Abstract: A separator system for treating a gas from a biomass gasification system, including: first and second cyclones, where the first cyclone includes an inlet for receiving a gas from a biomass gasification unit, the first cyclone being arranged for removing particulate matter from the gas from the biomass gasification unit in order to provide a first cleaner gas, piping arranged to lead the first cleaner gas to the second cyclone, where the second cyclone is arranged to remove particulate matter from the first cleaner gas in order to provide a second cleaner gas, a pipe arranged to lead the second cleaner gas to a special piping element, the latter including a burner, thereby providing a third cleaned gas, and a gas distribution unit arranged to lead the third cleaned gas to one or more tar reformer units. Also, a method of treating a gas from a biomass gasification system.

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.
