摘要：Tratarea .n prealabil a bentonitului L.rgu.a cu solu.ie diluat. de acid (pH 2), .n continuare fiind intercalat cu specii oligomerice de aluminiu, duce la modificarea propriet..ilor de suprafa.. ale adsorban.ilor intercala.i – a acidit..ii lor, a caracteristicilor sorb. ional-structurale .i a stabilit..ii termice. Cinetica conversiei acidului oleic la esterificarea cu alcool etilic este influen. at. de caracterul acid al catalizatorilor utiliza. i. Model.rile efectuate relev. c. adsorban.ii intercala. i, ob. inu.i pe baza bentonitului L.rgu.a, au perspective reale de a fi utiliza. i pentru ob.inerea biocombustibilului din uleiuri vegetale
其他摘要：Larguta bentonite prior treatment with dilute acid (pH 2) further being pillared with aluminum oligomeric species, result in modification of the surface properties of the adsorbents - acidity, sorption-structural characteristics and thermal stability. The kinetics of the conversion of oleic acid to esterification with ethylic alcohol is influenced by the nature of the acid catalysts used. Pillared adsorbents obtained on the basis of bentonite Larguta (RM) possess real prospects for obtaining bio-fuel from vegetable oils
