Screening Of Tar Cracking Catalysts For Syngas Produced By Biomass Gasification, Bijeet Mukherjee
Screening Of Tar Cracking Catalysts For Syngas Produced By Biomass Gasification, Bijeet Mukherjee
LSU Master's Theses
The gasification of biomass produces tars and particulates. These tars and particulates create problems in the gasification systems. Tars condense on surfaces at lower temperatures, such as exit pipes and on particulate filters, leading to blockages and clogged filters. Tars also have varied impacts on other downstream processes. Due to these reasons, syngas containing significant concentrations of tars cannot be used in internal combustion engines. Thus the processes through which tars can be removed have been subject to considerable research. The objective of this research was to identify the best catalyst for for down-draft gasifiers, including the LSU AgCenter down-draft …
Assessing The Suitability Of Various Feedstocks For Biomass Gasification, Akshya Sharma
Assessing The Suitability Of Various Feedstocks For Biomass Gasification, Akshya Sharma
LSU Master's Theses
Ten different types of feedstocks available in Louisiana were assessed for their suitability to produce SYNGAS in a down-draft biomass gasifier. The feedstocks tested for this research include: pine pellets, hardwood pellets, cypress mulch, pine bark nuggets, corn stover pellets, switchgrass pellets, sugarcane bagasse pellets, dairy manure pellets, and poultry litter pellets. The feedstocks were first analyzed for volatile & ash content, high heating value, moisture, and mass density. Feedstocks that met the analytical criteria and available in a form that is suitable for the down-draft gasifier at LSU were tested for gasification. The temperature profile within the gasifier and …
