<p>Palladium black catalyst is separated from suspension in anthraquinone solution, in the anthraquinone process for making hydrogen peroxide, by filtering through filter candles of carbon, having a maximum por width of 15mm . The catalyst particles are from 0.01 to 1mm in diameter, but the catalyst deposits on the outside surface and is periodically removed by reverse flow of filtrate. Typical flow rates and filter candle sizes and arrangements are given.</p> |
