INTRODUCTION

The Environmental Control and Life Support Systems (ECLSS) at Marshall Space Flight Center (MSFC) has worked with Cooperative Agreement Notice (CAN) partners to identify alternative MOF candidates to act as a hydrogen separation technology to separate/capture hydrocarbons (acetylene, carbon monoxide, methane, and ethylene) from Methane Post-Processor Assembly (MPPA) off-gas.

Recovery of hydrogen will allow for increased overall efficiency and recyclability of Sabatier CO2 chemical reduction processes required for Mars Transit, Surface Habitat, and future long-duration flight missions away from Earth.

The Closed-Loop ECLSS Air Revitalization (CLEAR) Team is interested in a bulk synthesis of Cu[Ni(pdt)2] (NKMOF-1-Ni). NASA will defer to the expertise of The Commercial Partner to select one or two organo-ligand binder candidates. The organo-ligand binder candidates must be able to:

1. Withstand activation temperatures of at least 150°C.

2. Must not degrade in the presence of moisture (<1% H2O vapor by volume)

3. Must not introduce additional off-gas or dusting hazards (must not degrade).

4. Be compatible with a gas composition containing hydrogen, acetylene, ethylene, carbon monoxide, and methane.

The MOF(s) will be evaluated for their capability to separate hydrogen on a benchtop scale.

GOALS AND OBJECTIVES

The goal of this statement of work is to procure two 1-kg (±0.5 kg per pelletizing process) batches of pelletized MOF to test in the sub-scale test bed. The objectives of this statement of work are as follows.

1. Commercial Partner shall produce two 1-kg (±0.5 kg) batches of MOF including: 1-kg (±0.5 kg) of Cu[Ni(pdt)2] bound into spherical particles of sizes (8-12 mesh) using Binder 1 and 1-kg (±0.5

kg) of Cu[Ni(pdt)2] bound into spherical particles of sizes (8-12 mesh) using Binder 2 (if applicable)

a. Spherical shaping is selected as an optimal shape for packing.

b. Utilizing 1-kg (±0.5 kg) to reduce cost of production based on potential batch sizes available to the commercial partner.

c. Binder selection must be accompanied with justification and assurance that organo-ligand binder candidates meet the requirements in the Introduction.

2. Deliver to Marshall Space Flight Center.

Performance Requirements and Deliverables:

The Product Requirements are noted as follows:

1. Pelletized MOF shall be spherical or semi-spherical in structure.

2. MOF size shall be 8-12 mesh.

The Deliverables are as follows:

1. 1-kg (±0.5 kg) of pelletized Cu[Ni(pdt)2] bound with Binder 1

2. 1-kg (±0.5 kg) of pelletized Cu[Ni(pdt)2] bound with Binder 2
