Patent number: 10981785Abstract: The invention relates to an installation (1) and a method allowing the near total recovery and space-saving storage of carbon in the form of liquid carbon dioxide (19), from a substance (9) of the group consisting of hydrocarbons/ethers/alcohols, without the use of gas compression. To achieve this, a superheated gas (12) at a pressure of over 5.18 bar is generated from the substance (9) of the group consisting of hydrocarbons/ethers/alcohols and water (10), and this gas is delivered, by means of steam reforming and hydrogen liberation, into a retentate mass flow (15) containing carbon dioxide. Liquid carbon dioxide (19) is obtained therefrom by means of condensation, and is stored in a storage tank (7) while the liberated hydrogen is oxidised to provide mechanical and/or electrical as well as thermal energy. The use of membranes with low hydrogen/carbon dioxide permeation selectivity is permitted by forming a permeate mass flow circuit that is closed in respect of carbon dioxide.Type: GrantFiled: April 28, 2017Date of Patent: April 20, 2021Inventor: Christian Mair

Patent number: 10967363Abstract: Metal-support interaction offers electronic, geometrical and compositional effects to tune and maneuver catalytically active sites. Here we report the first example of a reactive metal support interaction (RMSI) between Pt and various MXenes, which are two-dimensional (2D) metal carbides, nitrides, or carbonitrides. The invention thus provides intermetallic Pt/MXene nanoparticle catalysts comprising platinum and MXene moieties. Pt3Ti and Pt3Nb intermetallic nanoparticle catalysts were prepared by RMSI of Pt nanoparticles supported on Ti3C2 and Nb2C MXenes. The intermetallic structures were verified by XAS, ARSTEM, and XPS. Experimental analysis showed that the extent of alloy formation is temperature dependent. Kinetics analysis revealed that in contrast to Pt/Al2O3, Pt supported by Nb2CTx exhibits weaker CO adsorption and the alloy-MXene interface shows enhanced ability of H2O dissociation for a water gas shift (WGS) reaction at 300° C.Type: GrantFiled: October 16, 2018Date of Patent: April 6, 2021Assignees: Iowa State University Research Foundation, Inc., Purdue Research FoundationInventors: Zhe Li, Yue Wu, Jeffrey T.
