This report discusses the easy and cheap preparation of SnCl2 exchanged Brønsted acidic Amberlyst-15 ion exchange resin prepared by ion exchange of an aqueous SnCl2 solution at room temperature. The prepared materials were tested in the conversion of sugars, being glucose, fructose and saccharose to …

Catalytic pyrolysis of crude glycerol over a shaped H-ZSM-5 zeolite catalyst with (partial) recycling of the product oil was studied with the incentive to improve benzene, toluene, and xylene (BTX) yields. Recycling of the polycyclic aromatic hydrocarbon (PAH) fraction, after separation from BTX by distillation …

Presentatie verzorgd voor het NVDO over duurzame productie van plastic (BioBTX). Het bevatte informatie over de populatiegroei en de groei in materiaalwinning. Verder gaf het antwoord op de volgende vraag: duurzame consumptie en productie, benutting van natuurlijke grondstoffen; een aantrekkelijk alternatief …

Tijdens deze presentatie vertelde André over hoe duurzame materialen een aantrekkelijk alternatief zijn voor de synthese van “high volume” chemicaliën, inclusief aromaten. Hiernaast ging hij in op hoe BioBTX en de RUG vernieuwende en meer rendabele werkwijzen hebben bedacht om aromaten uit biomassa te …

Bio-aromatics (benzene, toluene, xylenes, BTX) were prepared by the catalytic pyrolysis of six different black liquors using both in situ and ex situ approaches. A wide range of catalysts was screened and conditions were optimized in microscale reactors. Up to 7 wt % of BTX, based on the organic fraction …

As anyone who has travelled the dissertation road knows the process dominates until the end of that road is reached. After the fireworks, it is time, high time, to share the outcomes outside of a small circle of experts. This monograph is part of the catalytic goals of a study undertaken between 2006 …

Background: Glucocorticoids are potent anti-inflammatory agents used for the treatment of diseases such as rheumatoid arthritis, asthma, inflammatory bowel disease and psoriasis. Unfortunately, usage is limited because of metabolic side-effects, e.g. insulin resistance, glucose intolerance and diabetes. …

The scope of this thesis of Gerrit Bouwhuis, lecturer at Saxion Research Centre for Design and Technology in Enschede is the development of a new industrial applicable pre-treatment process for cotton based on catalysis. The pre-treatment generally consists of desizing, scouring and bleaching. These …
