应用煤岩相方法并结合化学和工艺性质分析对峰峰煤田煤进行了比较系统的鉴定.本煤田系属于石炭-二叠纪,煤的变质程度沿走向由南向北加深.煤层宏观岩相以暗色和暗色层状煤为主,其微观煤岩成分则大部为镜煤.显微镜研究表明,煤层呈现暗色系由于其中存在许多细小夹石层以及煤岩成分受矿物质浸染之故.同时观察到,角质类物质含量有沿走向逐渐减少的趋势,说明其含量的多少是变质变化的结果,而不决定于原始物料.峰峰煤田煤的可选性一般较差,这和煤岩成分被细条与粒状矿物浸染有关,并且也和煤层中夹石层的多寡相适应.根据煤的工艺性质,峰峰煤田煤一般皆属于好的炼焦煤.

The excitation functions of the ~(23)Na(p,α_0)~(20)Ne_(g·s).and the ~(23)Na(p,α_1)~(20)Ne_(?) reae-tion have been measured from E_p=1 to 2.5 MeV at θ_L=30°,150° and 30°,respectively.Around the resonance at 2.171 MeV,the excitation functions of the(p,α_0)reactionhave been measured at 12 angles,then,some angular distributions have been obtainedfrom these excitation functions.In addition,the angular distribution of the(p,α_0)reaction for the resonance at 2.171 MeV has also been measured directly at energy ofthe resonance peak of the excitation function at 150°.For the resonance at 2.117MeV,the angular distribution have been measured at two energies,one at the energyof the resonance peak of the excitation function at 150°,another at the energy of thehalf maximum point of the resonance peak on the higher energy side.Around the re-sonance at 2.075 MeV,the excitation functions have been measured at 16 angles,andthe angular distribution has been obtained from three excitation functions.The an-gular distributions of the three resonances are not symmetric about 90°,and the posi-tions of the resonance peaks of these resonances varies with the angle of measurement.By means of the compound nucleus theory,discussions have been made for these non-solated resonances.

本工作测量了~(23)Na(p,α_0)~(20)Ne_(g.s).反应在 E_p=1—2.5MeV 能量范围内和θ_L=30°,150°时的激发函数,还测量了~(23)Na(p,α_1)~(20)Ne_(lst),反应在上述能量范围内和θ_L=30°时的激发函数.对2.171 MeV 共振,在12个角度上测量了(p,α_0)的激发函数,并由激发函数求得了多个角分布,另外在一个固定能量上(150°激发函数的共振峰上)测量了(p,α_0)反应的角分布.对2.117 MeV 共振,在二个固定能量上(150°激发函数的共振峰上和其高能端的半高点处)测量了(p,α_0)反应的角分布.对2.075 MeV 共振,在16个角度上测量了(p,α_0)反应的激发函数,并由激发函数求得了角分布.这三个共振的角分布不是90°对称的,并且共振峰的峰位与角度有关.用复合核理论对它们进行了讨论.

Studies of the surface acidity of zeolites have been made under conditions close to the reaction conditions by TPD technique. Two TPD peaks of desorbed pyridine were found on NaY zeolite. The peak I is considered to be the principal peak, before it the peak 1 is a shoulder, the former is regarded as species of pyridine adsorbed on Na+ ion in the supercage, the latter may be resulted from physically adsorbed pyridine(in the supercage).As the exchange-percentage of Ca2+ ion is increased to about 40-60%, a new desorption peak III appears in the high temperature range, and at the same time the shoulder peak I gradually disappears.The products desorbed from the zeolites were identified by chromatogra-phic analysis, only pyridine is detected. The total amount of adsorbed pyridine gradually decreases as the amount of Ca2+ ion in the zeolite is increased. This indicates that the pyridine is adsorbed on Na+ ion very strongly. Consequently, for any alumina-silicate sample with high Na+ content, its surface acidity cannot be simply expressed by the total amount of pyridine adsorbed.

用程序升温脱附技术,在接近反应条件下研究沸石的表面酸性。在NaY沸石上吡啶的程脱峰有二,峰Ⅱ为主峰,其前沿有一肩膀峰Ⅰ,前者为吡啶吸附于Na~+上的物种,后者可能为残留的物理吸附吡啶(在超笼中)。随Ca~(2+)离子交换度的增加,在交换度40—60%间程脱峰谱发生质的变化,在高温区另出现一脱附峰(峰Ⅲ),与此同时峰Ⅱ向低温迁移,峰Ⅰ渐趋消失。经色谱鉴定,脱附产品中只有吡啶存在,其总吸附量随Ca~(2+)交换度增加而递减,表明吡啶分子在Na~+上的吸附极为显著,因此对Na~+含量甚高的硅铝样品,不能采用吡啶的总吸附量来作为酸性数量的衡量标准。
