Super cetane

The production of super cetane by direct hydrotreatment of natural triglycerides can, in principle, significantly reduce the operating costs of converting triglycerides to diesel fuel substitutes. The process is less complex than transesterification, as illustrated by the basic operations of the processing sequence shown in Fig. 10.6. Conventional refinery processing is used to produce a... 

An economically attractive approach to commercial production of diesel fuel substitutes from natural biomass liquids in North America appears to be the direct conversion of waste biomass oils to super cetane by catalytic hydrotreatment. This technology is expected to be commercialized first in Canada where it was developed. The availability of large amounts of feedstock... 

There is a need to seek an environmentally benign, technically feasible and economical alternative fuel because of the limited crude oil reserves and serious pollution all over the world. Recently, dimethyl ether (DME) is proved to be used as an alternative clean fuel in transportation, power generation and household use for its excellent behavior in compression ignition for combustion, cetane number of over 55 and zero sulfur content, and is praised as a super-clean fuel in the 21 century. It has a promising foreground of application. Therefore, the efficient synthesis of DME from syngas derived from natural gas, coal or biomass has drawn much attention.
