炼焦过程利用含锌粉尘实现高温焦炉煤气脱硫的实验与模拟

提出了在炼焦过程中利用含锌粉尘作为焦煤添加剂，从而实现高温焦炉煤气脱硫的设想.热力学模拟计算和实验表明，在炼焦前期，含锌粉尘是非常有效的缚硫剂. 而在炼焦后期，在炼焦室中锌呈气态从半焦中进入焦炉煤气，在焦炉煤气离开炼焦室后，气态锌与硫化氢反应生成固态硫化锌. 脱硫产物自动从焦炉煤气中分离出来，从而实现了焦炉煤气的脱硫. 锌在焦炭中残留极少；氧化铁的存在有助于炼焦后期半焦中锌的挥发；含锌粉尘对焦炭质量的影响很小.     

重量法和红外法测定外排水石油类物质的比较

针对锦州市环保监测站分析锦州石化公司外排水中石油类物质采用重量法,而公司环保监测站采用红外光度法引起的数据差异争端,对两种分析方法进行了对比.结论为重量法灵敏度低不适合分析含油低的外排水样,而红外法灵敏度高,分析含油低的外排水方法可靠、数据合理.建议外排水样采用红外光度法.     

Selectivity effects of a new aluminum species in strongly dealuminated USY containing FCC catalysts

We have hydrothermally prepared and characterized a catalytically active tetrahedral aluminum species in faujasite distinct from the normal framework aluminum. The new tetrahedral species is formed after a severe steam dealummation at 830°C and is characterized by a²⁷A1 MASNMR shift of about 53 ppm compared to the 60 ppm shift observed for framework tetrahedral aluminum. DRIFTS experiments show that the 53 ppm species is associated with a Lewis rather than a protonic site. This species is associated with strong acidity and poor cracking selectivity compared to a conventional dealuminated faujasite at the same unit cell size. This site is very active and makes large amounts of gas and coke with poor gasoline selectivity compared to typical commercial FCC catalysts. After an appropriate sequence of hydrothermal dealumination and controlled pH washing steps, the 53 ppm species is the only species observed by NMR.

高炉用焦炭热强度指标要求及检测方法

高炉冶炼通常要求焦炭具有较低的反应性和较高的反应后强度．但焦炭反应性过低不利于提高高炉反应效率．本文对焦炭在高炉内消耗机理进行了分析,认为高炉炉身焦炭消耗量与铁矿石直接还原度相关,炉身消耗的焦炭量是比较稳定的,现有焦炭热强度评价方法存在不足．为了避免焦炭反应过度,应调整焦炭热强度指标的测定方法,如改变反应气氛或根据焦炭失重量确定反应时间,使测定结果能够合理反映炉内焦炭消耗的规律．
