Abstract
Biodiesel is an alternative fuel produced by a process known as transesterification of waste cooking oil. The chemical process reacts potassium hydroxide, methanol, and triglycerides. Triglycerides are found in many feedstock oils such as waste vegetable oil. California State University Sacramento (CSUS) has a production system on campus that converts waste cooking oil into biodiesel. The university has collaborated with the Sacramento Biofuels Network (SBN) to test and produce biodiesel that adheres to ASTM D6751 standards. The ASTM characteristics focused on in this study refer to cloud point, pour point, and corrosion strip test. The SBN fuel was utilized to develop standardized tests for these characteristics and used as baseline values for future production. The corrosion strip test resulted in a standard classification number of 2a, which is below the ASTM specification. The cloud point and the pour point were found to be -3.9℃ and -9.7℃, respectively.
