as the coke burns, some of it combine with the oxygen in the air to form carbon monoxide 焦碳燃烧时,一部分碳与热风中的氧形成一氧化碳。

due to reducing coke burning amount at high catalyst flux, packing stripper was fit for oil becoming heavier and olefin producing via fcc 填料型汽提器在高催化剂循环通量条件下仍可有效降低再生器烧焦量,正适合原油重质化和利用催化裂化生产低碳烯烃的发展趋势。
concerning sulfur deposition, the carbonaceous matter deposition and the sulfuric acid salinization due to exterior factors, the measures such as sulfur removal, coke burning and reduction operation can be taken to prolong the service life of the catalyst 对于因外部因素硫沉积、含碳物质沉积和硫酸盐化原因引起的催化剂活性衰退可分别采取除硫、烧炭和还原操作方法恢复其活性,延长催化剂的使用寿命。
discussing these and kindred topics they made a beeline across the back of the customhouse and passed under the loop line bridge when a brazier of coke burning in front of a sentrybox, or something like one, attracted their rather lagging footsteps 他们扯着诸如此类的话题,抄近路打海关后面走过,并从环行线的陆桥下穿行。这时,岗亭或类似的所在前燃着一盆焦炭,把正拖着颇为沉重的脚步走着的他们吸引住了。
