Properties of adsorbents used for bleaching of vegetable oils and animal fats

Vilppu Kuuluvainen, Päivi Mäki‐Arvela, Anne‐Riikka Rautio, Krisztian Kordas, więcej

Journal of Chemical Technology & Biotechnology > 90 > 9 > 1579 - 1591

BACKGROUNDTwo types of bleaching earths used in the production of green diesel, namely, sepiolite and palygorskite, were characterized by various physico‐chemical methods, such as nitrogen adsorption, Hg porosimetry, scanning electron microscopy, transmission electron microscopy, energy dispersive X‐ray analysis, Fourier transfom infrared spectroscopy, pH of the clay slurry, thermogravimetrical analysis...

Extraction of Spent Bleaching Earth in the Production of Renewable Diesel

Vilppu Kuuluvainen, Päivi Mäki‐Arvela, Kari Eränen, Anton Holappa, więcej

Chemical Engineering & Technology > 38 > 5 > 769 - 776

The extraction of oils based on animal fat and vegetable oil from two types of spent bleaching earths, namely from the acidic sepiolite and the nonacidic palygorskite, was investigated by the Soxhlet method with hexane as a solvent. The yields of oil were independent of the feedstock, whereas a much lower oil yield was obtained with palygorskite exhibiting also a smaller surface area as compared to...

Phospholipid adsorption from vegetable oils on acid-activated sepiolite

Markku Laatikainen, Waroonkarn Srithammavut, Blanka Toukoniitty, Ilkka Turunen, więcej

Adsorption > 2015 > 21 > 5 > 409-417

In this study, adsorption of natural and model phospholipids (PL) from camelina and rapeseed oils on acid-activated sepiolite has been studied. Adsorption isotherms were determined for total phosphorus and for individual PL at different conditions. Influence of acid-degumming with citric acid as well as of type and ionic form of the phospholipid was investigated. The experimental data were correlated...

Ethyl pyruvate hydrogenation under microwave irradiation

Blanka Toukoniitty, Oriane Roche, Jyri-Pekka Mikkola, Esa Toukoniitty, więcej

Chemical Engineering Journal > 2007 > 126 > 2-3 > 103-109

Enantioselective and racemic hydrogenation of ethyl pyruvate over Pt/Al ₂ O ₃ catalyst was investigated under conventional and microwave dielectric heating. Experiments were carried out in a single-mode microwave loop reactor, equipped with a heating band, to directly compare the efficiency of the conventional convective/conductive heating and microwave dielectric heating. A sequence...
