Pt-loaded β-type zeolite catalysts with constant Pt content (0.11 wt.%) and similar pore structure were prepared using a water-in-oil (w/o) microemulsion. The effect of Pt particle synthesis conditions using microemulsion (a type of Pt complex-forming agents and the molar ratio of complex-forming agent to Pt4+) on loaded Pt particle size was investigated. The Pt particle size of the Pt catalyst...

In order to produce petroleum alternatives from biomass, a significant amount of research has been focused on oils from microalgae due to their origin, which would not affect food availability. Nanoporous hybrid catalysts composed of ns Al₂O₃ and zeolites have been proven to be very useful compared to traditional catalysts in hydrotreating (HT), hydrocracking (HC), and catalytic cracking (CC) o...

Article history: Received 25 July 2007 Received in revised form 21 February 2008 Accepted 1 April 2008 The hydroprocessing technologies such as hydrocracking, hydrofinishing provide an opportunity to modify the chemistry of hydrocarbons to improve the properties of petroleum base oils. Quantitative H and C NMR data has been used to generate average structural profile for a variety of base oil s...

Hydrogenation reactions have a variety of applications in the chemical industry which is shown by the corresponding products, such as ammonia, methanol, and polyamides. In petrochemistry, the addition of hydrogen is used to adjust properties of product mixtures, e.g. in the hydrocracking or hydrotreating. For renewables the same is already feasible or first proofs of concept were already shown....
