PAGE 4 - FPHENOLIC MONOMERS IN AROMATIC SYNTANS AND THEIR INFLUENCE ON LEATHER: (PENDING) RESTRICTED COMPOUNDS 1. Introduction Aromatic syntans play an important role in the retanning step or wet end process of leather making. Although considerable progress has been made in FCC gasoline hydrorefining, it is still a great challenge to develop new catalysts and single-stage reactors to realize deep refining whilst retaining octane number. The core of one-pot hydrogenation is to develop a deep desulfurization catalyst and maintain th Formally, Advanced Refining Technologies LLC (ART) is the 50/50 joint venture between affiliate companies of Chevron and W. R. Grace & Co. for the development, manufacture, sale, and service of a full portfolio of state-of-the-art hydroprocessing catalysts and lubes. In addition to the hundreds of employees fully dedicated to ART and its 田中貴金属の「PROX触媒」. PROX触媒は改質ガス中に含まれる一酸化炭素を酸素によって選択的に酸化除去するための触媒です。. 一酸化炭素は固体高分子型燃料電池の電極を被毒させ電池性能を劣化させるため、改質ガス中の一酸化炭素濃度を10ppm以下にする Hydroprocessing is broadly classified as a catalytic refining process carried out in the presence of hydrogen at higher temperatures and hydrogen partial pressures either to improve the quality of fuels/lubricating oils (hydrotreating) or convert the low-value vacuum gas oil (VGO) and residue into high-value fuels/lubricating oils (hydrocracking).
