The effect of Ge Fe slag with Fe:Ge = 100~180:1 on the Ge enrichment on the process of neuter leaching Ge containing dust is studied The results show that the Ge enrichment ratio can reach 85% and reduce secondary Fe pollution due to exclude adding FeSO 4 on the following conditions: Ge Fe slag :waste solution :water = 4:5:2(volume ratio), MnO 2:10g/L slag, 50~60℃, 90min, pH:5 2~5 4

探讨了在烟化炉含Ge烟尘中性浸出时 ,加入Fe:Ge =10 0~ 180 :1的Ge -Fe渣对烟尘中的Ge再次富集的影响。结果表明在Ge Fe渣 :废液 :水 =4 :5:2 (体积比 )、MnO2 用量 :10g/L渣、50~ 6 0℃、90min、终点 pH :5 2~5 4等条件下 ,可使Ge的富集率达到 85%以上。在有效富集Ge的同时 ,排除了外加FeSO4引起的Fe二次污染

Metal poisoning which occurred in the RFCC unit has been analyzed with the emphasis on relations between feedstock and equilibrium catalyst Fe contents and catalytic cracking reaction result. Influence of catalyst Fe pollution on catalytic cracking reaction has been simulated and evaluated, and the results showed that catalytic cracking conversion rate and light oil yield have been decreased and slurry yield and catalyst consumption increased with the over high Fe content even though other...

Metal poisoning which occurred in the RFCC unit has been analyzed with the emphasis on relations between feedstock and equilibrium catalyst Fe contents and catalytic cracking reaction result. Influence of catalyst Fe pollution on catalytic cracking reaction has been simulated and evaluated, and the results showed that catalytic cracking conversion rate and light oil yield have been decreased and slurry yield and catalyst consumption increased with the over high Fe content even though other data are normal. In addition, influence of catalyst poisoning will be enlarged when the catalyst is polluted simultaneously with N, V, Ca and Fe.

对重油催化裂化装置催化剂出现的金属中毒现象进行了分析 ,重点对原料油和平衡催化剂的铁含量与催化裂化反应结果进行了探讨 ,并模拟评价了催化剂的铁污染对催化裂化反应的影响 ,证明铁含量过高时 ,即使平衡催化剂其它常规分析数据正常 ,仍会造成催化裂化转化率下降 ,油浆收率显著增加 ,轻质产品收率下降 ,催化剂消耗上升 ,镍、钒、钙与铁同时污染时 ,会加剧催化剂铁中毒的影响。

Aiming at solving those special problems in titanium equipment manufacturing (eg. hydrogen brittleness, cracks, Fe pollution, and etc.), the key links in industrial titanium trans-heat equipment manufacturing, that is welding of thin-wall tubes and tube-sheet (mainly about welding properties and main technical points),have been analyzed, according to pre-welding tests and engineering practice. In order to get satisfying result, some peculiar technical measures, such as full preparation of welding-spot, choosing of welding methods and facilities, adjusting and selecting of technical parameters, and so on, are adopted.

针对钛设备制造中的特殊问题(如易于产生氢脆、裂纹、铁污染等),结合焊前试验及工程实践,着重分析了工业纯钛换热器制作中的关键环节——薄壁管与管板的焊接(焊接特性与工艺要点)。通过采取一些有针对性的技术措施,如施焊场地的精心准备、焊接方法及设备的合理选用、工艺参数的调整筛选等,从而取得较为满意的效果。
