Life cycle assessment (LCA) has been widely used to analyze various pathways of biofuel preparation from “cradle to grave.” Effects of nitrogen supply for algae cultivation and technology of algal oil extraction on life cycle fossil energy ratio of biodiesel are assessed in this study. Life cycle fossil energy ratio ofChlorella vulgarisbased biodiesel is improved by growing algae under nitrogen-limited conditions, while the life cycle fossil energy ratio of biodiesel production fromPhaeodactylum tricornutumgrown with nitrogen deprivation decreases. Compared to extraction of oil from dried algae, extraction of lipid from wet algae with subcritical cosolvents achieves a 43.83% improvement in fossil energy ratio of algal biodiesel when oilcake drying is not considered. The outcome for sensitivity analysis indicates that the algal oil conversion rate and energy content of algae are found to have the greatest effects on the LCA results of algal biodiesel production, followed by utilization ratio of algal residue, energy demand for algae drying, capacity of water mixing, and productivity of algae.

Abstract Agriculture and forestry remain the leading sectors in Cameroon, accounting for some 36% of the merchandise exports and for more than 40% of GDP in 1998/99. Agriculture alone accounts for more than 30% of GDP and provides employment for about 68% of the active population. The Cameroon government and industry stakeholders have continuingly expressed concern about the impact of rising food import on the local industries and the rural communities especially as vegetable oils, particularly the palm oil, has a vital role to play not only as nutritional source for the Cameroon population, but for their contribution to rural incomes and employment opportunities. Particularly, Cameroon government is expecting a significant progress in implementation of new oil extraction technology where mainly in the palm oil processing technology the value added chain in this commodity is expected. Cameroon’s oil palm industry still plays a significant role in the national economy, providing oil for house hold consumption, industrial use as well as employment for thousands of Cameroonians who are engaged in production, processing and marketing. This project aims at bringing clarity on to what extent the up to date oil extraction processing technology installed in a concrete rural district, and under a clear management and regulatory structure and environment, outperforms in terms of productivity (tons of palm oil produced), quality (price of the crude palm oil) and income generation, the existing traditional manual processing palm oil producing system. The methodology applied within this study consists of comparing key indicators across populations of small scale palm oil processors in interaction with traditional non sophisticated technology with different work environment, production capacity, socio-economic status and income levels (cross-sectional statistical analysis)

Electrical Submersible-motor-driven Progressive Cavity Pumping (ESPCP) oil extraction technology has the advantages of sample technology and management convenience. ESPCP is suitable for the viscous, containing sand, high gas oil ratio oil extraction. Developing history of ESPCP is introduced and the structure and principle are analyzed. The advantages of ESPCP are compared with other oil extraction technology. At last, developing status is discussed and the developing trend is investigated.

The objective of this paper was to separate curcumine from Rhizoma curcuma longae and aqueous two-phase extraction technology was employed to perform the study. Four types of PEG (400, 600, 2000 and 4000) and three types of salt ((NH4)2SO4, KH2PO4 and K2HPO4) were tested to form the aqueous two-phase systems. The results showed that the ATPS composed of PEG 400 and (NH4)2SO4 were the best. And the partition coefficient of curcumine could reach 21.79 when the concentration of PEG 400 and (NH4)2SO4 was 14.6% and 26% respectively.
