Abstract
A reactor system may comprise a housing; and a condensation catalyst layer within the housing comprising a condensation catalyst comprised of at least one of a base-substituted zeolite, a stannous salt, or a phosphonitrile chloride. The condensation catalyst layer may be configured to catalyze a condensation reaction of a plurality of silane diols in water flowing through the housing into a plurality of siloxanes.
Claims11
A method, comprising:
- causing water and a plurality of silane diols to contact a condensation catalyst comprised in a reactor system, wherein the condensation catalyst comprises a phosphonitrile chloride;
- and
- reacting the plurality of silane diols with the condensation catalyst to form a plurality of siloxanes, wherein at least one of:
- the condensation catalyst further comprises a binder, or
- wherein the condensation catalyst is pelletized.

A fluid treatment system, comprising:
- an air conditioner comprising a heat exchanger, wherein the heat exchanger comprises a hydrophilic coating that condenses water and siloxanes out of air, wherein the hydrophilic coating and the siloxanes react to form a plurality of silane diols;
- and
- a reactor system fluidly coupled to the air conditioner downstream of the air conditioner, wherein the water and the plurality of silane diols, from the air conditioner, flow to the reactor system, wherein the reactor system comprises a housing and a condensation catalyst within the housing comprising a phosphonitrile chloride, wherein the water and the plurality of silane diols flow through the reactor and contact the condensation catalyst, which catalyzes a condensation reaction of the plurality of silane diols flowing through the housing into a plurality of siloxanes.
A method, comprising:
- causing water and a plurality of silane diols to contact a condensation catalyst comprised in a reactor system, wherein the condensation catalyst comprises a phosphonitrile chloride;
- reacting the plurality of silane diols with the condensation catalyst to form a plurality of siloxanes;
- condensing the water and a first plurality of siloxanes out of air onto a surface comprising a hydrophilic coating prior to the causing the water and the plurality of silane diols to contact the condensation catalyst;
- and
- forming the plurality of silane diols via a reaction between the hydrophilic coating and the first plurality of siloxanes.
