Реферат: An alternative method of joint disposal of acid tars (high-sulphur petrochemical waste) with wood-chemical industry and agriculture wastes, at which additional neutralization or trapping of sulphur acid decomposition products is not required, was investigated. At thermal treatment of a mixture of acid tar (a mixture of sulphuric acid and heavy oil fractions), template (high-ash biomass) and binder (furfurol, formaldehyde or resorcinol), sulphated carbon materials applicable as catalysts for a broad range of acid-catalyzed processes were obtained. The impact of synthetic methods for materials on acid and textural characteristics of materials was explored using BET, TGA, XPA, XPS methods and IR spectroscopy. Optimal conditions for the preparation of carbon materials with developed specific surface (up to 168 m2/g) and a high concentration of sulpho groups (up to 4.55 mass % SO3H) were found. The addition of a template allows increasing calcination temperature (from 225 to 275 oC) that is required to achieve high specific surfaces, without a decrease in acidities (sulpho groups concentration) final samples. Testing of catalytic properties of the carbon materials obtained in modelling of a catalytic process for esterification of enanthic acid with methanol was performed.
