... (DMO) and much work has been carried out over the last few years to enhance this capability through process and catalyst modifications. Saudi Aramco's R&DC and JGC C&C, a leading catalyst developer and manufacturer in Japan, have also collaborated to develop a catalyst system to enable...

..., the selection process includes a survey on users to get their feedback on performance of the proposed catalyst systems. Finally, an economic evaluation on the technically acceptable catalyst systems, together with the performance guarantee and users' comments, will determine the winning catalyst system...

... and this unique shape can not only reduce the diffusion distance of the catalyst but also helps maintain a low pressure drop of catalyst bed. By optimizing the combined catalyst system and operating conditions, many sour residues with high contents of metals, sulfur, nitrogen and CCR can be hydrotreaded...

... Abstract. Alkylate represents the ideal blending component for low-emission gasolines such as the American reformulated gasolines. Conventional alkylation technologies still use the catalyst systems developed in the 1940s, i.e. H, SO, and HF, and suffer from a number of drawbacks. Attempts...

... a mixture of trans and Cis isomers. Second, the preferred mode of addition is that the ethylene becomes attached to the triphenylphosphine Catalyst System Ethylene Chexadiene reaction mMole hydride selectivity acetylacetonate diphosphine ethylene pressure butadiene cobalt polymerization...

... and with recycle of unconverted product to extinction. Recycle processing a cracked gas oil blend consisting mostly of coker gas oils and containing 750 ppm. nitrogen, resulted in an ultimate cs-400 o F. naphtha yield of 113 vol. % with a hydrogen consumption of 2400 SCF/B. For using the new catalyst system...
