Analysis of Fluid-Solid Reaction in Fixed-Bed Reactors under Isothermal Conditions

Synthesis of Biodiesel in Microstructured Reactors under Supercritical Reaction Conditions

At IMM the advantages of an alternative synthesis route for biodiesel under supercritical conditions in micro-structured reactors applying heterogeneous catalysts are currently under investigation. Target of the development work is to build a pilot plant with an annual production capacity of 40 t which covers all process engineering steps and verifies their functionality in laboratory and field...

Modeling of Non-isothermal Reacting Flow in Fluidized Bed Reactors

Abstract: We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture of CO2 and H2 in the presence of microscopic floating solid catalytic particles. We describe the sys...

Study on Pebble-Fluid Interaction Effect in Pebble Bed Reactors

INTRODUCTION In pebble bed reactors (PBRs), fuel pebbles containing TRISO particles continuously circulate within the core during operation, while the coolant fluid, either helium gas (in Pebble Bed Gas-cooled Reactors) or molten flibe salt (in Pebble Bed-Advanced High Temperature Reactors), continuously passes through the pebbles to transfer the heat generated by fission reactions out of the c...

Absorption accompanied with chemical reaction in trickle-bed reactors

Abstraet---A new development in the field of internals in packed columns is the use of structured packing types. Recently, a new structured packing type coated with a thin alumina layer (KATAPAK rM) has been developed, in this report, the results of an experimental and theoretical study concerning the possible applicability of this new packing material for hydrogenation processes in a trickle-b...
