Hybrid and single feedstock energy processes for liquid transportation fuels: A critical review

Abstract This review provides a detailed account of the key contributions within the energy communities with specific emphasis on thermochemically based hybrid energy systems for liquid transportation fuels. Specifically, the advances in the indirect liquefaction of coal to liquid (CTL), natural gas to liquid (GTL), biomass to liquid (BTL), coal and natural gas to liquid (CGTL), coal and biomass to liquid (CBTL), natural gas and biomass to liquid (BGTL), and coal, biomass, and natural gas to liquid (CBGTL) are presented. This review is the first work that provides a comprehensive description of the contributions for the single-feedstock energy systems and the hybrid feedstock energy systems, for single stand-alone processes and energy supply chain networks. The focus is on contributions in (a) conceptual design, (b) process simulation, (c) economic analysis, (d) heat integration, (e) power integration, (f) water integration, (g) process synthesis, (h) life cycle analysis, (i) sensitivity analysis, (j) uncertainty issues, and (k) supply chain. A classification of the contributions based on the products, as well as different research groups is also provided.

Optimal energy supply network determination and life cycle analysis for hybrid coal, biomass, and natural gas to liquid (CBGTL) plants using carbon-based hydrogen production

A mixed-integer linear optimization formulation is developed to analyze the United States energy supply chain network for the hybrid coal, biomass, and natural gas to liquids (CBGTL) facilities. Each state is discretized into octants and each octant centroid serves as a potential location of one facility. The model selects the optimal locations of CBGTL facilities, the feedstock combination, and size of each facility that gives the minimum overall production cost. Two case studies are presented to investigate the effects of various technologies and hydrogen prices. The CBGTL network is capable to supply transportation fuel demands for the country at a cost between

Energy Supply Chain Optimization of Hybrid Feedstock Processes: A Review

Abstract A thermochemical based process superstructure and its mixed-integer nonlinear optimization (MINLP) model are introduced to convert biomass (switchgrass), coal (Illinois #6), and natural gas to liquid (CBGTL) transportation fuels. The MINLP model includes simultaneous heat and power integration utilizing heat engines to recover electricity from the process waste heat. Four case studies are presented to investigate the effect of CO 2 sequestration (CCS) and greenhouse gas (GHG) reduction targets on the process topology along with detailed parametric analysis on the role of biomass and electricity prices. Topological similarities for the case studies include selection of solid/vapor-fueled gasifiers and iron-catalyzed Fischer-Tropsch units that facilitate the reverse water–gas-shift reaction. The break-even oil price was found to be
