A team from the University of Vaasa (Finland) and UPM-Kymmene Corporation has examined how the blends of fossil and renewable diesel produced from crude tall oil (CTO) affect the performance and exhaust emissions of the modern common-rail off-road diesel engine. UPM BioVerno renewable diesel is produced from wood-based tall oil.

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. Typically, wells are abandoned after they are no longer producing oil or gas at a rate that is economically viable. It is very basic research at the simplest chemical level.

Less refined fuels—such as heavy gas oil—would be less expensive; however, the higher levels of sulfur in the fuels could prove problematic for catalysts. One approach to overcoming such limitations is the use of direct reforming of gas oil (heavy hydrocarbons) over a heteroatom-resistant catalyst. Now, researchers in S.
