• campus Alert ✖CLOSE

    #BraveNation:

    Yesterday evening Piedmont Natural Gas disconnected natural gas service to main campus in order prevent potential hazards. As of this morning, gas service has not been restored. Utility crews are working continuously to repair the segment and restore service as soon as possible.

    It is important to know faculty, staff, students and visitors on campus are not in immediate danger because of any potential gas leaks. The disruption in service may affect some campus activity throughout the day, including dining services. Dining facilities are working to bring in the necessary resources to provide limited hot meal options. We appreciate your patience and will update you as additional information becomes available.

Catalysts

A number of different catalyst systems can work for the conversion of oils or fats (fuelstock) into biodiesel. Among the options are either acidic or basic homogeneous catalysts or acidic or basic heterogeneous catalysts. Homogeneous catalyst systems require catalysts which are liquids and heterogeneous catalysts are solids.

Basic catalyst:

KOH – Potassium Hydroxide

NaOH – Sodium Hydroxide

Choline Hydroxide – phase transfer catalyst

TMAH – phase transfer catalyst

Acidic Catalyst:

Excess methanol and sulfuric acid H2SO4

Solid resin acids
