  • Patent number: 9206367
    Abstract: Plant or animal oils are processed to produce a fuel that operates at very cold temperatures and is suitable as an aviation turbine fuel, a diesel fuel, a fuel blendstock, or any fuel having a low cloud point, pour point or freeze point. The process is based on the cracking of plant or animal oils or their associated esters, known as biodiesel, to generate lighter chemical compounds that have substantially lower cloud, pour, and/or freeze points than the original oil or biodiesel. Cracked oil is processed using separation steps together with analysis to collect fractions with desired low temperature properties by removing undesirable compounds that do not possess the desired temperature properties.

  • Patent number: 8450541
    Abstract: A method for producing products containing cyclic organic compounds from biomass oil includes adding a biomass oil to a vessel; heating the biomass oil to crack the biomass oil; removing undesired or unreacted materials, heavy ends, and light ends from the cracked biomass oil; and extracting components from the cracked biomass oil to produce a mixture of products containing between 5% and 90% cyclic organic compounds by weight. A method for producing a high-octane aviation fuel with low lead content includes cracking a biomass oil, separating a middle distillate mixture from cracked biomass oil, decarboxylating the middle distillate mixture to produce a mixture of products containing at least about 50% cyclic alkane and alkene compounds by weight, and blending the mixture of products with a fuel having an octane number below 95 to produce an aviation fuel having an octane number of at least 100.

  • Patent number: 8076504
    Abstract: A method for producing a mixture of short chain carboxylic acids from biomass includes adding biomass to a reactor vessel, heating the biomass to crack it, removing undesired and unreacted materials and light ends from the cracked biomass, and removing a mixture containing carboxylic acids having carbon chain lengths between C2 and C16. A composition includes a carboxyl group-containing compound derived by cracking biomass and having a carboxyl carbon chain length between C2 and C16.

  • Patent number: 8012242
    Abstract: A method of removing pollutants from building materials using an externally applied adsorbent. The adsorbent has a high affinity to common pollutant chemicals. The pollutants are transferred from the contaminated microporous building materials onto the adsorbent until sufficient amounts of pollutant chemicals are reduced to make the building materials acceptable and safe to use. The adsorbent may be regenerated and reused or treated as a waste.

  • Publication number: 20090280030
    Abstract: A method and apparatus automates and accelerates the extraction and analysis of trace elements from biomass. The method and apparatus are especially useful at key segregation points in the food chain where speed and accuracy is necessary to separate agricultural cereals that are elevated in beneficial trace element content which provides higher value to the producer.
