Second generation biofuels, especially fuels from lignocellulose biomass, which are manufactured from non-food feedstock play a key role to reduce greenhouse gas emissions and the dependency on fossil oil. The bioCRACK process represents a new biomass-to-liquid concept to generate advanced biofuel by liquid-phase pyrolysis. As liquid heat carrier vacuum gas oil (VGO), an intermediate heavy oil ...

The city of Zarghan is located 25 km northeast of Shiraz, southern Iran. Zarghan is affected by numerous pollution sources such as oil refinery, an industrial park, and Shiraz-Tehran highway. The numerous contaminating sources around Zarghan can cause serious local air pollution. Sulfur dioxide gas is an important index of air pollution in cities. Therefore, in order to control and manage Zargh...

It is a great challenge to find efficient tools for shortterm scheduling of oil refinery processes. Although some, theoretical advancement has been made in this field, a gap between theory and applications exists. In practice, the short-term scheduling job of oil refinery processes is still done manually by planners, because of the lack of such tools. This paper briefly introduces the productio...

Fast catalytic pyrolysis of wild reed was carried out at 500 ̋C. Waste fluidized catalytic cracking (FCC) catalyst disposed from a petroleum refinery process was activated through acetone-washing and calcination and used as catalyst for pyrolysis. In order to evaluate the catalytic activity of waste FCC catalyst, commercial HY zeolite catalyst with a SiO2/Al2O3 ratio of 5.1 was also used. The b...

Qingyu Feng. M.S.A.B.E., Purdue University, December 2013. Biomass Production and Hydrological/Water Quality Impacts of Perennial Crop Production on Marginal Land. Major Professor: Indrajeet Chaubey. Marginal land has been proposed to be a viable choice for biomass production to meet the biofuel development goal set by Energy Independence and Security Act (EISA). However, very little informatio...

Catalytic hydrotreating is an attractive method for upgrading bio-derived oils into renewable feedstocks with less oxygen content, suitable for producing valuable hydrocarbons through various petro-refinery processes. This study evaluates the catalytic activity of a commercial alumina (Al2O3) supported NiMo catalyst for hydrotreating tall oil feeds such as crude tall oil (CTO), distilled tall o...

Plant biomass is considered as an important renewable resource for future bioenergy needs. Cell walls, which are typically highly recalcitrant, constitute the major part of this biomass. Overcoming the cell wall recalcitrance is considered as a major bottleneck towards achieving a highly sustainable and cost-effective production of biofuels from ligno-cellulosic materials [1]. Cell wall compone...

background: blood hemoglobin can be damaged by toxins such as lead. thus, this study was carried out to assess its blood hemoglobin concentration in the staff of kermanshah oil refinery that had been exposed to lead components. methods: in this study, 150 workers at kermanshah oil refinery were selected as the case group and 70 workers of textile industry factory were chosen as the control grou...

0 A tremendous amount of material has been written about wastewater treatment and reuse in recent years. This is partly due to the constantly changing technology in the field. Controversy surrounding the promulgation of regulations by the Environmental Protection Agency (EPA), and subsequent revisions, have added to the confusion. The purpose of this article is to attempt to tie this mass of in...
