HYDROCARBON CONVERSION CATALYSTS AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2006 - IPC B01J21/06 B01J23/40 B01J21/04 B01J27/53 B01J37/03 C07B35/08 

FIELD: catalyst preparation methods.

SUBSTANCE: invention, in particular, relates to catalyst based on synthetic mesoporous crystalline materials and provides hydrocarbon conversion catalyst composed of: group VIII metal/SO₄ ²-/ZrO₂-EOx, where E represents element of the group III or IV of Mendeleev's periodic table, x = 1.5 or 2, content of SO₄ ²- is 0.1 to 10% by weight, ZrO₂/EOx molar ratio is 1:(0.1-1.0), which has porous crystalline structure with specific surface 300-800 m²/g and summary pore volume 0.3-0.8 cm³/g. Preparation method comprises precipitation of zirconium compounds, in particular zirconium hydroxide or zirconyl, under hydrothermal conditions in presence of surfactant to form mesoporous phase, which is stabilized with stabilizing agents: group III and IV elements. When stabilization is achieved, if necessary, acidity is adjusted and group VIII metal is added.

EFFECT: increased specific surface area and heat resistance at simplified technology.
