Hydrodesulfurization and hydroconversion of heavy FCC gasoline on PtPd/H-USY zeolite

Imidazolium-based ionic liquids as novel organic SDA to synthesize high-silica Y zeolite

“…X-type zeolite with a SiO 2 /Al 2 O 3 ratio of 2.2-3 has been used as an important adsorbent for gas separation and cleaning [2,3]. Y-type zeolite with a SiO 2 /Al 2 O 3 ratio of 3-5 has been widely used as a catalyst for oil refining, particularly for fluid catalytic cracking (FCC) processes [4][5][6][7]. Zeolite Y is the active component of the catalytic cracking catalyst, and its catalytic performance is mainly dependent on its framework SiO 2 /Al 2 O 3 ratio [8][9][10].…”

HDS, HDN and HDO of FCC gasoline spiked with benzothiophene over PtPd/H-USY

“…In our previous R&D work we attempted to enlarge the applicability of supported noble metal catalysts. It has been reported that PtPd/USY is suitable to reduce the sulfur content of FCC gasoline fractions [27,28]. Moreover, PtPd/USY proved to be selective for HDS of full range FCC naphtha [27].…”

Metal–Organic Frameworks as a Potential Platform for Selective Treatment of Gaseous Sulfur Compounds

“…To date, source control efforts have reduced the emission of sulfurous compounds by 30–40%. Various techniques that have been used include liquid-phase chemical scrubbing, ,− hydrodesulfurization, ,− biological processes (e.g., biofilters, bioscrubbers, and biotrickling filters), − ,− catalytic oxidation, , and adsorption. ,,,− Nonetheless, it is still important to reduce their concentration to parts per billion (ppb) or parts per trillion levels (ppt) . In addition, most of the above technologies are based on chemical adsorption, which invariably requires higher energy and chemical processing penalties than physical adsorption. ,,,, Thus, it becomes important to develop new technologies that employ anticorrosive and moisture-stable materials in order to ensure improved energy efficiency, low-cost processing, and possible reusability.…”
