Quantitative analyses of products and rates in polyethylene depolymerization and upcycling

Recent publication from members in our group detail techniques for product recovery of polyethylene depolymerization, characterization and quantification of hydrocarbon products in complex mixtures, quantitative analysis of reaction selectivity for alkanes versus aromatics, and enumeration of depolymerization rates using average rates of C–C bond scission.

Recent publication from the Scott Group demonstrates improvement in their innovative process that turns polyolefins into high-value alkylaromatics. 

In the original process of turning polyethylene into long chain alkylaromatics, the platinum on alumina catalyst was slow and the yield of products low. In the improved process, the speed and selectivity of the reaction is enhanced by increasing the acidity of the alumina via the addition of chlorine or fluorine.

Current Initiatives

Mellichamp Initiative in Sustainability

Sustainable Materials and Product Design

In 2014, Susannah Scott created the interdisciplinary Mellichamp Academic Initiative in Sustainable Materials and Product Design, in order to integrate broader sustainability considerations into research in the chemical sciences
and engineering. UC Santa Barbara provided the Initiative with a cluster of
four endowed Chairs. The Initiative’s scope includes assessment/minimization
of environmental impact and assessment/optimization of economic feasibility, cultivation of public awareness, and social acceptance of sustainability goals. Susannah Scott currently holds the Mellichamp Chair in Sustainable Catalytic Processing.

Enhancing Success in Transfer Education for Engineering Majors

ESTEEM is an NSF-funded S-STEM scholarship program for academically-talented, low-income undergraduate students in Engineering. Led by Susannah Scott, the project is a partnership with Professor Mike Gerber in UC Santa Barbara's Gevirtz Graduate School of Education, and collaborators in four of our regional California Community Colleges (CCCs): Allan Hancock College, Oxnard College, Santa Barbara City College, and Ventura College. The goal is to facilitate transfer of engineering students between community college and four-year universities, understand barriers, promote their academic and professional success, and strengthen ties between CCC and UC faculty.
