A method for improving a reforming process by using renewable electrical energy as a heating input to the reforming process is provided. The method includes partially preheating combustion air using a first electrical heater, wherein the first electrical heater is configured to be supplied with the renewable electrical energy generated by a renewable source, wherein the first electrical heater is integrated in between a cold air preheater and a hot air preheater of a process plant that performs the reforming process; utilizing, by the first electrical heater, a bad based on an availability of the renewable electrical energy received from the renewable source; and providing, by the first electrical heater, the preheated combustion air at an outlet of the first electrical heater to a boiler of the process plant based on the bad utilized by the first electrical heater.

Disclosed herein are aluminum oxide aerogels and methods of making and use thereof. The methods of making the aluminum oxide aerogel include contacting a solid comprising aluminum with a Ga-based liquid alloy to dissolve at least a portion of the aluminum from the solid, thereby forming an aluminum-alloy mixture; and contacting the aluminum-alloy mixture with a fluid comprising water, thereby forming the aluminum oxide aerogel. In some examples, the methods can further comprise capturing and converting carbon dioxide to a syngas comprising carbon monoxide and hydrogen.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.
