Process of Bio-Diesel Production from Camelina Oil

Here is the results of a project conducted by researchers at Crops Research Centre, Oak Park, Ireland. The aim of the project was to examine the potential of alternative vegetable oils, oil wastes or animal fats as bio-diesel feedstocks, and the performance of road vehicles using bio-diesel blends made from these materials. Three feedstock materials were considered: waste cooking oil from the catering industry, Camelina oil, and beef tallow.

They have showed that the oil yield from Camelina sativa is similar to that of rape, but it requires lower fertiliser and pesticide inputs, which leads to a lower cost and a more favourable energy ratio.

They have also provided the low-temperature properties of blends of waste cooking oil ester and mineral diesel( refer the following table).The ester yields for camelina oil were higher than for waste cooking oil. The fuel properties of the methyl ester were also within specifications with the exception of cold filter plug point (CFPP).

Camelina ester %	Mineral diesel %	Cloud point oC	CFPP oC	Pour point oC
100	0	+3	-3	-4
80	20	+3	-7	-6
60	40	+3	-9	-9
40	60	+3	-11	-12
20	80	+3	-13	<-18
0	100	+3	-15	<-21
