    • Monomodal or polymodal catalyst supports or catalysts having a BET specific surface area of from 0.01 to 250 m.sup.2 /g and a monomodal or polymodal pore size distribution having a mean pore diameter of from 50 to 300,000 nm measured by the mercury pressure porosimetry method, whereina) from 10 to 95% of the pore volume is at from 0.1 to 3 times the mean pore diameter and/orb) from 10 to 80% of the pore volume is at from 0.4 to 3 times the mean pore diameter and/orc) from 50 to 95% of the pore volume is at from 0.1 to 1 times the mean pore diameter and/ord) from 50 to 80% of the pore volume is at from 0.4 to 1 times the mean pore diameter ande) the width at half height of the pore size distribution is less than 0.5 times the mean pore diameter,which are useful for preparing chlorine from hydrogen chloride in a non-steady-state Deacon process, for the reaction of ethylbenzene to give styrene in a non-steady-state oxydehydrogenation, for preparing aziridine from ethanolamine, in reductions, hydrogenations, oxidations, dehydrogenations, acid- or base-catalyzed reactions or reactions in a fluidized bed, for removing combustion residues from diesel exhaust gases and for removing NO.sub.x from waste gases, in bioreactors together with bacteria and as biocatalyst supports with immobilized enzymes or microbes, and a process for producing said monomodal or polymodal catalyst supports or catalysts.
    • 单峰或多模式催化剂载体或BET比表面积为0.01至250m 2 / g的催化剂载体和通过汞压孔隙度法测量的平均孔径为50至300,000nm的单峰或多模孔径分布,其中a )孔体积的10至95%为平均孔径的0.1至3倍和/或b)孔体积的10至80%为平均孔径的0.4至3倍和/或c )孔体积的50至95%为平均孔径的0.1至1倍,和/或d)孔体积的50至80%为平均孔径的0.4至1倍,e) 孔尺寸分布的半高宽度小于平均孔径的0.5倍,这可用于在非稳态Deacon方法中从氯化氢制备氯,用于乙苯的反应, 稳态氧化脱氢,用于从乙醇胺制备氮丙啶,还原 ns,氢化,氧化,脱氢,酸或碱催化的反应或在流化床中的反应,用于从生物反应器中连同细菌和作为生物催化剂载体与固定化酶一起从柴油机排气中除去燃烧残余物并从废气中除去NOx 或微生物,以及用于生产所述单峰或多模式催化剂载体或催化剂的方法。
