Dear Dr. Vis,

I am a master degree student and very interest in marine fuels subjects and also biofuels.

I would like to ask you some questions:

1) Is there any prohibition in the use of biofuels (biodiesel, animal tallow etc.)?

2) What are the difference between RMG 380. RMK 380 and RMH 380? Besides of course the density, carbon residue and vanadium values...

3) Is there any problem in use oxygenates in marine fuels such as ethanol or glycerin etc. ?

I would appreciate to have your answer to these questions.

Thanks in advance.

Antonio
