New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

Researchers in Sweden and Spain have devised a three-step process for the conversion of precipitated kraft lignin from black liquor into green diesel. This makes black liquor the fifth most important fuel in the world, next to coal, oil, natural gas, and gasoline. Their paper appears in the journal ChemSusChem.

All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

It relies heavily on kerosene (jet fuel)—a liquid hydrocarbon fuel typically derived from crude oil. (A) In 2017, the team started scaling up the design and built a solar fuel-production plant at IMDEA Energy Institute in Spain. Zoller et al.

New Process Boosts Gasoline Production from the Catalytic Cracking of Vegetable Oil Under Refinery Conditions

Green Car Congress

Researchers at TU Delft (The Netherlands) and Universidad Rey Juan Carlos (Spain) have developed a new concept to increase the efficiency of the catalytic cracking of unsaturated vegetable oil to greatly increase the production of gasoline and light olefins (propene and butenes).

New simple, energy-efficient process for the direct production of renewable diesel from biomass waste

Green Car Congress

Non-edible carbohydrates are converted to renewable diesel-range liquids via two consecutive catalytic steps. A team at the Universidad Politécnica de Valencia (Spain) has designed a new simple, energy-efficient process (that also does not require any organic solvents) for the production of renewable diesel from biomass waste.

Researchers optimize production of high-quality transportation fuels from LDPE plastics

Green Car Congress

Researchers in Spain have obtained high-quality transportation fuels (gasoline with RON >80 and diesel with cetane number >70) from oil obtained by the thermal cracking of low-density polyethylene (LDPE) using a bifunctional catalyst comprising Ni (7 wt %) deposited on a hierarchical Beta zeolite (Ni/h-Beta).

Refineries in the Americas produce a greater share of gasoline per barrel of crude oil than refineries in other world regions

Green Car Congress

The International Energy Agency’s Monthly Oil Statistics shows that there are differences in refinery output throughout the world. Conversely, in Europe, diesel accounted for 40% of the petroleum refined versus about 30% for the Americas and Asia Oceania.

High-density renewable jet fuel from eucalyptus

Green Car Congress

The researchers were able to create a high yield of the cyclic hydrocarbon p -menthane from eucalyptus oil. For instance, UOP/Honeywell and Neste developed the hydrogenated esters and fatty acids (HEFA) processes to upgrade vegetable oils and animal fats to renewable jet/diesel fuels. Spain, Brian J.
