• Gasification of materials with hydrocarbon content into the product gas characterised by a high tar content, in a counter-flow natural steam gasifier;
• Full conversion of rich tars, organic steam and hydrocarbons into the corresponding volume of synthesis gas in a catalyst, via a partial oxidation process.

The principal and sufficient objective of phase “a” is merely the separation of inorganic matter, ash, minerals, salts and metals from the bulk of hydrocarbons, i.e. volatile substances, to produce product gas, as “dirty” as possible, i.e. product gas saturated by tars. Next, phase “b” converts all the complex hydrocarbon molecules fully into hydrogen and carbon monoxide (partial oxidation). A special characteristic of phase “b” is its selectivity: the reaction does not engage neither free hydrogen nor carbon monoxide in the product gas, but rather first decomposes complex organic molecules, thereby generating further amounts of synthesis gas. The precondition for the above described partial oxidation to take place is a 1% minimum content of any form of organic carbon in the product gas. A sufficient quantity of tars is also important for the catalyst energy balance, since the exothermic reaction maintains the catalyst operating temperature. Otherwise, a portion of the generated synthesis gas would have to be fully oxidised in order to maintain the temperature.
