Objective

  • Improve yield & quality of CNF/CNT produced

    • Better dispersion of CNF/CNT

    • High CNF/CNT yield

    • CNF CNT

  • To improve yield & quality of CNF/CNT

  • To Improve drying process

  • for better catalyst dispersion

  • onto substrate

  • To optimize the optimum temp

  • for Fe reduction

  • To reduce drying time

  • To improve yield & quality

  • of CNF/CNT

Problem

Bad catalyst dispersion

Objective

To Improve drying process for better catalyst dispersion onto substrate


Previous Tech

Oven

45oC, Horizontal ventilation

New Tech

Drynoza

RT, vertical ventilation


Result

  • Catalyst Dispersion Improved

No sign of track of dried Fe salt

deposited on the bottles.
