reg no: ETF5359
project type: Estonian Science Foundation research grant

duration: 01.01.2003 - 31.12.2006
description: Industrial retorting of Estonian local kukersite oil shale results in abundance of various individual and homologous series of phenolic compounds. Only few of them can be sold at a high price as pure compounds meeting requirements and demand in western markets. One of the most effective opportunities to upgrade the water- and oil soluble phenols present in shale oil and in phenolic waters is those selective dealkylation. For that purpose novel processes occurring in fluid phase are carried out. The main purpose is to work out the methods for maximum converting of oil shale originated phenols to phenol, resorcinol, 5-methylresorcinol, naphthols and cresols. Residual nonpolar hydrocarbonaceous part as by-product can be added to the neutral oil to elevate its qualities as feedstock for diesel oil production. The results contribute furter modification rearrangement of the pre-existent industrial practice.
