GASIFICATION OF BIO-OIL AND ALKALI CONTAINING ENERGY RICH AQUEOUS SOLUTIONS FROM PULP MILLS

摘要

Process for gasification of an alkali containing energy rich aqueous solution (120) from a pulp mill in an entrained flow gasification reactor (2), the process comprising the steps of d) Supplying said alkali containing energy rich aqueous solution (120)to said gasification reactor (2), e) Gasifying said alkali containing energy rich aqueous solution (120) in the reactor (2) by using an oxidizing medium at sub-stoichiometric conditions and at a temperature below 1400C in an outlet of said reactor (2); and, f) Producing a phase of a liquid material and a phase of a gaseous material in said reactor (2). wherein in step (a) supplying a bio-oil (110) to said gasification reactor (2), in step (b) simultaneously gasifying said alkali containing energy rich aqueous solution (120) and said bio-oil (110) in the reactor (2).
