Methanol recovery during transesterification of palm oil
High quality palm oil biodiesel can be produced by combination of alkali transesterification and separation processes in a TiO 2 /Al 2 O 3 membrane reactor. Due to the small molecular size, methanol molecules are able to pass through the membrane along with the products.

TRANSESTERIFICATION OF PALM OIL: EFFECT OF REACTION
TRANSESTERIFICATION OF PALM OIL: EFFECT OF REACTION PARAMETERS methanol-to-RBD palm oil of 15.6:1, catalyzed by NaOH (0.75 wt% based on the oil used) and a stirring speed of 600 rpm. Effect of water in transesterification of palm oil. Transesterification was carried out on RBD palm oil (200 g) with methanol (95 ml) catalyzed by NaOH
High quality palm oil biodiesel can be produced by combination of alkali transesterification and separation processes in a TiO2/Al 2O3 membrane reactor. Due to the small molecular size, methanol molecules are able to pass through the membrane along with the products. Since methanol is one of the process reactants it is necessary to be recovered

(3) Transesterification reaction: The pretreated oil and methanol, together with a small amount of NaOH as a catalyst, transesterification reaction at a certain temperature and atmospheric pressure, that can produce methyl ester, two-step reaction, through a specially designed separator to continuously remove the glycerol generated in the
Another study reported the synthesis of methyl or ethyl esters with 90% yield by reacting palm and coconut oil from the press cake and oil mill and refinery waste with MeOH or EtOH in the presence of easily available catalysts such as ashes of the waste of these two oilseeds (fibers, shell, husk), lime, zeolites, etc. Similarly, it was reported
Used and Waste Oil and Grease for Biodiesel Edible Oil
Some of the most environmentally friendly biodiesel feedstocks are used cooking oil and waste grease. According to the EPA’s Renewable Fuel Standards Program Regulatory Impact Analysis, released in February 2010, biodiesel produced from waste grease results in an 86% reduction in greenhouse gases, compared to petro-diesel. There are two general categories of waste oil and grease.
Through continuously inleting methanol gas in the reaction process, the water in the reaction is continuously vaporized to enter the methanol recovery column and recycled, the mixed material is reacted with the superheated methanol in the reactor without mechanical stirring, and the reaction time is controlled in 3.5~4h.

Biodiesel Production from Crude Palm Oil
INTRODUCTION. Biodiesel is the mono-alkyl esters of long-chain fatty acids derived from vegetable oils (palm oil, rapeseed, soybean, etc.) as well as animal fats. Biodiesel synthesized from the triglycerides in vegetable oils by transesterification reaction with alcohol.
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification.This involves vegetable or animal fats and oils being reacted with short-chain alcohols (typically methanol or ethanol).The alcohols used should be of low molecular weight. Ethanol is the most used because of its low cost, however, greater
