Pengaruh Laju Alir Nitrogen Terhadap Yield dan Komposisi Bonggol Jagung Hasil Torrefaksi = Effects of Nitrogen Flowrate on Yield and Composition of Torrefied Corn Cobs
" ABSTRAK
Penelitian torrefaksi bonggol jagung telah dilakukan untuk mempelajari pengaruh laju alir nitrogen terhadap yield dan komposisi bonggol jagung yang dihasilkan melalui proses torrefaksi. Pengaruh laju alir nitrogen diteliti dengan memvariasikan laju alir nitrogen sebesar 0,3 L/min, 0,5 L/min, dan 0,7 L/min dengan masing-masing variasi laju alir nitrogen dilakukan pada 3 variasi suhu torrefaksi, yaitu 250oC, 275oC, dan 300oC. Proses torrefaksi berlangsung di reaktor tubular dengan holding time 20 menit, heating rate 10oC/menit, dan total ... "

A study of characteristics of palm oil biomass by using torrefaction process
" ABSTRAK
This research aims to study on the impact of temperature, reaction time and particle size of biomass on the property of calorific value in 3 types of raw biomass including palm branches, balm fibres and palm shell, and to forecast the calorific value equations to study the impacts of palm branch, palm fibre and palm shells calorific values. The experiment was carried out by grinding all raw biomass to be sized of 3 mm with ... "

Effect of heating rate of torrefaction of sugarcane bagasse on its physical characteristics
" Torrefaction, which is used to improve the properties of sugarcane bagasse as fuel in pulverised fuel combustion and as carbon feed in gasification, is a low heating rate pyrolysis of biomass carried out at a temperature of 200–300oC, at an atmospheric pressure, and in an inert environment. In the present work, sugarcane bagasse was torrefied at heating rates of 3, 6, and 10oC/minute, respectively, to achieve a final temperature of 275oC and after the final ... "

Investigation into the effects of torrefaction on the quality of pyrolysis products
" Interest in using biomass energy as an alternative to fossil fuels has advanced in recent years. This study aimed to assess the effects of torrefaction on the quality of pyrolysis products. Oil palm biomass, such as empty fruit bunches (EFB), mesocarp fiber (MF) and palm kernel shell (PKS) were either untreated (untorrefied) or torrefied (treated), and subsequently pyrolyzed. The experiment’s conditions for torrefaction were set to be a 220°C temperature, a 10°C/min heating rate, and ... "

Pengaruh laju pemanasan dan waktu penahanan suhu proses torefaksi terhadap karakteristik fisik biomassa ampas tebu = The effects of heating rate and hold time of torrefaction on sugarcane bagasse physical characteristics
" Deposit ampas tebu di Indonesia yang mencapai 8,5 juta ton per tahun menjadikan biomassa ini potensial untuk dikembangkan sebagai sumber energi alternatif. Perbaikan sifat ampas tebu sebagai bahan bakar padat dilakukan dengan torefaksi, yaitu proses pretreatment termokimia terhadap biomassa yang dilakukan pada suhu 200?300oC, tekanan atmosfer, dan lingkungan yang inert. Ampas tebu ditorefaksi sampai suhu 275oC dengan variasi laju pemanasan sebesar 3, 6, dan 10oC/menit dan variasi waktu penahanan suhu selama 0 dan 15 menit. ... "
