Abstrakt Modern petroleum geology is built on the theory of the organic origin of hydrocarbons. It is claimed that they are formed as a result of dipping of organic carbon-rich sedimentary layers and their thermal transformation by which hydrocarbons are generated. Conventional looking at the formation of hydrocarbons is based on buried in a sedimentation pool dead biomass of organisms and their long-lasting microbial degradation in an anaerobic environment with the simultaneous influence of temperature and pressure. This process creates a transformed organic material of high molecular weight called kerogen. About 1% of the live mass of the organic may be stored in kerogen in favorable conditions. Regardless of the type of kerogen, increasing temperature and pressure leads to the dissociation temperature or the cracking and forms a crude oil or natural gas. The secondary cracking at a higher temperature and pressure may result in the smallest particles of hydrocarbons, methane (Sephton, Hazen 2013). This theory does not answer the question of why there are massive accumulations of hydrocarbons reaching hundreds of millions of tons when their hitherto regarded as the mother layers, source rocks, is so little spread in the geological profile?

Hydrocarbons provide our core energy resource. Information on their origin, properties and phase behavior is interesting from the point of view of physical chemistry. At the same time this information is of great value to the oil and gas industry. The book "Hydrocarbon" is comprised of 9 chapters, covering different topics: from origin of hydrocarbons to the method for hydrocarbon exploration. Distribution of polycyclic aromatic hydrocarbons in soil and their influence to environment are also discussed. This book should serve as a support to researchers and students as well as experts, both in academia and industry.

Since the 3rd edition of this publication, emphasis within the petroleum industry has shifted from exploration to appraisal and development of existing hydrocarbon resources. This change is reflected in this new 4th edition, which has been significantly expanded to accomodate additional material. The centrepiece of the book, however, remains a series of descriptions, in stratigraphic order, of the depositional history and hydrocarbon related rock units of the North Sea.

Written by an author with over 38 years of experience in the chemical and petrochemical process industry, this handbook will present an analysis of the process steps used to produce industrial hydrocarbons from various raw materials. It is the first book to offer a thorough analysis of external factors effecting production such as: cost, availability and environmental legislation. An A-Z list of raw materials and their properties are presented along with a commentary regarding their cost and availability. Specific processing operations described in the book include: distillation, thermal cracking and coking, catalytic methods, hydroprocesses, thermal and catalytic reforming, isomerization, alkylation processes, polymerization processes, solvent processes, water removal, fractionation and acid gas removal. - Flow diagrams and descriptions of more than 250 leading-edge process technologies - An analysis of chemical reactions and process steps that are required to produce chemicals from various raw materials - Properties, availability and environmental impact of various raw materials used in hydrocarbon processing

Carbon in Earth's fluid envelopes - the atmosphere, biosphere, and hydrosphere, plays a fundamental role in our planet's climate system and a central role in biology, the environment, and the economy of earth system. The source and original quantity of carbon in our planet is uncertain, as are the identities and relative importance of early chemical processes associated with planetary differentiation. Numerous lines of evidence point to the early and continuing exchange of substantial carbon between Earth's surface and its interior, including diamonds, carbon-rich mantle-derived magmas, carbonate rocks in subduction zones and springs carrying deeply sourced carbon-bearing gases. Thus, there is little doubt that a substantial amount of carbon resides in our planet's interior. Yet, while we know it must be present, carbon's forms, transformations and movements at conditions relevant to the interiors of Earth and other planets remain uncertain and untapped. Volume highlights include: - Reviews key, general topics, such as carbonate minerals, the deep carbon cycle, and carbon in magmas or fluids - Describes new results at the frontiers of the field with presenting results on carbon in minerals, melts, and fluids at extreme conditions of planetary interiors - Brings together emerging insights into carbon's forms, transformations and movements through study of the dynamics, structure, stability and reactivity of carbon-based natural materials - Reviews emerging new insights into the properties of allied substances that carry carbon, into the rates of chemical and physical transformations, and into the complex interactions between moving fluids, magmas, and rocks to the interiors of Earth and other planets - Spans the various chemical redox states of carbon, from reduced hydrocarbons to zero-valent diamond and graphite to oxidized CO2 and carbonates - Captures and synthesizes the exciting results of recent, focused efforts in an emerging scientific discipline - Reports advances over the last decade that have led to a major leap forward in our understanding of carbon science - Compiles the range of methods that can be tapped tap from the deep carbon community, which includes experimentalists, first principles theorists, thermodynamic modelers and geodynamicists - Represents a reference point for future deep carbon science research Carbon in Planetary Interiors will be a valuable resource for researchers and students who study the Earth's interior. The topics of this volume are interdisciplinary, and therefore will be useful to professionals from a wide variety of fields in the Earth Sciences, such as mineral physics, petrology, geochemistry, experimentalists, first principles theorists, thermodynamics, material science, chemistry, geophysics and geodynamics.
