Optimization
of Acidic Treatment of Bentonitic Clays from the National Layers
Abstract
The investigations in
the field of the development of not expensive catalysts for the production of
environmentally safe fuels basing on synthesis-gas from biomass have been
performed. It was investigated the influence of acidic (sulphuric and
phosphorus acids) treatment on the specific surface Russian (Voronesch and
Khrasnodar bearthplaces) bentonitic clays. For determination of the optimal
conditions of acidic treatment the method of extremal experiment planning has
been applied. The full factor experiment was chosen as the plan; in such
experiment all factors combination are realized on all levels used for
investigations. The variable parameters were: concentration of acid,
temperature and time of acid treatment. The average pores diameter and specific
surface of clays were chosen as the response functions. The response surface
appearance is very complex.
