AI Technical Summary

Benefits of technology

The sorbents effectively capture contaminants, reducing waste production, lowering production costs, and enhancing fuel quality evaluation, outperforming commercial sorbents in glycerol and surfactant removal from biodiesel.

Problems solved by technology

Currently, use of dry wash media for cleaning biodiesel is largely limited to small operations and hobbyists.

Abstract

Mesoporous organosilica sorbents are effective to remove contaminants (such as glycerol or detergent) from biodiesel. Contacting biodiesel with various a mesoporous organosilica sorbents comprising phenyl and sulfonate moieties resulted in the contaminants being absorbed by the sorbent and thus removed from the biodiesel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application claims the benefit of U.S. Provisional Application 62 / 314,577 filed on Mar. 29, 2017, the entirety of which is incorporated herein by reference.BACKGROUND[0002]Biodiesel is produced by transesterification of animal fat, vegetable oil, or waste cooking oil with an alcohol, producing the desired biodiesel fuel along with glycerol as a byproduct. A number of studies have focused on the evaluation of the economic viability of biodiesel.2-5 Production costs are approximately 0.5 USD / L, 1.5 times that of petroleum-based diesel, with virgin feedstocks comprising 50 to 70% of costs.3,4 The feedstock costs can be reduced through the use of waste cooking oils and similar products, but these materials increase the complexity of synthesis and, often, the presence of contaminants.5 In addition to providing a renewable source of energy, biodiesel is attractive as an alternative fuel due to related reduced environmental impact; use of t...
