceso consiste del hecho que el dióxido de carbono puede ser convertido con conversiones y selectividades más elevadas al metil mercaptano cuando se compara con las tecnologías del estado del arte, con cantidades solamente menores de monóxido de carbono que son formadas como el producto secundario. Simultáneamente, el monóxido de carbono puede ser convertido fácilmente en dióxido de carbono e hidrógeno por la reacción con agua utilizando las tecnologías del cambio de gas-agua establecidas, incrementando así la selectividad total hacia el metil mercaptano.

Abstract: The present invention refers to a catalyst for the manufacture of methyl mercaptan from carbon oxides comprising Mo and K compounds and oxides or sulfides of metals chosen from the manganese group. The improvement of the present process consists of the fact that carbon dioxide can be converted with higher conversions and selectivities to methyl mercaptan as compared to state-of-the-art technologies, with only minor amounts of carbon monoxide being formed as side product. Simultaneously, carbon monoxide can be easily converted into carbon dioxide and hydrogen by reaction with water using established water-gas-shift-technologies thus increasing the overall selectivity to methyl mercaptan.
