Disclosed are methods of producing calcined coke from bio-oil from a biomass feedstock. Also disclosed are calcined cokes produced by such methods.

Methods of producing calcined coke from bio-oil and calcined coke produced thereby

Methods for producing bio-oil from a feedstock (e.g., lignocellulosic) involving (1) pyrolyzing the feedstock in an inert atmosphere in a reactor to produce bio-oil, bio-char and non-condensable gases; (2) recycling 50 to about 85% of the non-condensable gases to the reactor to produce deoxygenated bio-oil; wherein the method is conducted in the absence of oxygen and wherein the method does not utilize externally added catalysts.

Methods for producing bio-oil

A pyrolyzer apparatus (i.e. a 'cracking pipe') comprises a first screen, a second screen, and a catalyst material positioned between the first and second screens. The pyrolyzer is structured so that feedstock is pyrolyzed and pyrolyzer-generated gas is drawn through the first screen, through the catalyst material, and then through the second screen in series. The gas may then be directed to other processing equipment so that bio-oil is extracted from the gas.

Fast pyrolysis catalytic cracking pipe for producing bio-oils

Bio-oil from a feedstock selected from mustard family seeds, mustard family seed presscake, mustard family seed defatted presscake, and mixtures thereof. The bio-oil is produced by a method involving (1) pyrolyzing the feedstock to produce bio-oil, bio-char and non-condensable gases, (2) removing the bio-char from the bio-oil, (3) condensing the bio-oil, and (4) precipitating the bio-oil.
