Special Issue Information

Dear Colleagues,

In recent years, the demand for pure hydrogen has increased owing to its important role as a clean energy carrier. Membrane technology seems a promising technology for hydrogen production and purification. On the one hand, novel reactor concepts are being developed for efficient (high purity) hydrogen production. Among them, the membrane reactor is an interesting alternative to conventional multi-stage processes. In this reactor, chemical reactions and hydrogen separation using membranes take place in the same unit, thus achieving an important process integration which results in a reduction in the required number of process units and providing similar conversions but at lower temperatures compared to the conventional reactors.

On the other hand, H2 can be distributed and blended with natural gas through the existing gas grid infrastructure. Once reaching the end user, high purity H2 can be extracted from the admixture by using membrane technology.

In addition, there is a recent interest in transporting hydrogen as a liquid hydrogen carrier (i.e. ammonia, methanol, liquid organic hydrogen carriers) from locations with high renewable energy potential to locations demanding energy. Membrane technology can be used to efficiently convert the hydrogen carriers back to hydrogen at the point of use.

The aim of this Special issue is to present the recent advances in membrane technology for hydrogen production and hydrogen purification within the overall hydrogen value chain. Topics include, but are not limited to, types of membranes (i.e., metallic, carbon, ceramic, polymeric), manufacturing techniques, module and reactor design, membrane reactors, novel applications, and demonstration efforts and industrial exploitation. Authors are invited to submit their latest results; both original papers and reviews are welcome.

In petroleum refineries, naphtha reforming units produce reformate streams and as a by-product, hydrogen (H2). Naphtha reforming units traditionally deployed are designed as packed bed reactors (PBR). However, they are restrained by a high-pressure drop, diffusion limitations in the catalyst, and radial and axial gradients of temperature and concentration. A new design using the fluidized bed reactor (FBR) surpasses the issues of the PBR, whereby the incorporation of the membrane can improve the yield of products by selectively removing hydrogen from the reaction side. In this work, a sequential modular simulation (SMS) approach is adopted to simulate the hydrodynamics of a fluidized bed membrane reactor (FBMR) for catalytic reforming of naphtha in Aspen Plus. The reformer reactor is divided into five sections of plug flow reactors and a continuous stirrer tank reactor with the membrane module to simulate the overall FBMR. Similarly, a fluidized bed reactor (FBR), without membrane permeation phenomenon, is also modelled in the Aspen Plus environment for a comparative study with FBMR. In FBMR, the continuous elimination of permeated hydrogen enhanced the production of aromatics compound in the reformate stream. Moreover, the exergy and economic analyses were carried out for both FBR and FBMR. Full article
