Cuphea oil

Crop description. Cuphea spp., C. carthagenensis, C. painter, C. ignea, and C. viscosissima—commonly known as cuphea—belong to the family Lythraceae and grow in temperate and subtropical climates (see Fig. 4.5). They can be found in Central and South America, and have been grown in trials in Germany and the United States. The seeds of Cuphea con­tain about 30-36% oil [69]. […]

Transesterification of vegetable oils by acid or alkali

Goering et al. [24] have suggested that vegetable oils are too viscous for prolonged use in direct-injected diesel engines, which has led to poor fuel atomization and inefficient mixing with air, contributing to incomplete combustion. These chemical and physical properties caused vegetable oils to accumulate and remain as charred deposits when they contacted engine cylinder walls. The problem of charring […]

Other Metal Oxide Catalysts

Cottonseed oil has been thermally decomposed at 450°C using 1% Na2C03 as a catalyst [42]. Pyrolysis produced a yellowish-brown oil with 70°C yield. The fuel properties of original and pyrolyzed cottonseed oil are sum­marized in Table 8.7. Results of ASTM distillation compared to diesel are given in Table 8.8 showing a higher volatility for the conversion product.
