Project combines biomass, solar for synthetic fuel

Technology Review -- Weimer, a former Dow Chemical engineer, says the system is "agnostic" to the types of biomass it can process. "It's like a sledgehammer because of the (1,200 to 1,300 ºC) temperatures it operates at," he says, explaining that conventional gasification uses lower temperatures to try to minimize the volume of biomass used to fuel the process. But keeping the temperature lower poses another problem. Gasification at temperatures below 1,000 ºC leaves behind tar. "And that tar is expensive to get rid of," says Weimer. "If you leave it in there, it will end up killing your catalysts downstream when you try to reform your product into (liquid) fuel."

teafortwo asks:

"I wonder if this process can be applied to garbage and landfill waste?"

From claim that: 'says the system is "agnostic" to the types of biomass it can process.'

I would assume so. But the costs of separating the suitable biomass from the other trash could be a killer, as could the costs of transporting the biomass, which kills most biomass projects. At least this finds a way to turn some solar energy into usable fuel.

Follow the science.

Conserve and support alternatives.

I wonder if this process can be applied to garbage and landfill waste?

Thanks for sharing E-Squirrel ;0)

FROM THE ARTICLE:

A solar-driven process could yield far more fuel than conventional biomass production.

Sundrop Fuels, a startup based in Louisville, CO, says it has developed a cleaner and more efficient way to turn biomass into synthetic fuels by harnessing the intense heat of the sun to vaporize wood and crop waste. Its process can produce twice the amount of gasoline or diesel per ton of biomass compared to conventional biomass gasification systems, the COmpany claims.

Gasification occurs when dry biomass or other carbon-based materials are heated to above 700 ºC in the presence of steam. At those temperatures, most of the biomass is COnverted to a synthetic gas. This "syngas" is made up of hydrogen and carbon monoxide, which are the chemical building blocks for higher-value fuels such as methanol, ethanol, and gasoline.
