N2 - The optimization of the thermal treatment of cationic starch in the paper industry offers theopportunity to reduce the energy consumption of this process. Four different industrially relevantcationic starches, varying in source, cationization method and degree of substitution were treatedby a steam-jet cooking procedure, comparable to industrially employed starch cooking processes.The influence of the starch properties and cooking parameters on the adsorption behavior of thestarches on cellulosic pulp was investigated. The adsorbed amount was affected by the cookingtemperature and the type of starch. For some starch grades, a cooking temperature of 115 ◦C can beemployed to achieve sufficient starch retention on the pulp fibers. The energy consumption couldfurther be reduced by cooking at higher starch concentrations without loss of adsorption efficiency.
