The increased production of coconut has by the shell produced, even though this lignin content 33.30% so it potential to be converted into charcoal through pyrolysis process. Pyrolysis is a thermal decomposition process that occurs without air or with little convert biomass charcoal. Coconut can used for coal co-firing in developing new and renewable energy. This study aimed obtain best tempera...

Abstract In order to study the flame propagation characteristics and influencing factors of gas-coal dust mixed explosion in containers, this paper quantitatively explores effect mechanism two-phase concentration ratio closed section restraint mode on coupling by numerical simulation, comprehensively considering coal pyrolysis model mass heat transfer model. The current research results show th...

Abstract Tapioca industrial solid waste is a very abundant and high cellulose content that makes from tapioca an alternative material substituted to coal. The low-calorie value of around 2783 Kcal/kg, which requires effort increase calorie value—increasing the by carbonization in pyrolysis furnace. study with replace coal improve similar commercial needs be done. In this study, influence time t...

This thesis consists of uncertainty and techno-economic studies of two different biofuels production pathways (catalytic pyrolysis and gasification). The objective of this paper is to obtain a side-by-side techno-economic comparison of in situ and ex situ catalytic pyrolysis, and gasification state-of-technology and target scenarios that addresses both sensitivity and uncertainty analysis in th...
