Consequently the slurry is often stirred to mix the solid and liquid components of the slurry prior to and during pumping of slurry from the pit. The customary form of slurry stirrer comprises a rotatable shaft mounted throughout its length within a fixed tubular housing, one end of the shaft being linkable to a power source such as a rotary ...

In response to this problem, this paper proposes a turbine-type stirred slurry pretreatment process to modify the surface of mc-Si wafers cut by diamond wire to make it suitable for the subsequent conventional wet acid texturing process. The experimental results show that the consistency of the surface structure of the mc-Si …

Among other things, it escapes during the storage of animal excrement, the slurry. A study by the University of Bonn now shows that methane emissions can be reduced by 99% through simple and ...

Diamond wire saw cutting multi-crystalline silicon (mc-Si) wafers has the advantage of high cutting rate. However, it is difficult to follow the current additive-free wet acid etching process to prepare the anti-reflective textured surface due to the obvious saw marks on the surface of the as-sawn wafer.

However, an important drawback of the slurry reactor is the separation of the catalyst from the waxes [16, 37, 108, 109, 112, 113].The catalyst for the slurry reactor is more susceptible to attrition.

The Fischer–Tropsch synthesis (FTS) was studied using mesoporous silica-supported bimetallic Co–Ni catalyst in a fixed-bed reactor (FBR) and a slurry continuously stirred tank reactor (CSTR) under different temperatures (from 280°C to 300°C) with syngas ratio of …

2.2.BT slurry preparation. The as-received BTO ceramic powders were dried at 100 °C for 12 h to avoid any water and CO 2 absorption. As for the self-formulated resin, U600, PPTTA, and HDDA were stirred at a 7:6:6 mass ratio at room temperature for 5 min and the 1 %wt TPO based on the total mass of the mixture was added to the resin.

The green parts formed by the PPMJ process contain a lot of organic substances such as resin and additives, so the debinding and sintering processes are required to obtain dense BTO parts after .

The computational model and results discussed in this work would be useful for extending the applications of CFD models for simulating large stirred slurry reactors. AB - A comprehensive computational fluid dynamics CFD model was developed in the present study to gain insight into the solid suspension in a stirred slurry reactor.

Mass transfer and reactivity experiments using two different slurry systems and two different Pd-catalysed reactions, i.e., oxidation of glucose (aqueous phase) and hydrogenation of a-methyl styrene (organic phase), with both hydrophobic carbon and hydrophilic silica catalyst supports, were performed in a laboratory scale surface aeration ...

First, the mixture of quicklime, fly ash and site soil with the designed mix proportion is stirred at a speed of 450 r/min for two minutes. Then, the binder is mixed and stirred at the same speed for one minute according to the designed liquid-solid ratio. Finally, the prepared slurry is poured into the mold to shape.

The effect of stirred slurry pretreatment on the surface uniformity of large-size mc-Si wafers was further studied by simulation analysis. The research results show that the appropriate process parameters can achieve uniform pretreatment of the wafer surface when pretreatment of large-size mc-Si wafers for industrial applications with stirred ...
