utilization ratio of catalyst surface 催化剂表面有效利用率
The adoption of this new technology not only increases methanol output and catalyst utilization ratio, but, also stabilizes ammonia synthesis operation and increases the net ammonia value.
采用该新技术，不仅可提高甲醇产量和催化剂利用率，而且可稳定氨合成操作，提高氨净值。
Catalyst activity was determined by not only specific surface area of catalyst but also the distributions of active center and utilization ratio of internal surface.
催化剂活性不仅与比表面有关，还与其活性中心分布情况、内表面利用率有关。
