I do not know how efficient it will be, but if you have a range for your operational temperature, I would suggest to start from a low temperature in order to avoid agglomeration problems. Algae tends to have a very high ash content and this makes it challenging for thermochemical conversions. Check for agglomeration indicators, such as (Na + K)/ (2S + Cl) > 1.
Dear Dr. Deorgios thank you so much for your suggestions. Actually I am concern about it's "Protein" content. Being rich in protein content >60%, how it will contribute to gasification or how this big portion of protein would be helpful for hydrogen production via gasification???
