Natural gas enhanced biomass to liquids: Project development and modeling

Multi-fluid reactive modeling of fluidized bed pyrolysis process

“…Pyrolysis is one of the significant processes for producing energy from biomass (Chakravarti et al, 2012), where a set of thermo-chemical decomposition processes are used to convert the organic materials in biomass into carbon-rich solid and volatile matters by heating in the absence of oxygen (Demirbas and Arin, 2002). The solid content of pyrolysis products is known as the biochar or char, and is generally high in carbon content.…”

High temperature thermochemical processing of biomass and methane for high conversion and selectivity to H2-enriched syngas

“…The total number of unit operations is minimized and blending occurs before the inlet of the primary reactor. Studies that include process design show similar results to parallel configurations: increased product yields, carbon-to-fuel conversion, and energy efficiency all with the added benefit of reduced operational greenhouse gas emissions [8,23,25,27,28]. Sudiro and Bertucco studied configurations that included heat contributions from concentrated solar energy in an indirectly heated reactor design [29], representing one of the few attempts to incorporate an externally heated gasifier.…”

“…For gasification-based processes where at least one of the target products was liquid fuels, there are three conceptual configurations to convert natural gas and biomass (or coal) to syngas: parallel, sequential, and co-feed. In all scenarios there is remarkable improvement on carbon conversion and liquid fuel yield compared to conventional gasification processes [22][23][24][25][26].…”

Synthesis of augmented biofuel processes using solar energy

“…Alternatively, the identified augmented biofuel processes can operate round the clock by integrating with renewable energy storage systems . In a transition scenario, coal and natural gas can supplement biomass during times of solar energy unavailability …”
