Effect of the Termal Treatment Temperature on the Durability and the Cracking Activity of the Catalysts on the Base of Modified Montmorillonite

Development of Heat Storage Materials Based on Commodity Paraffins

“…When using solid paraffin as a heat-storage material, the heat of crystallization and phase transition in the crystal state is usually used. In work [15][16][17][18][19][20] it is shown that solid paraffin has two phase transitions: in the crystalline state with the release and absorption of heat, as well as the release and absorption of heat during melting and evaporation. When a solid paraffin is heated, it undergoes phase transformations in the crystalline state, resulting in an increase in heat capacity, and when a higher temperature is reached, the paraffin melts, and its heat capacity again sharply increases.…”
