No, it isn't. You don't do research on a scheduled airliner with paying pax. Research is done by engine manufacturers in engine test cells or on test aircrafts.
If you have biofuel fulfilling Jet A specs, then you just fill and go full steam overnight. Problem is that there is no such fuel available in any significant quantity.
Problems with biofuel are not on the consumer side, they are on the production side - that's where research is needed.
If we would replace present day consumption of fossil fuels with biofuels, using mature technology, and without starving a few billion people to death, then we need a couple of new Earth like planets to grow it.
Algae and the oceans are the only things which offer the scale needed, but the technology isn't there (yet).
As long as we cannot produce 100% biofuels, then it is pretty insane to spend a lot of energy on making the little we have into Jet A specs instead of using its full energy potential in less hi-tech applications such as domestic heating or electric power production.
