This work presents an experimental holistic approach for the design of a continuous catalytic conversion process of carbohydrates derived from waste biomass to 5-hydroxymethylfurfural (5-HMF) using a tin-doped active carbon catalyst. In this report, apple biomass waste is used as a model component as …

Pyrolysis liquids from lignocellulosic biomass have the potential to be used as a feed for aromatics such as benzene, toluene, and xylenes (BTX) using catalytic upgrading with zeolites. We here report an experimental study on the conversion of various pyrolysis oil fractions to determine the most suitable …

This paper evaluates the potential impacts of introducing low-carbon intensity hydrogen technologies in two oil refineries with different complexity levels, emphasizing the role of hydrogen production in reducing CO2 emissions. The novelty of this work lies in three key aspects: Comprehensive system …

This thesis examines how oil palm plantation characteristics affect the presence and biomass of earthworms in Malaysia. The research was carried out across 228 plots in Selangor and Negeri Sembilan. Results show that industrial plantations host more earthworms, while smallholder plantations support heavier …

Lectorinstallatie en Lectorale rede van dr. ir. Joàn Teerling. Gedurende de middag werden er presentaties gegeven in het kader van duurzame gassen en brandstoffen.

Climate change calls for an energy transition utilizing all available renewable energy resources, such as bioenergy from biomass. However, the use of biomass is debated in society, and public acceptance is low or lacking. This survey-based research demonstrates for the first time that public acceptance …

Restoration engineering measures, such as managed realignments or building groins, modify the environmental characteristics of coastal intertidal ecosystems. Creating physical modifications that are beneficial to an intertidal system's ecology necessitates an in-depth understanding of the relationships …

The Netherlands is dependent on artificial structures for water safety. In addition to water safety the artificial structures also provide habitat for different aquatic species. When designing artificial structures like dikes and breakwaters adjustments can be taken to increase species richness or stimulate …

Lignocellulose biorefining is a promising technologyfor the sustainable production of chemicals and biopolymers.Usually, when one component is focused on, the chemical natureand yield of the others are compromised. Thus, one of thebottlenecks in biomass biorefining is harnessing the maximumvalue from …

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative …
