The aim of the present investigation is to examine the potential utilization of Dried Olive Pomace (DOP) as an alternative fuel in cement clinkerization, determining the effects on the properties of the cement clinker produced, by substituting coal on the
1. Introduction. Biomass energy, or bioenergy, is considered as the fourth largest energy source (behind oil, coal and natural gas), accounting for about 14% of
Hydrochar yields of 65.3, 60.4 and 51.6% were measured at 200, 220 and 240 + C with 2 h residence time, similar to yields reported for HTC of olive pomace [55].
The calorific value of olive pomace is quite high and comparable to that of coal. Olive biomass releases considerable energy during it’s combustion and its calorific

The total soluble phenolics in dried ROR were in the range 0.15 to 0.58 mg gallic acid equivalents/g of dry weight for 2phase ROR, and 1.38 to 2.17 mg gallic acid
The effect on in vitro digestibility of treated crushed olive branches was very positive, especially when ammonia and soda were used together, as the effect of
Valorization of Dried Olive Pomace as an alternative fuel. Oct 30, · The aim of the present investigation is to examine the potential utilization of Dried Olive Pomace (DOP)
Pulverized Coal Preparation System. 1.The raw coal from storage and conveying system come into air swept coal mill for grinding. The coal powder mass and heat transfer with
Apr 03, · Steam coal is primarily used in power generation, while coking coal is used mainly in steel production. The five largest users of coal are China, India, the United
A schematic process flow diagram of the integrated gasification plant is presented in Fig. 2.The proposed plant consists of a pelletizing machine or pelletizer, a downdraft fixed bed gasifier fueled with dried olive pomace pellets, a producer gas cooling and cleaning unit, a microturbine for electric power generation and a cocurrent flow
Olive pomace as a byproduct of the olive oil production process is a significant biomass source. biomass gasification was still much more environmentally friendly than the coalfired one. Valente et al. [30] worked on the life cycle sustainability assessment (LCSA) of hydrogen from biomass gasification. Although the hydrogen
Part of the additional production is driven by a need to reduce the country’s dependence on coal imports, which are expected to drop by 51 million tonnes or 16% from –2024. By 2024, China’s coal
Romeo M. Flores, in Coal and Coalbed Gas, 2014 Historical Coal Production. Coal production dates back to the earliest civilizations cited by Aristotle (340) and Agricola (1556) for use in fire combustion during the middle of the fourth century B.C. (Landis & Weaver, 1993).It was thought that the Chinese first commercialized coal production for smelting
The hard coal consumption of the EU is estimated to have reached 160 million tonnes, 27 % less than three years earlier. Production of hard coal in the EU has decreased almost continuously from 1990, more consistently than consumption. In , the EU production was 57 million tonnes, 79 % less than the 277 million tonnes of 1990.
ness. According to the International Olive Oil Council, world production and consumption are in rough balance around 2.8 tons of olive oil per year. Production peaked several years ago at more than 3 million tons, but has dropped slightly in recent years. The World Olive Council expects a crop of 3 million tons in 2011.
In –19, Australia’s production of saleable black and brown coal was 13,038 PJ, which accounted for 66 per cent of total energy production (excluding uranium production; Department of Industry, Science, Energy and Resources, a). Over the past decade, coal production has grown by an average annual rate of 3 per cent, moderated
Dry olive stone . The oliveoil mill bone is obtained by separating the bone from the olive pulp. The separation is usually carried out in oliveoil mills by physical procedures, being used as fuel in different phases of olive processing. Subsequently, the bone is dried, leaving a solid substance with humidity below 15%.
Then, BC was dried in an oven at 60°C to constant weight . The dried cellulose pellicles were used for determining their characterization (FTIR, TGA, XRD and SEM). Dried BC samples were analyzed by using an FTIR spectrometer (BioRad Tropical Option for FTS 175C) in the range of 4000–600 cm −1 .
The effect on in vitro digestibility of treated crushed olive branches was very positive, especially when ammonia and soda were used together, as the effect of ammonia seemed to be greater besides considerably increasing the digestible crude protein content.. The same authors repeated this experience, treating 5–6 ton stacks of crushed
Olive pomace as a byproduct of the olive oil production process is a significant biomass source. biomass gasification was still much more environmentally friendly than the coalfired one. Valente et al. [30] worked on the life cycle sustainability assessment (LCSA) of hydrogen from biomass gasification. Although the hydrogen
Boudhrioua et al. used infrared to dry the olive leaves and calculated the drying rate . Erbay and Icier determined the energy utilization during the thinlayer drying of olive leaves in the tray dryer [2, 12]. This study is the first to investigate the drying behaviour of olive leaves dried by microwave, vacuum and oven methods.

We expect global coal demand to fall by about 8% in , the largest drop since World War II, with coal use declining in virtually every sector of every region in the world. In China, coal demand will decline in by around 5%, despite the gradual recovery since February lockdown. Coalfired power generation will be hit especially hard, because the power
Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coalor gasfired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

The U.S. Energy Information Administration estimates (as of October ) that in , CO 2 emissions from burning coal for energy accounted for about 20% of total U.S. energyrelated CO 2 emissions and for nearly 60% of total CO 2 emissions from the electric power sector. In the past, fly ash was released into the air through the
The high temperature (700–900°C) air or the exhaust gases are used in the conventional evaporative dryers .In the power plants, the exhaust gases can be used in the drying process, so the overall
The coal industry is a component of the fuel and energy sector of the Russian Federation. Strategies for the industry’s development depend on the position of coal in the country’s fuel and energy balance. The energy and fuel consumption of the Russian economy differs greatly from world practice, as it is mainly based on natural gas (53.1%).
