Hydrothermal vents and the origins of life Feature ...

Apr 16, 2017 Lane’s simple bench-top, open-flow origins of life reactor 4 is simulating hydrothermal vent conditions. On one side of a semiconducting iron–nickel–sulfur catalytic barrier, an alkaline fluid is pumped through to simulate vent fluids and on the other side, an acidic solution that simulates sea water.

Feb 19, 2022 Wang et al. used the SDBD reactor to eliminate the P123 copolymer from SBA-15. The FT-IR spectra of as-synthesis SBA-15, SBA-15-C, and SBA-15-DBD are illustrated in Figure 10(b). Normally, the aliphatic stretching and bending vibrations are observed at wavenumbers between 2950 and 2840 cm –1 and 1500–1350 cm –1, respectively.

Lactic acid production to purification: A review - NCSU

Fig. 2. Overview of the two manufacturing methods of lactic acid, chemical synthesis and microbial fermentation (Wee et al. 2006) Chemical Synthesis. Lactic acid production by chemical synthesis using the lactonitrile route, which was a by-product of acrylonitrile technology, was discovered in 1863 by Wislicenus (Benninga 1990).

Hydrothermal Carbonization: Upgrading Waste Biomass to ...

Jan 11, 2021 Hydrothermal carbonization (HTC) is a thermochemical conversion process that uses heat to convert wet biomass feedstocks to hydrochar. HTC is performed in a reactor at temperatures ranging from 356 to 482F, i.e., 180 to 250C, under autogenous (automatically generated) pressure, with feedstock residence time ranging from 0.5 to 8 hours [1,2].

Scale-Up of a Heterogeneous Photocatalytic Degradation ...

Many chemical reactions contain heterogeneous reagents, products, byproducts, or catalysts, making their transposition from batch to continuous-flow processing challenging. Herein, we report the use of a photochemical rotor–stator spinning disk reactor (pRS-SDR) that can handle and scale solid-containing photochemical reaction conditions in flow. Its ability to handle slurries …

They synthesized the support material using two different methods, the solid phase reaction method and the hydrothermal method. [7, 96] The temperature at which water and hydroxyl groups were removed during the hydrothermal synthesis was varied between 873 and 1273 K to find out how this affected the surface area and catalytic performance.
