Process development and deployment for the direct reforming of crude oil to hydrogen and carbon materials

Problem statement

Hydrogen is a clean energy source and carrier because of its non−polluting combustion, making it an excellent alternative to the current fossil fuel-dominated energy scenario. Nonetheless, there are several critical challenges to implementing a broad sustainable use of hydrogen. In this project, we develop a laboratory−scale setup with stable operation and high hydrogen production.

We aim at assessing (i) different hydrocarbon feedstock (from n-heptane to crude oil) fed to the reactor with water as emulsions, carried by steam or vaporized; (ii) steam reforming (SR) and auto thermal reforming (ATR); and (iii) stable and energy efficient catalysts for the efficient production of hydrogen inside packed, fluidized, and multifunctional reactors. These, coupled with carbon capture technologies, minimize the carbon footprint of the overall process.

We support our research with simulations and techno−economic analysis to assess the approach's feasibility. C2H can use the current refinery infrastructure to reduce costs and the impact of market volatility on refinery operations.

Goals

  • Develop and scale up advanced catalysts and reactors for converting crude to hydrogen
  • Model process simulations to analyze the viability of the process 
  • Scaling the technical catalysts for their demanding application: endothermic process, poisoning, massive coke deposition, and fluidized-bed reactors
  • Analyze different process conditions to optimize hydrogen production and stability in the process

Compositional Insights and Valorization Pathways for the Carbonaceous Material Deposited during Bio-Oil Thermal Treatment

Abstract

This work analyses the composition, morphology, and thermal behavior of the carbonaceous materials deposited during the thermal treatment of bio‐oil (thermal pyrolytic lignin—TPL). The bio‐oil was obtained by flash pyrolysis of lignocellulosic biomass (pine sawdust), and the TPLs were obtained in the 400–700 °C range. The TPLs were characterized by performing elemental analysis; 13C NMR, Raman, FTIR, and X‐ray photoelectron spectroscopy; SEM; and temperature‐programmed oxidation analyzed by differential thermogravimetry and differential scanning calorimetry. The results are compared to a commercial lignin (CL). The TPLs have lower oxygen and hydrogen contents and a greater aromaticity and structural order than the CL material. Based on these features, different valorization routes are proposed: the TPL obtained at 500 °C is suitable for use as a fuel, and the TPL obtained at 700 °C has a suitable morphology and composition for use as an adsorbent or catalyst support.
