Catalytic Hydrotreating of Triglycerides for the Production of Bioparaffin Mixture
TL;DR: In this paper, the applicability of an expediently modified NiMoW/Al2O3 catalyst for the conversion of specially pretreated Hungarian sunflower oil with high oleic acid (>90%) content was ennobled for their experiments to produce motor fuels.
Journal ArticleDOI
Fuel Purpose Hydrotreating of Vegetable Oil on NiMo/γ-Al2O3 Catalyst
TL;DR: In this article, the applicability of commercial NiMo/γ-Al2O3 catalyst for conversion of specially pretreated Hungarian sunflower oil to produce motor fuel components was investigated.
Journal ArticleDOI
Propylene synthesis via isomerization–metathesis of 1-hexene and FCC olefins
Gyula Novodárszki,Blanka Szabó,Róbert Auer,Katalin Tóth,László Leveles,Róbert Barthos,Gábor Turczel,Zoltán Pászti,József Valyon,Magdolna R. Mihályi,Robert Tuba +10 more
TL;DR: In this paper, Zeolite H-beta (HBEA) was applied as an isomerization catalyst for the conversion of 1-hexene or olefins obtained by fluid catalytic cracking (FCC) to propylene via ISOMET using ethylene as a cross-coupling agent.
Journal ArticleDOI
Alternative diesel fuels with high hydrogen content in their molecular structures
Jenő Hancsók,Oliver Visnyei,András Holló,László Leveles,Artur Thernesz,Géza Varga,József Valyon +6 more
TL;DR: In this paper, the effect of feedstock additives was investigated on the catalyst performance, such as activity, selectivity, product yield and catalyst lifetime, and it was concluded that coke precursors, which were formed from olefinic components reduced the catalytic performance.

TL;DR: In this article, a process for the production of paraffin fractions by a special hydrocracking, wherein the feedstock is treated with hydrogen in the presence of heterogeneous catalyst applied on a carrier at 160-420°C temperature and 5-100 bars pressure, where the volumetric hydrogen to feedstock ratio is 200-2000 Nm 3 /m 3 and the hourly feedstock load is up to 10 m 3 feedstock/m 3 catalyst.
