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 ...
Get DetailsApr 07, 2012 The reactor was a stainless steel having dimensions of 1 in. OD 8 in. height with 0.083 in. wall thickness. Both ends of the reactor were welded to a in. OD stainless steel tubing. Glass beads (2 mm diameter) were used to fill up the in. tubing and reducer weld fitting at the bottom of the reactor.
Get DetailsBiorefinery 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.
Get DetailsDesigning 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 …
Get DetailsFeb 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, …

Biofine process is a good example of advances in furfural production, ... reductive amination to amines, reduction to alcohols, decarboxylation, oxidation to carboxylic acids, Grignard reactions and aldol and Knoevenagel condensation can occur in furfural through the aldehyde functional group.
Get DetailsJan 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].

Get DetailsMany 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 …
Get DetailsOct 15, 2016 This reactor consists of a mixture of two phases, the solid and the liquid and usually accomplished by passing a pressurized fluid through the solid material. It is very popular for fast pyrolysis as it has the following advantages : The provision of heat transfer is rapid. It has a good grip of pyrolysis reaction and vapour holding time control.
