Technological Innovations in Photochemistry for Organic ...

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 ...

Biorefinery and Bioethanol Production. Fossil resources are still primary energy and chemical sources; around 75% is used for heat and energy production, about 20% as fuel, and just a few percent for the production of chemicals and materials ().Natural regeneration of fossil resources through the carbon cycle is significantly slower than their current rate of exploitation.

Highly conductive NiSe2 nanoparticle as a co-catalyst over ...

Designing a photocatalyst for hydrogen production is pivotal role in renewable energy technologies. Herein, the synthesis of nanosized NiSe 2 particles via supercritical fluid process with the short reaction time of 30 min was reported. Then, it was used as a co-catalyst over TiO 2 to improve H 2 production rate. Supercritical fluid process is an effective and alternative …

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].

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 …
