Although nitriding provides us with an iron catalyst of good durability and resistance to carbon deposition,it brings at the same time a higher methane form- ation during synthesis,this has hindered its application in industry. Accordingly,factors effecting this main side-reaction were thoroughly studied. They are:reaction temperature and pressure,space velocity,particle size of catalyst, alkaline content in catalyst,method of reduction,degree of nitriding,and aging of catalyst.With the exception of space velocity,all...

Although nitriding provides us with an iron catalyst of good durability and resistance to carbon deposition,it brings at the same time a higher methane form- ation during synthesis,this has hindered its application in industry. Accordingly,factors effecting this main side-reaction were thoroughly studied. They are:reaction temperature and pressure,space velocity,particle size of catalyst, alkaline content in catalyst,method of reduction,degree of nitriding,and aging of catalyst.With the exception of space velocity,all of these independent variables play quite important roles iu effecting the yield of methane.The relative impor- tance of these variables are discussed in detail.Among them,the alkaline content and operation pressure are the most influential.With the increase of the alkaline content from 0.8 to 1.7g K_2O/100g Fe (by impregnation),methane formation can be effectively depressed,for example,at 7 atm.and 15 atm.,CO converted to methane is reduced from 7-9% to 5-6% and from 5-7% to 3% respectively.Further- more,the tendency of increase in methane formation with time can also be checked by addition of alkaline. The product distribution has been correlated with methane formation by sum- marizing data reported in literatures and our own results.Presumably methane is essentially formed on some special locations on the catalyst.However,the operation conditions which favor the formation of light hydrocarbons always enhance the for- mation of methane at the same time,so that there appears some parallelism between them. The mechanism of methane formation and the reason for its steady increase in life tests are also discussed.

在已经解决了氮化熔铁催化剂的活性维持问题及原料气体合理利用的基础上,进一步研究了合成时的一个主要副反应——CH_4的生成——与各项操作变数的关系.确定了反应温度、压力、空间流速、催化剂粒度、催化剂的酸含量、还原方法、氮化度及催化剂的存放时间等独立变数对 CH_4生成率的影响,指出应用浸渍法适当增加催化剂的碱含量并采用较高的反应压力(15气压左右)可以抑制 CH_4的生成率到已转化的 CO 的3%左右.以上措施对和缓 CH_4生成随时间增加的趋势也有良好的影响.综合实验结果,论证了 CH_4生成率与产品轻重间的依附关系,并对 CH_4生成的原因及其随合成时间而逐渐增加的现象作了初步理论上的探讨.

The formation potency of lipid peroxidation induced by NADPH, NADPH+ ADP-Fe3+ or NADPH + ADP-Fe3+ + EDTA-Fe3+ in rat liver microsomes and the dependence of malonaldehyde values on the storage times of microsomes were determined.The effects of twelve cations, T1+, Mg2+, Ca2 + , Mn2+, Ni2+, Cd2+, La3+, Ce3+, Pr3+, Nd3+, Eu3+ and Ce4+ on lipid peroxidation in the NADPH and NADPH + ADP-Fe3+ stimulation systems were studied respectively. Mn2+, Ce4+ and Ce3+ ions showed very potent inhibition of lipid peroxidation, and Ca2+, Cd2+ and Eu3+ ions had slight inhibition, whereas Mg2+ ion could stimulate lipid peroxidation. The influences due to cations in the simple NADPH system were generally greater than that in the NADPH + ADP-Fe3+ System.However, the respective effects of three anions SeO32-,GeO32- and AsO33- on lipid peroxidation were not obviously observed.

测定了NADPH、NADPH+ADP-Fe~(3+)或NADPH+ADP-Fe~(3+)+EDTA-Fe~(3+)诱发体系,对大鼠肝微粒体形成脂质过氧化的能力,以及微粒体存放时间对MDA(丙二醛)值的影响。 观察了Tl~+、Mg~(2+)、Ca~(2+)、Mn~(2+)、Ni~(2+)、Cd~(2+)、La~(2+)、Ce~(3+)、Pr~(3+)、Nd~(3+)、Eu~(3+)及Ce~(4+)等12种阳离子,在NADPH或NADPH+ADP-Fe~(3+)诱发体系中,对脂质过氧化的影响。Mn~(2+)、Ce~(4+)、Ce~(3+)离子对脂质过氧化具有强的抑止作用,Ca~(2+)、Cd~(2+)、Eu~(3+)离子有轻度抑止作用。Mg~(2+)离子,则促进脂质过氧化。阳离子在NADPH诱发体系中的影响,普遍比在NADPH+ADP-Fe~(3+)体系中的影响要大。 另外,在NADPH+ADP-Fe~(3+)诱发体系中,SeO_3~(2-)、GeO_3~(2-)、AsO_3~(3-)三种阴离子,对脂质过氧化均无显著的作用。
