Title:
コバルト含有炭化水素合成触媒前駆体を調製する方法
Document Type and Number:
Japanese Patent JP2014518757
Kind Code:
A
Abstract:
A process for preparing a cobalt-containing hydrocarbon synthesis catalyst precursor includes calcining a loaded catalyst support comprising a catalyst support supporting a cobalt compound. The calcination includes heating the loaded catalyst support over a heating temperature range of 90° C. to 220° C. using (i) one or more high heating rate periods during the heating over the heating temperature range wherein heating of the loaded catalyst support takes place at a heating rate of at least 10° C./minute, and wherein a gas velocity of at least 5 m3n/kg cobalt compound/hour is effected over the loaded catalyst support, and (ii) one or more low heating rate periods during the heating over the heating temperature range wherein heating of the loaded catalyst support takes place at a heating rate of less than 6° C./minute. The cobalt compound is thereby calcined, with a cobalt-containing hydrocarbon synthesis catalyst precursor being produced.
