Utilization of Sugar Beet Pulp by Getting Activated Carbon

The formation and properties of sugar beet pulp have been analysed in the article. It has been proposed to use it as raw material to produce activated carbon. A better hydrophilicity of the obtained carbon in comparison with the samples of industrial production has been shown. Structural features and a porous structure of carbon made of sugar beet pulp have been analysed by X-ray diffraction and small angle scattering methods. It has been found that pores with average radii of inertia of 3.5 nm make the main contribution to the pore structure.

Development of Ammophos Production Technology from Algerian Phosphorites

Technological aspects of ammophos production using Algerian phosphorites as a raw material have been investigated. The necessity of increased consumption of sulphuric acid during the Algerian phosporites processing compared with apatite processing has been grounded. The dependence of pH solution on NH3:H3PO4 molar ratio has been determined during neutralization of extraction phosphoric acid prepared from Algerian phosphorites. The necessity of acid solution deeper neutralization in the technology of extraction phosphoric acid production has been proved.

Pulp Obtaining from Corn Stalks

The influence of basic technological parameters of the organosolvent delignification of corn stalks process on the pulps quality has been investigated. The adequate regression equations of the process of obtaining pulps using the method of full factorial experiment have been obtained. The optimal values of technological parameters of organosolvent delignification of corn stalks have been calculated.
