Autor: Goond Hongmanee, Patchanee Chammingkwan, Toshiaki Taniike, Minoru Terano

Publikováno v: Polyolefins Journal, Vol 3, Iss 1, Pp 47-57 (2016)

Mg(OEt)2 with spherical morphology is one of the most important precursors for the preparation of industrial Ziegler-Natta catalysts. In the present article, morphology evolution of Mg(OEt)2 particles is studied in the course of the synthesis. The mo

Numerical simulation of gasification with a one-dimensional particle submodel for char structure evolution

Autor: Hartmut Spliethoff, Robert Schwarz, S. DeYoung

Publikováno v: Fuel. 293:120492

The exact knowledge of reaction rate, diameter, and density of a char particle is important for precise computational fluid dynamics (CFD) simulations of gasifiers. Most of the present research treats char particles as homogeneous with respect to den
