    • The invention relates to a method for the continuous obtention of synthesis gas by the direct gasification of carbon fractions contained in oil sands and/or oil shales in a vertical process chamber (2) having a calcination zone and an oxidation zone (6), in which the calcinated, fractions rich in carbon oxidize with oxygen-containing gas. The gaseous reaction products are withdrawn at the top of the vertical processing chamber (2) that has the shape of a vertical shaft furnace which is continuously flown through from the top to the bottom by a bulk material which itself is not oxidized. Oxygen-containing gas (10) is at least partially introduced beneath the oxidation zone, whereby the rising gas flow is facilitated. The bulk material is at least partially provided by the natural inert rock content in the oil sands and/or the oil shales. Added alkaline substances convert under reductive conditions the gaseous sulfur compounds, which were obtained at temperatures above 400° C. from the constituents of the oil sands and/or the oil shales, by chemical reaction into solid sulfur compounds which are at least partially discharged with the gaseous reaction products and are removed from the gas phase at temperatures above 300° C. by fine material separation (18).
    • 本发明涉及通过在含有煅烧区和氧化区(6)的垂直处理室(2)中直接气化包含在油砂和/或油页岩中的碳馏分来连续获得合成气的方法, 其中煅烧的,富含碳的部分用含氧气体氧化。 气态反应产物在垂直处理室(2)的顶部被取出,该垂直处理室(2)具有垂直竖炉的形状,该垂直竖炉由本身不被氧化的大块材料从顶部连续地流过底部。 含氧气体(10)至少部分地被引入到氧化区之下,由此促进上升的气体流动。 散装材料至少部分地由油砂和/或油页岩中的天然惰性岩石含量提供。 添加碱性物质,在还原条件下,通过化学反应将高于400℃的温度从油砂和/或油页岩的成分获得的气态硫化合物转化成固体硫化合物,固体硫化合物至少部分地与 气态反应产物,并通过细料分离(18)在高于300℃的温度下从气相中除去。
