Catalytic Hydrocracking of Thiophene with Nickel-Solid Acidic Catalyst

Acidic Mesoporous Zeolite ZSM-5 Supported Cu Catalyst with Good Catalytic Performance in the Hydroxysulfurization of Styrenes with Disulfides

Development of highly active heterogeneous catalysts is an effective strategy for modern organic synthesis chemistry. In this work, acidic mesoporous zeolite ZSM-5 (HZSM-5-M), acidic-free mesoporous zeolite TS-1 (TS-1-M), and basic ETS-10 zeolite supported metal Cu catalysts were prepared to investigate their catalytic performances in the hydroxysulfurization of styrenes with diaryl disulfides....

On Catalytic P Systems with One Catalyst

P systems are a computational model introduced by G. Păun in [4]. One of the basic variant considered there was P systems with catalysts and priorities; these systems where shown to be computationally universal. In [2], Sośık and Freund proved that priorities among the rules can be discarded from the model without any loss of computational power. Moreover, it was shown that for extended P syste...

Studying of Catalyst Deactivation in a Commercial Hydrocracking Process (ISOMAX)

Catalyst deactivation is usually indispensable, although the rate at which it occurs varies greatly. At first, this article discusses the causes of deactivation in a commercial hydrocracking unit called Isomax. Then, a 5-lump kinetic model including catalyst decay function for hydrocracking of vacuum gas oil in a commercial plant is proposed. The model considers vacuum gas oil (VGO) having boil...
