A system includes a particulate removal system configured to remove particulates from a syngas to generate a treated syngas and a particulate flow. The particulate removal system includes a shell. The shell includes a syngas inlet configured to receive the syngas, a syngas outlet configured to discharge the treated syngas, and a particulate outlet configured to discharge the particulate flow. The particulate removal system also includes a particulate collection surface disposed in the shell and configured to adhere the particulates from the syngas to the particulate collection surface as the particulate collection surface rotates toward the syngas and to separate the particulates from the particulate collection surface as the particulate collection surface rotates away from the syngas.
