The pilot plant test results showed that the RSDS-III technology could be adapted to different feedstocks. The sulfur content dropped from 600 μg/g and 631 μg/g to 7 μg/g and 9 μg/g, respectively, by RSDS-III technology when feed A and feed B were processed to meet China national V gasoline standard, with the RON loss of products equating to 0.9 units and 1.0 unit, respectively. While the feed C with a medium sulfur content was processed according to the full-range naphtha hydrotreating technology, the sulfur content dropped from 357 μg/g in the feed to 10 μg/g in gasoline, with the RON loss of product decreased by only 0.6 units. Thanks to the high HDS activity and good selectivity of RSDS-III technology, the ultra-low-sulfur gasoline meeting China V standard could be produced by the RSDS-III technology with little RON loss.展开更多

To identify and understand the resources based on the possessed knowledge, steps for development are proposed. But, no less important is to understand the surrounding, what others are doing/planning, as it will save precious time in inventing something which is maybe already implemented elsewhere. Based on that assumption, this paper deals with the analysis of the current status of the organic farming （O.F.） in Macedonia and the Mediterranean countries, as they are closest to the soil and climate conditions that exist in Macedonia as well. This paper will try to give answer to the question ＂how to maintain the present level of development and to set parameters which should be used in order to reach further development＂. The analysis process was implemented by using SWOT （strength, weakness, opportunity, and threats） analysis for Macedonia and the Mediterranean countries. The analysis result indicates that there are numerous common factors, resources, structures, and gaps in the organic sector. This paper＇s goal is to present a list of strategic goals and instruments for development of O.F. in Macedonia and Mediterranean countries. The data related to the facts and visions are referred to the Republic of Macedonia, but relevant data on EU countries, candidate-countries, and south Mediterranean countries are presented as well. The conclusions are with special accent to the new possibilities for development of O.F. in the near future, especially through applicative scientific research activities.展开更多
