With 110-d incubation experiment in laboratory, the responses of microbial quantity, soil enzymatic activity, and bacterial community structure to different amounts of diesel fuel amendments were studied to reveal whether certain biological and biochemical characteristics could serve as reliable indicators of petroleum hydrocarbon contamination in meadow-brown soil, and use these indicators to ...

Conventional asphalt binder derived from the petroleum refining process is widely used in pavement engineering. However, asphalt binder is a non-renewable material. Therefore, the use of a co-production of renewable bio-oil as a modifier for petroleum asphalt has recently been getting more attention in the pavement field due to its renewability and its optimization for conventional petroleum-ba...

Biomass has been offered as a sustainable replacement to fossil fuels since it can be converted into chemicals and liquid fuels. Recent years have seen surge in interest the feasibility of combining biomass rapid pyrolysis bio-oil catalytic upgrading produce biofuels. There would no progress this process without catalysts. Although achieved, problems with catalyst selectivity inactivation persi...

The Front Cover picture shows the growth of strategic polyolefin catalyst research since 1990 in Interdisciplinary Research Center for Refining & Advanced Chemicals (IRCRAC) at Institute King Fahd University Petroleum Minerals, Dhahran, Saudi Arabia. Our vision is to transform Arabia into an international hub and leader education, research, training, manufacturing, application, business. See Pe...
