Diffusion Equation - Finite Cylindrical Reactor

This finite cylindrical reactor is situated in cylindrical geometry at the origin of coordinates. In order to solve the diffusion equation, we have to replace the Laplacian by its cylindrical form: Since there is no dependence on angle Θ, we can replace the 3D Laplacian by its two-dimensional form, and we can solve the problem in radial and .

composition of wood by thermal hydrolysis to improve the physico-mechanical properties and decay resistance of wood [1]. The heat-treated wood has some advantages, such as the improvement of dimensional stability with an increase of hydrophobicity, equalization of surface color, and increase of decay resistance. Because of these advan-

Modelling of homogeneously catalyzed hemicelluloses .

A tubular reactor system for continuous and catalyzed hydrolysis of hemicelluloses was tailor constructed. The reactor system consisted of two cylindrical preheating coils for the aqueous solution of hemicelluloses and the acid catalyst. The two streams (hemicelluloses and catalyst solution) were joint in a T-mixer and entered the reactor coil.

Hydrogen generation by means of catalyzed Mg-Al hydrolysis .

Based on considerations of reactivity, costs, and the volume of hydrogen which can be expected per mass fraction of metal, Al and Mg offer good possibilities in metal hydrolysis. Since these metals hardly react with water, however, a catalyst is used to accelerate the Mg-Al hydrolysis process. Experiments show that a mixture of Mg and Al reacts strongly with water in the presence of CO3O4 .
