IFP连续重整新一代催化剂再生技术的改进

介绍了我国引进的采用法国石油研究院 (IFP)三代催化剂连续再生技术的重整装置 ,分析了第二、第三代技术在原有基础上的改进 ,从再生气循环回路、再生操作参数和再生器内部结构三个方面重点介绍了第三代催化剂连续再生技术的特点和优势 :使催化剂的烧焦气循环回路与氧氯化用气、焙烧气循环回路彼此分开 ,烧焦、氧氯化、焙烧的操作参数可分别得到优化 ,使氧氯化及焙烧在高氧条件下进行 ,有利于催化剂金属的再分散 ,保持催化剂的活性。     

攀钢转炉炼钢用碳化硅提温的试验研究

低品位碳化硅是转炉炼钢的有效提高温剂。工业性试验结果表明，碳化硅加入８．０ｋｇ／ｔ钢水提温４０．３－７０．３℃（平均４８．４℃）；渣中ＴＦｅ降低１．３％；加提温剂有利于转炉内造渣脱硫和碱少炉渣对耐火砖的侵蚀。文中还给出了攀钢转炉半钢冶炼铸用钢不水时加与不加碳化硅的ｔλ，［Ｃ］λ区域。     

3961连续重整催化剂性能考察

新一代高活性，高水热稳定性3961（PS－Ⅳ）型连续重整催化剂于1996年在上海石化芳烃厂400kt/a连续重整装置上首次进行工业应用试验。开工5a，催化剂跟踪分析结果表明，该剂保持了良好的物化性质和反应性能，表现为良好的比表面积稳定性和持氯能力，经过200个以上再生周期的催化剂未发现有明显的相变和金属分散度的变化。

Electricity generation from rice husk in Indian rice mills: Potential and financial viability

Rice husk generated as a by-product of rice processing is an important energy resource. The availability of this resource in India has been assessed and the technologies for exploitation of its energy potential in rice processing industry discussed. Nomographs have been developed for estimation of the husk required to meet the energy demand of parboiling, drying and milling operations. The unit cost of electricity using rice husk gasifier-based power generation systems has been calculated and its financial feasibility assessed in comparison with utility-supplied and diesel-generated electricity. With the cost and efficiency data assumed here, the unit cost of electricity produced by rice husk gasifier-dual fuel engine-generator system varies between Rs 2/kWh and Rs 7/kWh. (Note: 35 Rs approximates to $US 1.)

适用于稠油开采的游梁式抽油机设计分析

在稠油开采中,抽油杆在液体中运动时,所受到的摩擦阻尼力很大,有时高达几十千牛。上冲程时,该力有加大悬点载荷的作用;下冲程时,该力使抽油杆下行困难,甚至悬点载荷为零。为了开采稠油,必须根据其特点设计适应的游梁式抽油机。文章分析了稠油用抽油机的受力特点,提出了该类抽油机的设计要求。

In situ regeneration of the Ni-based catalytic reformer of a 5 kW PEMFC system

The paper reports the results of on-site regeneration catalytic bed of the natural gas reformer in a 5 kW PEM fuel cell system. The Ni catalyst previously poisoned by sulphur from the available natural gas, could be re-activated by injection of pure water steam, following the method developed for industrial reformers using the same metal catalyst: this method was shown to be perfectly efficient, provided no natural gas was fed during the operation. Results of the tests conducted are presented and discussed in relation to published data on S-sorption on Ni surfaces.
