ABSTRAK
Carbon loss dengan besar lebih dari 65% menjadi kendala utama dalam produksi
CNT skala pilot menggunakan reaktor gauze. Identifikasi carbon loss dilakukan dengan
menganalisis kemungkinan penyebab carbon loss seperti error pada pengukuran laju
alir produk, evaluasi perubahan laju alir umpan karena adanya katalis dan penumbuhan
CNT dalam reaktor, analisis komposisi gas produk dengan GC FID dan kemungkinan
terbawanya karbon sebagai partikulat dalam aliran produk. Hasil penelitian menunjukkan
bahwa carbon loss awal sebelum dianalisis dengan metoda diatas jauh lebih kecil dari
penelitian sebelumnya yaitu 27,64%. Hal ini dikarenakan laju alir umpan telah
dikalibrasi dengan kondisi reaktor berisi katalis bukan reaktor kosong. Carbon loss
mencapai 69,14% jika laju umpan yang digunakan pada perhitungan adalah hasil
kalibrasi saat reaktor kosong. Adanya katalis menyebabkan laju alir umpan yang masuk
lebih kecil 28% dari saat kondisi kosong. Error laju alir produk karena pengukuran
dengan bubble soap memberikan error perhitungan carbon loss ± 4,14%. Perubahan laju
alir umpan karena penumbuhan CNT dalam reaktor mengurangi besarnya carbon loss
sebanyak 4,97%. Sedangkan terdeteksinya hidrokarbon skunder dengan GC FID selama
produksi CNT berlangsung mengurangi carbon loss sebesar 5,41%. Selain itu, partikulat
yang terbawa oleh aliran produk sangat sedikit dan hanya mengoreksi carbon loss sebesar
0.05%.Dengan memperhitungkan semua faktor diatas, besarnya carbon loss pada
penelitian ini adalah (16,23 ± 4,14)%. Jika diasumsikan 4,14% carbon loss disebabkan
oleh error selama pengukuran laju produk maka besarnya carbon loss adalah 12,09% .
Artinya lebih dari 57% carbon loss pada penelitian ini telah teridentifikasi.

Abstract
Carbon loss by more than 65% was the major obstacles to the pilot-scale
production of CNTs using gauze reactor. Therefore in this study, to be identified by
analyzing the possible causes of carbon loss, such as error of product flow rate due to
measurement of bubble soap and possible of feed flow rate changes due to the catalyst
presence and the CNT growth in the reactor, analysis of product composition by GC FID
and analysis the possibility of particulate carbon in gas products was identified too by
using glass fiber filters. The results showed that the initial carbon loss calculation before
prior to be analized by the above method was much smaller than previous studies, namely
27.64%. This is because feed flow rate has been calibrated with the condition of the
reactor containing the catalyst instead of an empty reactor. Carbon loss will reach 69.14%
if the feed rate used in the calculation was calibration results when the reactor is empty.
This is because the catalyst in the reactor led to feed flow rate less 28% of the total
discharge current when the empty reactor. Product flow rate error due to measurement of
bubble soap give error in the carbon loss calculation up to ± 4.14%. Changes in feed flow
rate because the growth of CNTs in the reactor reduce the amount of carbon loss as much
as 4.97%. While the detection of secondary hydrocarbons by GC FID during CNT
production reduces carbon loss up to 5,41%. In addition, particulate matter carried by the
flow of products is very little and only give carbon loss corrected for 0.05%. Taking into
account all the factors above, the amount of carbon loss in this study were 16.23 ± 4.14%.
If we assume 4,14& carbon loss was caused by error occurred during the study, the
amount of carbon loss is 12.09%. This means that more than 57% carbon loss in this
study have been identified.
