Assumption Park gives residents of this city lovely views of the Ambassador Bridge and the Detroit skyline. Lately they’ve been treated to another sight: a three-story pile of petroleum coke covering an entire city block on the other side of the Detroit River. Detroit’s ever-growing black mountain is the unloved, unwanted and long overlooked byproduct [...]

This study aims to quantify water appropriation and the potential production of algal bio-oil using freshwater and municipal wastewater effluent (MWW) as an alternative water resource. The county-level analysis focuses on open-pond algae cultivation systems located in 17 states in the southern United States. Several scenarios were developed to examine the water availability for algae [...]

Here’s the pattern: bend to public will when mandate efforts become popular, establish big projects, hire top R&D talent and bottle up IP to prevent technology spread, kill off the projects with absurd profit requirements, cite lack of feasible technology as a reason to kill or delay mandates, and then lobby like crazy to get [...]

This paper evaluates the economic feasibility of biohydrogen production via two bio-oil processing pathways: bio-oil gasification and bio-oil reforming. Both pathways employ fast pyrolysis to produce bio-oil from biomass stock. The two pathways are modeled using Aspen Plus® for a 2000 t d−1 facility. Equipment sizing and cost calculations are based on Aspen Economic Evaluation® [...]

Pyrolysis experiments of blue-green algae blooms (BGAB) were carried out in a fixed-bed reactor to determine the effects of pyrolysis temperature, particle size and sweep gas flow rate on pyrolysis product yields and bio-oil properties. The pyrolysis temperature, particle size and sweep gas flow rate were varied in the ranges of 300–700 °C, below 0.25–2.5 [...]

The absence of well-executed environmental monitoring in the Athabasca oil sands (Alberta, Canada) has necessitated the use of indirect approaches to determine background conditions of freshwater ecosystems before development of one of the Earth’s largest energy deposits. Here, we use highly resolved lake sediment records to provide ecological context to ∼50 y of oil sands [...]

The oil industry’s confidence leaves some researchers wary. “I think it’s incredibly premature,” says Sean Anderson, an ecologist at California State University Channel Islands in Camarillo, who is part of a group studying the spill1. “We’re in no way saying dispersants should never be used or didn’t work at all; it’s a question of, ‘Show [...]

Pipeline systems used to transport petroleum products represent a potential source of soil pollution worldwide. The design of new techniques that may improve current monitoring of pipeline leakage is imperative. This paper assesses the remote detection of small leakages of liquid hydrocarbons indirectly, through the analysis of spectral features of contaminated plants. Leaf and canopy [...]

Biodiesel has gained significant attention as an alternative to petroleum diesel. Currently, there is an increasing interest in obtaining microbial oils from oleaginous micro-organisms for biodiesel production. In the accumulation of microbial oils, carbon substrate constitutes a major portion of the cost. Accordingly, significant efforts have been made to explore suitable carbon sources, and to [...]

Using the marine rotifer Brachionus plicatilis acute toxicity tests, we estimated the toxicity of Corexit 9500A®, propylene glycol, and Macondo oil. Ratios of 1:10, 1:50 and 1:130 for Corexit 9500A®:Macondo oil mixture represent: maximum exposure concentrations, recommended ratios for deploying Corexit (1:10–1:50), 1:130 the actual dispersant:oil ratio used in the Deep Water Horizon spill. Corexit [...]
