预测1990年铂的世界供给量为108t,汽车触媒消费量为46t,其中含回收7t,回收率为15％。金属铑的供应量为9.8t,汽车触媒消费量为7.3t,其中含回收0.4t,回收率为5％。预测到2000年铂的世界供给量为133t,汽车触媒消费量为62t,其中含回收12t,回收率为20％。金属铑的供应量为12.7t,汽车触媒消费9.7t,其中含回收0.8t,回收率为8％。汽车用触媒回收率有所提高,但到
In 1990, the global supply of platinum was estimated to be 108 tons and the consumption of automobile catalyst was 46 tons, of which 7 tons were recovered and the recovery rate was 15%. Supply of rhodium metal 9.8t, vehicle catalyst consumption of 7.3t, including the recovery of 0.4t, the recovery rate of 5%. It is predicted that by the year 2000, the global supply of platinum will be 133 tons and the consumption of automobile catalyst will be 62 tons, of which 12 tons will be recovered and the recovery rate will be 20%. The supply of metal rhodium is 12.7t, the consumption of automobile catalyst is 9.7t, of which the recovery is 0.8t and the recovery rate is 8%. Automotive catalyst recovery rate has improved, but to
