Embodiment 1-29

[0112] Examples 1-29 illustrate embodiments for gasifying carbonaceous materials when the carbonaceous materials contain no or negligible water and no direct addition of water or steam to the gasifier, and where the carbonaceous materials Embodiments of gasifying carbonaceous materials with large amounts of water and / or direct addition of large amounts of water or steam to the gasifier. These examples illustrate the gasification of single carbonaceous materials such as coal, coke oven tar (coke), plastics, tires, wood, polystyrene (PS), polyethylene terephthalate (PETA). Embodiments, and gasification of various carbonaceous materials such as blends of tires and wood, blends of plastics and wood, blends of plastics and msw, and blends of coke oven tar and fiber soft implementation. For all of these examples, the temperature in the first reaction zone was 1400°F and the temperature in the second reaction zone was 2250°F. The relevant carbonaceous material properties, other gas...

Abstract

The present disclosure is generally directed to process of gasification of carbonaceous materials to produce synthesis gas or syngas. The present disclosure provides improved methods of gasification comprising adding a molecular oxygen- containing gas and optionally adding water into said gasifier. This disclosure is also directed to process of production of one or more alcohols from said syngas via fermentation or digestion in the presence of at least one microorganism.

Description

technical field [0001] The present disclosure generally relates to methods of gasifying carbonaceous materials to produce synthesis gas or syngas. The present disclosure also relates to methods of producing one or more alcohols from said syngas via fermentation or digestion in the presence of at least one microorganism. Background technique [0002] The present disclosure contemplates the gasification of carbonaceous materials to produce carbon monoxide (CO), carbon dioxide (CO 2 ), and hydrogen (H 2 ) of synthetic gas. Syngas can be used to produce one or more chemical substances, either biologically or chemically. Syngas can also be used to generate energy to generate electricity. [0003] Therefore, the synthesis gas can be used to produce alcohol (methanol, ethanol, propanol, butanol, etc.), acetic acid, acetate, hydrogen, etc. through the fermentation or digestion of certain microorganisms. Several strains of acetogens have been described for the production of liqu...
