Abstract

The method for the catalytic gasification of organic material is characterised in that the gasification is carried out in the liquid phase (water) at elevated pressure and temperature and without added oxygen. It is particularly suitable for the gasification of biomass, steam reforming and effluent treatment. Suitable catalysts are compounds from group I A of the periodic table, and here particularly potassium.

Description

Die Erfindung ist gekennzeichnet durch eine Vorgehensweise, bei der mit Hilfe eines Katalysators die Umwandlung von organischem Material in flüssiges Wasser bei hohem Druck und erhöhter Temperatur vorgenommen wird.The invention is characterized by a procedure, in which the conversion of organic material in liquid water at high pressure and elevated temperature is made.

Es ist allgemein bekannt, organisches Material mit Hilfe von Dampf entweder in Gasphase oder in ein Festbett zu vergasen. Dies erfolgt bei hoher Temperatur und mäßig erhöhtem Druck. Die sogenannte steam-reforming-Reaction läuft nach der GleichungIt is common knowledge to use organic material of steam either in the gas phase or in a fixed bed gasify. This is done at high temperature and moderately elevated Print. The so-called steam reforming reaction runs according to the equation

C x H y + zH₂O = aCH₄ + bH₂O + cCO + dCO₂C x H y + zH₂O = aCH₄ + bH₂O + cCO + dCO₂

ab, und die Biomaß-Vergasung nach der Gleichungand the biomass gasification according to the equation

C x H y O z + qH₂O = aCH₄ + bH₂O + cCO + dCO₂.C x H y O z + qH₂O = aCH₄ + bH₂O + cCO + dCO₂.

Beide Prozesse verlaufen endothermisch. Die Produktzusammen­ setzung variiert übereinstimmend mit den gewählten Prozeß­ bedingungen. Das Neue an diesem Prozeß ist, daß die mit Hilfe eines Katalysators erzeugte Reaktion in flüssigem Wasser bei hohem Druck und erhöhter Temperatur erfolgt. Wichtig ist, daß das erzeugte Gas durch den vorgenannten hohen Druck erzeugt wird. Dadurch spart man eine sehr teure Kompressions­ stufe. Man kann deshalb das Gas direkt zu einer Synthese-Stufe leiten, z. B. Methanol- oder Kohlenwasserstoff-Synthese. Both processes are endothermic. The product together Settlement varies according to the chosen process conditions. What is new about this process is that with the help of a catalyst generated reaction in liquid water at high pressure and elevated temperature. Important is that the gas produced by the aforementioned high pressure is produced. This saves a very expensive compression step. You can therefore direct the gas to a synthesis stage lead, e.g. B. methanol or hydrocarbon synthesis.
