Over the past decades, the field of chemical engineering has witnessed an increased interest in unsteady-state processes. Multifunctional, as well as intensified chemical processes, may exhibit instationary behaviour especially when based on periodical operating conditions. Ideally, instationary processes lead to a higher yield and increased selectivities compared to conventional steady-state f...

Production of bio-based materials in biorefineries is coupled with the generation organic-rich process-wastewater that requires further management. Anaerobic technologies can be employed as a tool for rectification such hazardous by-products. Therefore, 5-hydroxymethylfurfural and its components were investigated their biodegradability continuous anaerobic process. The test included 5-hydroxyme...

In response to the growing trend of greenhouse gas emissions from production and use conventional fuels, COx free hydrogen generation is introduced as an alternative efficient energy carrier. Due hydrogen’s storage challenges, more be produced on-site by other chemical compounds for fuel cell applications. This work outlines (H2) ammonia (NH3) hydrous hydrazine (N2H4·H2O) catalytic decompositio...

Production of optically pure products can be based on simple unselective synthesis of racemic mixtures combined with a subsequent separation of the enantiomers. However, this approach suffers from a 50% yield limitation which can be overcome by racemization of the undesired enantiomer and recycling. Application of biocatalyst for the racemization steps offers an attractive option for high-yield...
