Abstract: A process for the production of a liquid lignin composition, in particular to a method for obtaining a lignin composition using a compressed gas and acid assisted process, wherein a lignocellulosic biomass feedstock is treated with a polar organic solvent using an inorganic acid to assist in the release of lignin into the polar organic solvent and the use of compressed gas to keep the polar organic solvent in its liquid phase.

Abstract: A composition including a heavy petroleum oil and a lignin oil containing lignin oligomers and methylated sugars.

Abstract: A process the production of a crude liquid lignin oil (CLO), the process includes the steps of providing a lignin-rich solid feedstock and subjecting the lignin-rich solid feedstock to a treatment in a polar organic solvent in the absence of an effective amount of added reaction promoter, such as a heterogeneous and/or homogeneous catalyst and/or hydrogen, and providing a lignin composition, the treatment includes a step of contacting the lignin-rich solid feedstock with a polar organic solvent under operating conditions of an operating temperature up to 210° C., an operating pressure lower than 50 bar and a residence time up to 240 minutes, wherein the ratio (w/v) of lignin (in lignin-rich feedstock) to polar organic solvent ranges between 1:1.5 and 1:15, or between 1:2 and 1:10 or between 1:2 and 1:5.

Abstract: A FCC process including the steps of (a) adding a crude lignin oil (CLO) to a FCC unit, wherein the FCC unit has a FCC riser, a catalyst regenerator and a reactor/stripper, wherein CLO is a crude lignin oil composition including lignin and a polar organic solvent in 1:10 to 1:0.3 w/v ratio, (b) optionally adding a second feed including a conventional FCC feedstock to the FCC unit, (c) adding a regenerated catalyst from the regenerator to the FCC riser for catalytic cracking and upgrading the CLO and second feedstock to produce upgraded products and deactivated catalyst, (d) adding the upgraded products and deactivated catalyst from the FCC riser to the reactor/stripper and separating upgraded products from deactivated catalyst in the reactor/stripper, (e) adding the deactivated catalyst from (d) to the regenerator to regenerate the deactivated catalyst to provide regenerated catalyst; and collecting the upgraded products.
