    摘要： The invention relates to a catalyst regeneration process for a tar reforming catalyst within a catalyst bed in a tar reformer. The process comprises the steps of:—Admitting a main gas stream with controlled temperature and oxygen content to an inlet into the tar reformer;—Passing the main gas stream through the catalyst bed to form an oxygen depleted gas stream;—Exiting the oxygen depleted gas stream from the tar reformer; and—Recycling at least a part of the oxygen depleted gas stream exiting from the tar reformer back into said main gas stream upstream said tar reformer. The temperature of said main gas stream at the inlet is controlled to be within the range from about 500° C. to about 1000° C.

    摘要翻译： 本发明涉及焦油重整器中催化剂床内焦油重整催化剂的催化剂再生方法。 该方法包括以下步骤： - 将具有受控温度和氧含量的主气流引入焦油重整器的入口; - 通过催化剂床通过主气流以形成贫氧气流; - 从焦油重整器中排出贫氧气流; 和 - 将从焦油重整器排出的至少一部分贫氧气流返回到所述焦油重整器上游的所述主气流中。 所述主气流在入口处的温度被控制在约500℃至约1000℃的范围内。
