TL;DR: In this paper, the results of an experimental and theoretical study concerning the possible applicability of a new packing material for hydrogenation processes in a trickle-bed reactor is presented. But the results show that the application of KATAPAKTM does not significantly improve the overall performance of the cascade.

TL;DR: In this article, a packed-bed micro-reactor was used for the hydrogenation of o-nitroanisole to o-anisidine in a pharmaceutical and fine chemicals industry with the aim of investigating the reactor performance and kinetics of the reaction.

Journal ArticleDOI
TL;DR: In this article, the authors discuss the process intensification by operating at elevated pressure and temperature, and better understanding of flow behavior (which also helps for better design and scaleup), inducing pulse and operating in countercurrent mode.

Journal ArticleDOI
TL;DR: In this article, an analogy between the flow patterns in real separation columns equipped with structured packing and film flow is used to develop a new modelling approach. The packing is represented as a bundle of channels with identical triangular cross section, and dimensions of the channels as well as their number are derived from the packing geometry.

TL;DR: The design and scale-up of a TBR is still not well understood, especially with respect to hydrodynamic parameters as discussed by the authors, and there are very limited studies available in literature for the design and scaling up of the TBR.
Abstract: The importance of hydroprocessing has been accelerated due to the imposition of stringent environmental regulations on petroleum products to achieve future goals of sustainability and cleaner environment, and the more demanding situation of middle distillates (mainly transportation fuels) against the availability of heavier and high sulfur crudes. Trickle-bed reactors (TBRs) are mostly used in hydroprocessing. Other types of reactors, such as moving bed reactors and ebullated-bed reactors (EBRs) are also used in the hydroprocessing. All of the above mentioned reactors are operated with cocurrent up or downflow of gas and liquid. TBRs have been most commonly studied over the last 30 years. The design and scale up of TBR is still not well understood, especially with respect to hydrodynamic parameters. Though the EBRs are gaining importance because of their flexibility in dealing with most types of heavy feedstock and the ease with catalyst replacement during operation, there are very limited studies available in literature for the design and scale up of the reactor. Recently, countercurrent operation in a structured catalytic packed bed is gaining importance for hydroprocessing in order to obtain higher conversions. The structured packed column, in which the catalyst particles are enclosed within
