Enhanced Bio-BTX Formation by Catalytic Pyrolysis of Glycerol with In Situ Produced Toluene as the Cofeed

Wang, Fukang; Kramer, Thomas Sjouke; Yan, Bin; Zhu, Lin; Zhu, Yuezhao; Heeres, Andre (Biobased Chemistry & Refinery); Ciolca, Diana; Jan Heeres, Hero; He, Songbo

The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at …

Geogrid Stabilisation in asphalt paved roads

Siebe Theodoor van der Zee (Student); Piet Dekker (Begeleider); Leo Kuljanski (Begeleider)

The use of TriAx geogrids to stabilise the granular base layer of asphalt paved roads, is ever increasing. However, the effect a stabilising geogrid has on the entire pavement structure is still derived from a foundation reduction factor, instead of being calculated directly. Practical experience showed …

Enzymatic degradation of granular potato starch by Microbacterium aurum strain B8.A

Sarian, Fean D; van der Kaaij, Rachel M; Kralj, Slavko; Wijbenga, Dirk-Jan; Binnema, Doede J.; van der Maarel, Marc J E C; Dijkhuizen, Lubbert

Microbacterium aurum strain B8.A was isolated from the sludge of a potato starch-processing factory on the basis of its ability to use granular starch as carbon- and energy source. Extracellular enzymes hydrolyzing granular starch were detected in the growth medium of M. aurum B8.A, while the type strain …

Synthesis, analysis and reduction of 2-nitropropyl starch

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Bergsma, Jack; Kellogg, Richard M.; Bleeker, Ido Pieter

Granular 2-nitropropyl potato starch was synthesized by reaction with 2-nitropropyl acetate in an aqueous suspension. Nitroalkylation occurs preferentially with the amylose fraction of potato starch, as was confirmed by leaching experiments and digestion of the modified starch with α-amylase. The 2-nitropropyl …

Cross-linking of starch with bifunctional precursors of nitroalkenes

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Kellogg, R. M.; Bleeker, Ido Pieter

Granular starch was cross-linked with 1,3-di-O-acetyl-2-nitro-1,3-propanediol (1), 1,3-di-O-pivaloyl-2-nitro-1,3-propanediol (2), 2-nitro-3-O-pivaloyl-1-propene-3-ol (3), 1,3-di-O-acetyl-aci-2-nitro-1,3-propanediol (4), 1,3-di-O-pivaloyl-aci-2-nitro-1,3-propanediol (5) and 1,6-di-O-acetyl-2,5-dinitro-1,6-hexanediol …
