Abstract: 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.
