| | A porous ceramic honeycomb is coated with active Al2O3, On this ceramic honeycomb several active ingredients are supported forming a multicomponent catalyst with the composition of La, Ba, Cu, Ni, Mn and trace of Pd. The activity of this catalyst has been tested in the laboratory and by the engine stand. The conversions of CO and HC by using of engine stand are 90% and 80% respectively, and at souitable condition of A/F ratio the catalysts can reduce CO, HC and NOx simultaneously. | | 由多孔陶瓷制成蜂窝体,再浸上活性氧化铝。用此蜂窝状载体制成多组分催化剂,其活性组分为La,Ba,Cu,Ni,Mn以及微量的Pd。对该催化剂进行了实验室及台架试验。通过台架试验,对CO,HC的净化率分别为90%和80%,在适当的空燃比条件下,可以同时净化CO、HC和NOx。 | | 文摘来源 | | A new method of determination of dissolved oxygen in seawater using oxygen electrode without a membrane has been made. Differing from Clark cell, a new model for dissolve cxygen probe has been designed with the following features:( 1 ) Without a gaseous diffusion semi-permeable membrane.( 2 ) Provided with two gold cathode electrodes (a disc and a ring) anda ring anion exchange membrane. ( 3 ) Autometic inlet of sample water into the probe not interfered by air.By means or this modificatitn, the stability o... | | 本文叙述了用脱膜氧电极—恒电位时安法测定海水溶解氧的步骤及影响因素等。此法有快速(一个水样/分)、准确(±1%)的特点,可用于海洋调查船实验室。 | | 文摘来源 | | The distillation-nitration method is a new process for nitrating toluenc toTNT. This process utilizing modern efficient wire gauze wave-like packings sepa-rates three isomers of MNT(ortho-.meta- or para-), then the O-MNT or P-MNTis nitrated to produce military TNT by a mixture of nitric and sulfuric acid. Thepurification process can be omitted which involves the treatment of the crudeTNT by aqueous sodium bisulfite solution. There are three purposes ofdistillation-nitration method, namely: a) To get rid of ... | | 精馏-硝化法是把甲苯硝化成TNT的一种新工艺。 本工艺利用近代高效的金属丝网波纹填料分离MNT的三种异构体(邻一、间一、对一),然后用硝硫混酸把邻一或对一MNT硝化成军品TNT,这样可避免亚硫酸钠溶液精制TNT的工序。精馏-硝化法有三个目的: (a)消除红水(它是一种精制工序产生的污染物)。 (b)MNT多种多样的利用。 (c)军民结合。 本报告研究了关于MNT—DNT精馏分离中的安全问题。藉助于精馏操作基本原理及高效的金属丝网波纹填料的低阻力可设计一套分离装置。通过实验室的试验和在9395厂中间试验的发现,DNT在塔釜中的浓度可以突破美国专利3620928[1]提出的爆炸极限值(10%),即MNT-DNT的分离工艺是安全的。结果为精馏-硝化法扫除了技术上的障碍。 | | 文摘来源 | |   | | << 更多相关文摘 |
