摘要: A new knitted silica fibre catalyst was introduced into liquid-phase hydrogenation of organic compounds. The combines the advantages slurries and large particles: diffusional limitations are suppressed is immobile. Nickel-impregnated fibres were used in citral to citronellal citronellol a tubular glass reactor where packed two layers. liquid phase recirculated while gas flowing concurrently through vent. highest selectivities desired product, citronellol, exceeded 90%. performance competitive with conventional crushed nickel catalyst.
