Re: [Biofuel] sustainable biodiesel from Casto : Big is not beautiful, small is more sustainable
Dear Bob and Keith I am very sorry for the late reply , not able to be as quick as KEITH>>>I interpreted this to mean that the crushed seeds are subjected to the alkali catalyst/methanol hence the seed cake is exposed to the reaction. Here in Brazil nobody like to use Methanol , yes you are correct that the crushed seed is used as feed stock.The mixture of this two methanol and ethanol can be better, but the process for the big scale use methanol , and there is also effort to make the carbohydrate to make ethanol in future.sdPannirselvam bob allen <[EMAIL PROTECTED]> wrote: By using one step simultaneous extraction and >esterification , the patented process use crushed seeds to make >four products , the BioD , the glycerol , the protein, carbohydrate >that seem to deintoxicated for animal feed is now being scaled up >to big pilot plant.I interpreted this to mean that the crushed seeds are subjected to the alkali catalyst/methanol hence the seedcake is exposed to the reaction.

Re: [Biofuel] sustainable biodiesel from Casto : Big is not beautiful, small is more sustainable
I understand that lubricity has to do with the ability of the oil to maintain a lubricating film under pressure. Viscosity has to do with how readily the oil flows. They are not related. An early detailed study of the properties of lubricants was done by Ricardo Engineering for the British Air Ministry in the 1920's. I'm sure there has been a lot done since.

Castor oilseed cake does make a good "fertiliser". A better way to do it would be to compost it, but the ricin will break down in the soil, there's no danger of your eating ricin with the crops subsequently grown there. By the time the crop roots get there it's not ricin anymore. Indian peasants have long known about many things that science has only belatedly discovered, there are many examples of it. Bad practices usually get sifted out when they don't meet the test of generations, but indeed not always, far from it. The wise and noble peasant is just as much of a myth as the dumb illiterate peasant is. Or rather they both exist.

Some of my friends here in India (who know more about agriculture than I do) would have me believe that traditionally castor oilseed cakes are allowed to decompose by soaking in a little water for a couple of weeks and then put back into the soil as fertilizer (same as done with mustard oilseed cakes). Apparently it is a very effective organic fertilizer and no ill effects seem to be manifest in the use of the resulting crops. I see no reason to blindly believe that traditional methods are always free of bad effects, however, I understand that castor is a native plant species of India, therefore this practice could well be thousands of years old.

Re: [Biofuel] sustainable biodiesel from Casto : Big is not beautiful, small is more sustainable
Respected and dear Keith and members Thanking you for you to bring here the updated valuable information about Castor as biofuel raw material. The underdeveloped dry semiarid land of the north east of Brazil has been found to be very excellent for Castor cultivation with high productivity. .The Brazilian big oil company PETROBRAS has pa tended process based on the Castor , some more detailed process information , I can send another e mail if there is an need for the same here. By using one step simultaneous extraction and esterification , the patented process use crushed seeds to make four products , the BioD , the glycerol , the protein, carbohydrate that seem to deintoxicated for animal feed is now being scaled up to big pilot plant. Competing with this big , another big a private oil company , now making investments with social and unfriendly agricultural modern big farming , as this company called Eco diesel is also entering now into the market of Brazilian B2 fuel market, making sound Eco farming model giving land for the poor landless peole to plant Castor , the housing , the eduction ,the state government giving the lands , this private company use the conventional process based on the process of the Brazilian father of BioD , Prof Expedito Parente , who invited me from India to BRAZIL(1983) , for me to dedicate on the the Brazilian biofuel research project. He has the first word patent of bioD including the Castor based process , and also made Biokerosene from castor oil sucessfully proved to be the fuel for airoplane with Military research. Prof Expedito also work with several government and private company to make Biofuel and any one can easily share experience with him about castor oil processing and he has book published too in Brasil The small presss , the small JTF procees , designed to make animal feed , pyrolsed biogas , Biofuel and organic fertlizer to recycle back the bioenrgy for comunity development is our small group research efforts which surely include sunflower , caster oil of the dry lands as these can make sustainable the life of dry semiarid peple with great hope with green energy projects.This integrated project is our dream to make it reality , as we have already made the small press , thanks to Keith JTF , so simple to make , now processing coonut , getting good resutls , future the sunflower and also the castor oil . We believe , there is no need of bioD , as we already can use oil directly upto 25 porcent by blending with petro deisel as this is very cheaper in rural area too , the blending of BIOD from caster , we hope to get the better results . Brazil has 20 years of good research reports about castor oil use as biofuel , which we have the acess .One main problem with castor oil BioD is the viscosity that can be easily solved. We are ready to shar the the Brasilian research effort as we believe that we will be the number one in the world to come up with this biofuel , not because of the will of the 8 biilions of liters of alcohol we produce , because the country has the vast land resources nearby by the Africa , and Europe where there is need for the fuel . Yet big is not not beautifuel , as Micro Soft Bill Gate too has invested the money in the big Brazilian ethanol plants , but what we need is a sustainable global world based on small scale decentralised biomass refinary and investments for small ecobusiness , not the money of big blues for the modern high tech , leading to large scale unemployments and large loans , poverty. In this respect our biofuel list members are more aware , yet we need to come together , give and take our hands to solve the problems , mainly the from tropical south countries with the need to duplicate the big scale BIOD busines mistake of the developed countries as other need not blindly copy the Big one HIGH TECH .
