“…In this context, magnetite nanoparticles have been attracted much attention for various organic reactions. 12,13 Biomass is the only carbon containing renewable resource. More importantly, their unique paramagnetic properties and inherent insolubility allow them to be efficiently separated from the reaction mixtures by a magnet.…”

A nano-Fe 3 O 4 -CoO x catalyst was prepared via a simple wet impregnation method. The nano-Fe 3 O 4 -CoO x catalyst showed good catalytic performance for the conversion of 5-hydroxymethylfurfural into 2, 5-furandicarboxylic acid (FDCA) with t-BuOOH as the oxidant. Several important reaction parameters were explored, with the highest FDCA yield of 68.6% obtained from HMF after 15 h at a reaction temperature of 80 o C. One-pot conversion of fructose into FDCA was also successful via two steps. Catalytic conversion of fructose over Fe 3 O 4 @SiO 2 -SO 3 H yielded 93.1% HMF, which was oxidized in-situ into FDCA with a yield of 59.8%. Furthermore, recycling of nano-Fe 3 O 4 -CoO x was accomplished with the help of a magnetic field. Nano-Fe 3 O 4 -CoO x showed high stability in the reaction process. The use of non-precious metals and no requirement of a base additive made this method much more economical and environmental-friendly.

Original scientific paper Renewable sources should be preferred by a modern society and this should be done not only in the areas of material engineering. Jatropha curcas L. is a plant with a high potential with many technologically utilized parts among which seeds most of all. The seeds of the plant serve for the pressing of oil. During this technological process worse utilizable commodities such as pressed cakes, seed shells or pressed seed kernels are gained except for primary commodities (oil). A meaningful utilization of these secondary biocommodities is the key for optimization of the whole technological process. An experiment describes mechanical properties of an epoxy resin filled with commodities from the pressing of Jatropha curcas L. treated by the mechanical milling. The epoxy resin (Glue Epox Rapid) filled with microparticles of shells (67,8 µm), of seed cakes (108,1 µm) and of seed kernel cakes (82,7 µm) was used in the experiment. Keywords: epoxy resin; hardness; tensile strength; utilization of waste Iskorištenje otpada nastalog obradom biljke Jatropha curcas L. u biokompozitima -adhezivno-kohezivne karakteristike i trošenjeIzvorni znanstveni članak Suvremeno društvo bi trebalo preferirati obnovljive izvore i to bi se trebalo činiti ne samo u području obrade materijala. Jatropha curcas L. je biljka velikog potencijala s mnogo tehnološki iskoristivih dijelova. Među njima prvenstvo pripada sjemenkama. One služe za dobivanje ulja. Tijekom tog tehnološkog postupka, osim tog osnovnog proizvoda (ulje) dobivaju se i slabije iskoristivi materijali kao sprešani talog, ljuske sjemenki ili sprešane jezgre sjemenki. Korisna uporaba tih sekundarnih bioproizvoda predstavlja ključ za optimizaciju čitavog tehnološkog postupka. Eksperiment pokazuje mehanička svojstva epoksidne smole ispunjene proizvodima dobivenim prešanjem Jatropha curcas L. obrađene mehaničkim drobljenjem. U eksperimentu je upotrebljena epoksidna smola (Glue Epox Rapid) uz dodatak mikročestica ljuski (67,8 µm), sprešanih sjemenki (108,1 µm) i jezgri sjemenki (82,7 µm).

Gasification of biomass has great potential for satisfying the ever-growing demand for a clean and renewable energy source. In this study, sunflower seed pulp, a waste product of sunflower oil factories, was gasified using K 2 CO 3 as a catalyst and dry air as a gasifying agent. Effects of reaction temperature, dry air flow rate and catalyst ratio on the gas product composition were investigated. The highest hydrogen yield (5.45 mol/kg biomass) was achieved at 750 °C, with the addition of 20 wt.% K 2 CO 3 and with a dry air flow rate of 3 L/h.
