PETCOKE
Also know as petroleum cokepetcoke is produced through the refining of petroleum and contains a high proportion of carbon. It is a form of solid carbon produced by means of heat decomposition and polymerization of heavy liquid hydrocarbons derived from the refining of crude. There are many commercial varieties of petcoke with different physical and chemical characteristics being used in different industrial applications, depending on the method of industrial production used to obtain it. The most common production methods used are:
Green delayed coking
a method of cracking in which the carbonization reactions involve dehydrogenization, restructuring and polymerization. The working temperature fluctuates between 480ºC and 500ºC and a complete production cycle takes at least 16 hours.
Fluid coking
is a continuous process of pulverization at high temperatures on a fluid surface in which the coke particles are maintained at a pressure of between 20-40 psi and 500ºC. These feed vapors are subjected to heat cracking while they are being deposited, forming a liquid film on reheated coke particles, finally becoming nucleant agents. Thus, the particles grow in layers until they can finally be removed. Finally, another layer of nucleant coke particles is added to the system.

MICRONIZED PETROLEUM COKE (PETCOKE)
Micronized petcoke is an evolved version of petroleum coke. Thanks to the micronization system, a process developed by our organisation more than 10 years ago, the coke is provided with the optimal properties for use.
Broadly speaking, the process consists of drying and grinding the coke down to a size of 90 to 500 microns. This improves the fuel’s properties, allowing for better combustion in the furnace and reducing unburned coke.
These properties mainly revolve around homogenising the product in size and moisture content and increasing its calorific value, thus allowing for greater stability in the combustion processes for which it is used.
In addition, its form provides benefits over liquid or gas fuels in terms of supply and storage.

ANTHRACITE
This mineral is extracted directly from the mines and contains a high proportion of carbon, low volatility and low sulfur content, which give it excellent properties for use in reduction processes or as a source of energy.
Depending on the origin of the mining basin, there are three types of anthracite:
Low volatiles content
This type of anthracite is especially suitable for carbon/reduction contribution, such as steel, metal and chemicals
Medium volatile content
Particularly indicated for domestic use, both for its ash content and its higher volatile level, although it can be used in industry.
High content of volatile
Particularly indicated for domestic use.

BIOMASS
Biomass is the organic material used as an alternative energy source to fossil fuels. There are several types of biomass derived from forest residues and agricultural residues, such as wood pellets, olive and fruit by-products (pomace, treated bones, shells and flours), products that are processed to obtain the highest energy efficiency from them and without negative impact on our environment
Being a renewable energy, it is an inexhaustible resource.
It comes from natural agricultural surpluses that are recycled.
It does not have a significant environmental impact (neutral CO2).
Helps reduce the risk of forest fires.
Wood pellets for domestic use
The wood pellet with ENPlus A1 quality certificate is a type of biomass or ecological energy raw material produced with 100% pine. It does not contain additives. Therefore, in its combustion there is no presence of harmful emissions.
