【摘要】The technical achievement relating to the research on acetal hydrogenation catalyst for manufacturing high-purity 1,4-butanediol and its commercial scale-up technique developed by the SINOPEC Fushun Research Institute of Petroleum and Petrochemicals (FRIPP) has passed the technical appraisal organized by the Science and Technology Division of the Sinopec Corp. The experts attending the appraisal meeting, after having unanimously recognized that this hydrogenation catalyst has an appropriate pore structure and acidic property along with good low-temperature reducibility with all quality indicators reaching or exceeding the level of similar overseas catalysts, have recommended to conduct a commercial scale test as soon as possible.
