The aim of the work was to study the isomerization of limonene on zeolite-containing biporous acid catalysts based on kaolin. Zeolite catalysts were synthesized from Ukrainian kaolin and characterized by using XRD, XRF, DTA/TG, IR-spectroscopy, low-temperature nitrogen adsorption, and pyridine sorption. Micro-mesoporous materials isomerize limonene at 160°C. The main reaction product on acid catalysts was terpinolene, while the original metakaolin microsphere catalyzes mainly the limonene condensation. The maximum yield of isomers is of 60–65% at 80–90% conversion. The obtained results show that the studied samples do not have a significant accumulation of carbonaceous deposits because limonene has high solubil |
