AB  - Many industrial scale trickle bed reactors (TBR) operate at lower liquid superficial velocities ( lt 0.5 cm/s) at which the catalyst particle are not completely wetted. This phenomenon of incomplete wetting has therefore received significant attention and numerous studies have addressed the influence of wetting on the overall rate, conversion/selectivity behavior, and heat effects in TBR. The incomplete wetting conditions correspond to stagnant liquid pockets due to lower liquid superficial velocity which could cause significant influence on reactor performances. In this paper, several models for wetting efficiency in TBR on industrial level are examined and influence on reaction rate and reactor performance is discussed.
AB  - Mnogi reaktori sa pakovanim slojem katalizatora (TBR) u industrijskim procesima za hidroobradu rade pri malim površinskim brzinama tečne faze ( lt 0,5 cm/s) pri čemu su čestice katalizatora samo delimično ovlažene. Ovaj fenomen delimične ovlaženosti katalizatora detaljno je ispitivan, kao i uticaj stepena ovlaženosti na brzine reakcija koje se odvijaju u procesu, na konverzije, selektivnost, i na porast temperature u reaktoru. U ovom radu upoređeni su rezultati nekoliko različitih modela za izračunavanje ovlaženosti u industrijskom reaktoru sa pakovanim slojem katalizatora, kao i uticaj ovlaženosti na brzine hemijskih reakcija i na rad industrijskog rektora.

AB  - Reducing the sulfur content of diesel fuels may require adjusted operation of low-pressure hydrotreater units. A mathematical model for co-hydrotreating of straight run gas oil blended with fluid catalytic cracking naphtha and light cycle oil was developed using an axial distribution of phase equilibrium and effective wetting in the catalytic reactor. The model assumes that hydrodesulfurization (HDS) and hydrodearomatization reactions occur on the catalyst surface which is in contact with the vapor or liquid phase. Kinetic equations of HougenWatson type were used to describe HDS reactions for different classes of sulfur compounds. Model results were validated using the industrial test run data, and very good predictions of overall sulfur conversion and reactor temperature were obtained. Simulations of reactor operation at different pressures, temperatures, and H-2 purities confirm that reaction pressures of around 100 bar and high-purity hydrogen streams are required for almost complete removal of sulfur compounds.
