Another reactor design that incorporates thin film generation is the rotating film reactor, introduced by Knig et al. This reactor consists of a rotating glass vial irradiated by 4 blue LEDs (455 nm, 28.1 mWcm –2) placed on an aluminum frame around the vial (Figure 14C). The reactor was operated in batch mode by rotating the vial with a ...

Feb 22, 2022 Hydrogenations and hydrodeoxygenations represent two of the most important reactions in the production of both bulk and fine chemicals. Despite the wide and long use of metal-based catalysts for this reaction, there is still some uncertainty with respect to the properties governing the catalyst activity. Using the hydrogenation of benzaldehyde as a model reaction, …

However, solvents need to be drained from the reactor, evaporated, condensed and recycled, which makes the pretreatment costs relatively high. Organosolv extraction of sugarcane bagasse under optimized conditions (30% by volume ethanol at 195 C for 60 min) results in the production of 29.1% by mass of fermentable sugars .

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 …

Oct 15, 2019 The H 2 and CO mixed gas then enters the FT reactor to create a FT synthesis. The main reactions during the FT are CO and H 2 reacted to generated C n H 2n O 2, C n H 2n O, C n H 2n+2 O, C n H 2n+2 and C n H 2n. Unconverted syngas and some FT gas could recycle to the FT reactor after a reforming. The liquid products should be refined to get ...
