| 摘要 |
The invention relates to a method for the at least partial gasification of solid organic feedstock (A), in which method a tar-containing low-temperature carbonisation gas is obtained from the feedstock (A) by low-temperature carbonisation in a low-temperature gasifier (1), and the low-temperature carbonisation gas (B) is subsequently converted by partial oxidation and subsequent partial reduction in a high-temperature gasifier (2) to form a synthesis gas (D), whereby, in a cooling device (30) provided downstream of the high-temperature gasifier (2), the synthesis gas is cooled such that alkalis present in the synthesis gas remain in the gaseous phase and coke particles present in the synthesis gas already no longer exhibit viscidity, and that a coarse fraction of coke particles is separated off from the synthesis gas in a cyclone device (4) provided downstream of the cooling device (30), wherein a fine fraction of the coke particles passes through the cyclone device (4) with the synthesis gas. |
