Waste cooking oil (WCO) is a kind of non-edible oil with enormous quantities and its unreasonable dispose may generate negative impact on human life and environment. However, WCO is certainly a renewable feedstock of bio-based materials. To get the rebirth of WCO, we have established a facile and high-yield method to convert WCO to bio-based zwitterionic surfactants with excellent surface and i...

A total of 1,480 pigs were used in 3 experiments to determine the effects of corn distillers dried grains with solubles (DDGS) varying in oil content on growth performance, carcass traits, and nutrient digestibility in finishing pigs. In Exp. 1, 1,198 pigs (PIC Line 337 × 1050; initially 46.1 kg) were allotted to a corn-soybean meal-based diet or diets with 20 or 40% of a 5.4% oil DDGS (29.5% C...

This paper presents the definition and implementation of a CORBA-based system for the distributed monitoring of automated oil wells located in on-shore petroleum fields. Conducted by the automation of industrial processes in the oil and gas area, the development of computational distributed systems, based on emerging middleware technologies and designed to monitor and actuate in such particular...

Regional crops distribution is an import subject for developing modern agriculture now. Based on existing distribution of 7 grain and oil crops in Sichuan province, this paper chose 5 economic evaluation indexes to discuss the regional distribution of grain and oil corps in Sichuan with the method of grey situation decision. According to the row decision and column decision, this paper shows th...

In this paper the transesterification of palm oil with methanol in the presence of NaOH as a catalyst was conducted in an experimental biodiesel installation. The kinetics of base-catalyzed transesterification of palm oil based on parameters such as oil and alcohol ratio, catalyst concentration and temperature were investigated to optimize the biodiesel production rate. Although, transesterific...

The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based o n the fresh weight. The oil was an alysed by capillary GC and GC– MS. Thirty seven constituents, representing 97.81 % of the o il were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lav...

In previous laboratory study, we have shown the thermal behavior of Keke Ya light crude oil Tarim oilfield, branch of CNPC for high-pressure air injection HPAI application potential study. To clarify the influences of thermal effects on oil production, in this paper, we derived a mathematical model for calculating oil flow rate, which is based on the heat conduction property in porous media fro...

The performance of air conditioner and the reliability of compressor could be reduced, if the refrigerant gas is discharged from compressor with excessive lubricating oil. Thus, the study of the reduction of the oil circulation rate in the compressor is required to resolve the problem. In this paper, five feasible approaches to decrease the oil circulation rate were confirmed by experiment. the...
