Embodiment Construction

[0020] Embodiments disclosed herein generally relate to methods and apparatus for simultaneous production and separation processes. The apparatus provides a membrane assembly including a substrate, a catalytic membrane and a membrane layer. The catalytic membrane includes nano-sized particles that enable the device to operate in sulfur-free and sulfur-containing feed gas environments for WGS reactions while maintaining high reaction conversion. Embodiments described herein also include methods for forming sulfur-tolerant nanocatalysts suitable for gas-to-gas or gas-to-liquid simultaneous generation and separation processes.

[0021] As used herein, the term "palladium (Pd) layer" generally refers to and may include a layer comprising palladium, palladium-containing particles, or a palladium alloy layer and / or particles. For example, the palladium layer can be a palladium transition metal alloy. Transition metals used to form palladium alloys may include gold, silver, aluminu...

Abstract

Embodiments disclosed herein generally relate to methods and apparatus for simultaneous generation and separation processes. The apparatus provides a membrane module including a substrate, a catalyticlayer and a membrane layer. The catalytic layer includes nano-sized sulfur-tolerant catalysts and / or particles. As a result, the apparatus can operate in sulfur-free and sulfur-laden (sour gas) environments for water gas shift (WGS) reactions while maintaining high reaction conversion. Methods for forming catalytic films are also disclosed herein. In one embodiment, methods of forming lanthanidecontaining oxysulfate nanocatalysts are provided.

Description

technical field [0001] Embodiments described herein generally relate to methods and apparatus for simultaneous production and separation processes. More specifically, embodiments include membrane reactors for use in equipment for gas-to-gas or gas-to-liquid simultaneous generation and separation processes. Also described herein are embodiments describing methods for forming nanocatalysts that can be used in simultaneous production and separation processes. Background technique [0002] Coal and natural gas resources are expected to provide greater than 40% of global energy demand over the next two decades. In order to mitigate global warming by reducing greenhouse gas emissions from power plants, industry, transportation, etc., advanced technologies are being developed to enable the clean, efficient and environmentally friendly use of these energy sources. As one of the advanced conversion technologies, coal gasification provides an efficient and flexible way to utilize ab...
