Para-xylene Selective Membrane Reactor

The current approach to p-xylene production includes an isomerization step that gives a nearly equilibrium distribution of mixed xylenes, followed by a separate step to recover p-xylene, then recycling of p-xylene depleted product for further isomerization. This project aims to develop and validate para-xylene ultra-selective zeolite membranes and integrate them with an appropriately designed isomerization catalyst in a membrane reactor to accomplish selective para-xylene production.

Dynamic Intensification of Chemical Processes

A significant portion of commodity productsare manufactured in large facilities that operate at steady state. In many ways, the traditional chemical industry has reached a plateau in terms of productivity and energy efficiency in such facilities. Improvements based on existing technologies and unit operations are mostly incremental and unable to address fundamental transport limitations that drive process efficiency.

Manufacturing Supply Chain Development for the STARS Technology Modular Solar-Thermochemical Conversion Platform

This project is looking to address the primary challenge we see in the module manufacturing space – how we can significantly improve the Manufacturing Readiness Level (MRL) of a high Technical Readiness Level (TRL) technology to open the door for broad deployment. In particular, the team at PNNL and OSU is carrying out a cost/manufacturability study on the piloted STARS technology for solar steam methane reforming.

Autothermal pyrolysis of lignocellulose wastes to sugars and other biobased products

Deconstruction of lignocellulosic biomass into fermentable sugars is among the major challenges in producing cellulosic biofuels and biobased products. Current pretreatment methods to liberate solid cellulose are expensive, accounting for as much as 30% of the cost of producing cellulosic biofuels. Most pretreatments do not completely fractionate cellulose and lignin, the latter of which interferes with enzymatic hydrolysis.
