Continuous hydrogenation using ACMC-Pd monolith catalysts was studied for four chemistries of industrial interest. The chemistry was run in a 30.5 cm catalyst bed with repeated passes to simulate a longer commercial catalyst bed in which >97% conversion would be completed in a single pass of the reactor with no recycle. The selected liquid flow rate (0.086 cm/s) enabled >97% conversion for the four chemistries using practical ranges of temperature (60–180 °C), pressure (0.348 to 3.48 MPa), and required bed lengths (4.3 to 6.1 m). The unsaturated bonds hydrogenated included nitro, carbonyl, olefin, and aromatic bond types. The most challenging reaction was the conversion of a neat olefinic/aromatic substrate (requiring 7 moles of hydrogen per mole of product) run with a low-temperature/high-temperature reactor configuration. The same catalyst was used for all of the chemistries, and the changeover from one chemistry to another involved simple solvent/substrate rinses of the reactor. The data can be used to estimate the number of commercial reactor tubes, temperature, pressure, and bed length needed for the production of commercial quantities of specialty and pharmaceutical chemicals.

“…Hence, when particle size was less than 150 mm and agitation speed was 550 rpm, the effects of internal and external diffusion were deemed to be negligible. As for the kinetics model, Pandit et al, 43 Milian et al, 44 and Yu et al 45 have reported that the hydrogenation of nitrobenzene is a rst-order reaction, which could be expressed in the form of −ln(1 − X) = kt that tted our system. In order to obtain intrinsic kinetic data, the hydrogenation of nitro group was carried out under 20, 30, 40, and 50 °C, respectively.…”

Catalytic processes are indeed greener modification as they completes in much shorter time with minimizing the need of external energy source with atom economy and high selectivity. In this article we presented a short review on utlisation of different catalysts such as ionic liquids, transition metal ions, nano particles, surfactants, amino acids etc. for C‐C coupling reactions to oxidation reactions. Stereoselective and regioselective transformations are also carried out using catalyst in organic synthesis. Use of catalyst in rate enhancement of oxidation reaction is of immense interest and a surplus rate increment is obtained by use of promoters.
