Pot calciner process or powder pelleting process combined with rotary kiln calcining process is recommended to increase actual yield of retard petroleum coke. 建议采用罐式煅烧炉工艺或者粉料成球+回转窑煅烧工艺,以提高延迟石油焦的煅烧实收率。
As compared with traditional esterification, the cost of dehydrogenation was lower than that in process of esterification, and the actual yield reached 82% over 76.9% in esterification. 并将脱氢法与传统的酯化法进行了比较，脱氢法的成本要低于酯化法，且其实际收率达到了82%25，超过酯化法的76.
Based on foregoing information, density index of stand was led into drowing control chart of stand density into variable-density yield table so that the outputting results between chart and. 引入林分密度指数，将林分密度控制图导成可变密度收获表，保证了图表之间输出结果的一致性，为可变密度收获表的编制提供了一种方法。
We will never yield to invaders. 我们绝不会向侵略者屈服。
