LS系列硫磺回收催化剂工业装置使用总结

对比总结了 L S系列催化剂的使用情况。结果表明 ,在一级转化器均装填使用 L S- 931Al2 O3 基催化剂的前提下 ,二级转化器上部装填 L S- 971脱氧保护型催化剂 ,下部装填 L S- 811Al2 O3 催化剂后 ,与单纯使用 L S- 931催化剂相比 ,单器转化率由 6 4.1%提高到 70 .1% ,有机硫水解率由 96 %提高到接近 10 0 % ,两项合计使装置总硫转化率由 95 .1%提高到 96 .2 % ;若与两个转化器全部使用 L S- 811催化剂相比 ,则装置总硫转化率可由 94.49%提高到 96 .2 %使用效果更加显著。

MMC——High Propylene Selectivity DCC Catalyst

RIPP has developed the third generation novel DCC catalysts aimed at increasing the propylene yield, named as the MMC series catalysts. This catalyst is of the MFI structure composed of the ZSP zeolite as the main active component, which has higher capability for producing low-carbon olefins, in particular the propylene. The commercial application of this catalyst at SINOPEC Anqing Petrochemical Company has revealed that the adoption of the MMC-2 catalyst has resulted in a 1.6-4.0 percentages increase in propylene yield under basically similar conditions in terms of the feedstock property and process operating regime coupled with reduction in gasoline olefin COntent and increase in aromatic content to improve the gasoline quality.
