Greeting to our dynamic leader of our list , Keith
Thank you for your quick reply
Because we have used vegetable oil , all going here as waste, we are
interested in this to make solid gel fuel.How to do so is the real
question .Some one can give new ideas as our group is really very big
and have expert in this field.
Cellulose powder can absorb oil and hence can help to be mixed
with the gel.solid that have been already made as solid mixing is
not the problems, but the .liquid mixing is the problems.
Eventhough solubility of vegetable oil is good , this may or may
not allow the gel formation .Only practical experiments can do the
help.
