小型流化床实验台上镍基载氧体的积炭特性

采用小型流化床反应器,研究了Ni基载氧体在不同还原气氛（CH4、CO+H2）和不同反应温度（650 ℃、750 ℃、850 ℃、950 ℃）下的反应特性。结果表明：Ni基载氧体在两种气氛下均表现出较高的反应活性,CO+H2气氛下的还原反应比CH4气氛下的还原反应更完全,两个还原过程中均有积炭的产生,CH4气氛下的积炭比CO+H2气氛下的积炭更为严重;在CH4气氛下,温度的升高有利于Ni基载氧体还原反应的进行,同时还原过程中产生的积炭量也随着温度的升高有所增加,但当温度升高到850 ℃后,温度的增加对还原反应的影响不大。另外,相比于Cu基载氧体,Ni基载氧体虽然有更好的反应活性,但在还原过程中更容易产生积炭。     

Role of TiO2 nanoparticles in the dry deposition of NiO micro-sized particles at room temperature

A room-temperature dry-deposition method with TiO₂ powder was used to deposit NiO particles onto a fluorine-doped tin oxide (FTO) substrate. Initially, in the absence of TiO₂ powder, we observed that the NiO particles did not adhere to the substrate; however, the addition of TiO₂ particles facilitated NiO deposition. The volume percentage (vol%) deposition of NiO particles increased with the TiO₂ particle concentration. The inability of the NiO particles to adhere to the FTO substrate was attributed to the absence of deformation and fragmentation in the substrate. This is related to the lower hardness of the FTO substrate, compared with that of the NiO particles. However, the addition of the TiO₂ particles at different vol% during NiO deposition induced deposition, possibly due to the lower hardness of the TiO₂ particles compared with the FTO substrate. The minimum TiO₂ fraction that enabled NiO powder deposition was ~4.8 vol%. Microstructural analysis revealed that TiO₂ powder agglomerates tended to break up as the NiO particles impacted the substrate surface, creating a “deposition complement” from the excess kinetic energy. The deposition mechanism was investigated using microstructural analysis, electron probe microanalysis, and Brunauer–Emmett–Teller (BET) measurements; the results confirmed the influence of the TiO₂ powders on NiO powder deposition, specifically, an improvement in the adhesion and density of the NiO powder and a decrease in the surface roughness of the coating. Therefore, we demonstrated NiO deposition with TiO₂ particles at room temperature, providing potential applications to the supercapacitor and battery industries.

The mechanism of the deposition of pyrolytic carbons

The changes in crystallite-preferred orientation, distribution of 0.1–1.0-μm diameter pores, density, growth feature shape, and crystallite arrangement that occur with changes in the conditions of pyrolytic carbon deposition in a fluidized bed of particles are studied. Based on these changes a deposition mechanism is proposed wherein changes in the crystallite-preferred orientation and the pore distribution are controlled by the relative concentrations of two depositing components, which are solid particles and molecular species. Changes in the crystallite arrangement, and thereby the density, are controlled by changes in the reaction probability of the planar hydrocarbon molecules with the carbon surface.     

The mechanism of the controlled deposition of electrospun fibers

The controlled deposition of electrospun fibers means that the electrospun fibers can be collected in a limited and specified area and can present better applications in the fields of medical treatment, garment making, and 3D printing. In order to study the mechanism of the controlled deposition of electrospun fibers, simulation and experimental methods were used. Specifically, in the electrospinning experiment, circular copper sheets of different diameters were used as collectors. The effect of different collector areas on the morphology of fiber deposition was discussed. The electric field distribution of electrospinning with different specifications of collectors was simulated correspondingly. The experimental results show that, as compared to the traditional large flat collector, the area where the electrospun fibers are deposited is significantly reduced when a smaller circular copper plate was used as a collector. The smaller the area of the collector, the more the fibers tend to deposit at the center area of the collector, and the more likely the morphology of the product formed by the fiber deposition to exhibit a center protrusion shape. The controlled deposition of the electrospun fiber technology can provide more opportunities for the application of the electrospinning technology.     

长岭断陷登娄库组天然气成因类型分析

天然气成因类型判识是整个天然气成藏研究的核心内容之一。本文利用天然气组分特征、碳同位素特征等测试资料,对长岭断陷登娄库组天然气的成因类型进行了综合判断。长岭断陷深层（K 1yc＋K 1d）天然气以来自营城组和沙河子组的高-过成熟煤型气为主,并混有部分油型气,不同成因类型天然气的混合导致碳同位素系列的倒转。此外,少数构造可见纯度较高的幔源二氧化碳气藏。因此,综合天然气的地化特征及该区的石油地质条件判断,长岭断陷登娄库组天然气既有有机成因气,也不排除无机成因的可能。
