Nowadays, lignocellulosic agro-wastes, as rice husks, walnut shells, almond shells, woody wastes, etc., are considered on the one hand as a serious environmental concern and on the other hand as a source of highly concentrated carbon, which can be tr

The changes of phase content of the support in the interval 850–1150°C were studied after modification of Pt/Al2O3 catalyst with vapors of CrO2Cl2 or SnCl4. It is shown that, upon introducing a second transition element, the temperature of phase t
