Hydrogel coated monoliths for enzymatic hydrolysis of penicillin G

The objective of this work was to develop a hydrogel-coated monolith for the entrapment of penicillin G acylase (E. coli, PGA). After screening of different hydrogels, chitosan was chosen as the carrier material for the preparation of monolithic biocatalysts. This protocol leads to active immobilized biocatalysts for the enzymatic hydrolysis of...

Development of a monolithic bioreactor: Design and application

Recently, biocatalysis has become an interesting alternative for conventional industrial processes. Enzyme reactions are highly selective and fast, and can be performed under ambient conditions. A drawback of the use of enzymes is their fragile nature. Stirring, high temperature, or solvents can cause deactivation. Also separation of the free...

Oxidative dehydrogenation of ethane on Pt-Sn impregnated monoliths

A monolithic FEM solver for an ALE formulation of fluid-structure interaction with configuration for numerical benchmarking

We investigate a monolithic algorithm to solve the problem of time dependent interaction between an incompressible viscous fluid and an elastic solid. The continuous formulation of the problem and its discretization is done in a monolithic way, treating the problem as one continuum. The Q2/P1 finite elements are used for the discretization and...

Interface-GMRES(R) Acceleration of Subiteration for Fluid-Structure-Interaction Problems

Subiteration forms the basic iterative method for solving the aggregated equations in fluid-structure-interaction problems, in which the fluid and structure equations are solved alternately subject to complementary partitions of the interface conditions. However, this subiteration process can be defective or inadequate, as it is endowed with...

Fischer-Tropsch synthesis revisited; efficiency and selectivity benefits from imposing temporal and/or spatial structure in the reactor

Catalysis engineering on three levels

The relevance of levels in space and time for chemical engineering are discussed. Catalysis Engineering is introduced as an emerging new discipline. In Catalysis Engineering three levels can be distinguished: the microlevel focusing on molecules and catalytic sites, the mesolevel focusing on the catalyst particle and the catalytic reactor, and...
