            "text" => "<p><strong>Решение</strong></p><p>Первичная переработка нефти — это физический процесс её разделения на фракции (компоненты), которые отличаются друг от друга температурами кипения. Этот процесс не затрагивает химическую структуру углеводородов, входящих в состав нефти. Основным методом первичной переработки является фракционная перегонка, или ректификация.</p><p>Процесс происходит в ректификационной колонне. Сырую нефть нагревают в печи до температуры около $350-370^\circ C$ и в виде смеси жидкости и пара она поступает в колонну. Внутри колонны пары поднимаются вверх, постепенно охлаждаясь. На разных уровнях (так называемых тарелках) колонны конденсируются различные фракции углеводородов в зависимости от их температур кипения.</p><p>В результате первичной переработки нефти (атмосферной перегонки) получают следующие основные продукты, которые называются нефтяными фракциями. Они перечислены ниже в порядке возрастания температуры кипения (от самых летучих к самым тяжелым):</p><ul><li><strong>Нефтяные (попутные) газы:</strong> Смесь легких углеводородов (метан $CH_4$, этан $C_2H_6$, пропан $C_3H_8$, бутан $C_4H_{10}$). Температура кипения ниже $40^\circ C$. Используются как газообразное топливо и как ценное сырьё для химического синтеза. </li><li><strong>Бензиновая фракция (нафта):</strong> Смесь углеводородов от $C_5H_{12}$ до $C_{12}H_{26}$. Температура кипения от $40^\circ C$ до $200^\circ C$. После дополнительной обработки (риформинга, изомеризации) из этой фракции получают автомобильный бензин. </li><li><strong>Лигроиновая фракция:</strong> Смесь углеводородов от $C_8H_{18}$ до $C_{14}H_{30}$. Температура кипения от $150^\circ C$ до $250^\circ C$.

Этот процесс не затрагивает химическую структуру углеводородов, входящих в состав нефти. Основным методом первичной переработки является фракционная перегонка, или ректификация.</p><p>Процесс происходит в ректификационной колонне. Сырую нефть нагревают в печи до температуры около $350-370^\circ C$ и в виде смеси жидкости и пара она поступает в колонну. Внутри колонны пары поднимаются вверх, постепенно охлаждаясь. На разных уровнях (так называемых тарелках) колонны конденсируются различные фракции углеводородов в зависимости от их температур кипения.</p><p>В результате первичной переработки нефти (атмосферной перегонки) получают следующие основные продукты, которые называются нефтяными фракциями. Они перечислены ниже в порядке возрастания температуры кипения (от самых летучих к самым тяжелым):</p><ul><li><strong>Нефтяные (попутные) газы:</strong> Смесь легких углеводородов (метан $CH_4$, этан $C_2H_6$, пропан $C_3H_8$, бутан $C_4H_{10}$). Температура кипения ниже $40^\circ C$. Используются как газообразное топливо и как ценное сырьё для химического синтеза. </li><li><strong>Бензиновая фракция (нафта):</strong> Смесь углеводородов от $C_5H_{12}$ до $C_{12}H_{26}$. Температура кипения от $40^\circ C$ до $200^\circ C$. После дополнительной обработки (риформинга, изомеризации) из этой фракции получают автомобильный бензин. </li><li><strong>Лигроиновая фракция:</strong> Смесь углеводородов от $C_8H_{18}$ до $C_{14}H_{30}$. Температура кипения от $150^\circ C$ до $250^\circ C$. Используется как топливо для тракторов, а также как растворитель в лакокрасочной промышленности. </li><li><strong>Керосиновая фракция:</strong> Смесь углеводородов от $C_{12}H_{26}$ до $C_{18}H_{38}$.

Решение

Первичная переработка нефти — это физический процесс её разделения на фракции (компоненты), которые отличаются друг от друга температурами кипения. Этот процесс не затрагивает химическую структуру углеводородов, входящих в состав нефти. Основным методом первичной переработки является фракционная перегонка, или ректификация.

Процесс происходит в ректификационной колонне. Сырую нефть нагревают в печи до температуры около $350-370^\circ C$ и в виде смеси жидкости и пара она поступает в колонну. Внутри колонны пары поднимаются вверх, постепенно охлаждаясь. На разных уровнях (так называемых тарелках) колонны конденсируются различные фракции углеводородов в зависимости от их температур кипения.

В результате первичной переработки нефти (атмосферной перегонки) получают следующие основные продукты, которые называются нефтяными фракциями. Они перечислены ниже в порядке возрастания температуры кипения (от самых летучих к самым тяжелым):

  • Нефтяные (попутные) газы: Смесь легких углеводородов (метан $CH_4$, этан $C_2H_6$, пропан $C_3H_8$, бутан $C_4H_{10}$). Температура кипения ниже $40^\circ C$. Используются как газообразное топливо и как ценное сырьё для химического синтеза.
  • Бензиновая фракция (нафта): Смесь углеводородов от $C_5H_{12}$ до $C_{12}H_{26}$. Температура кипения от $40^\circ C$ до $200^\circ C$. После дополнительной обработки (риформинга, изомеризации) из этой фракции получают автомобильный бензин.
  • Лигроиновая фракция: Смесь углеводородов от $C_8H_{18}$ до $C_{14}H_{30}$. Температура кипения от $150^\circ C$ до $250^\circ C$. Используется как топливо для тракторов, а также как растворитель в лакокрасочной промышленности.
  • Керосиновая фракция: Смесь углеводородов от $C_{12}H_{26}$ до $C_{18}H_{38}$. Температура кипения от $180^\circ C$ до $300^\circ C$. Основное применение — топливо для реактивных двигателей (авиационный керосин), а также осветительный керосин и топливо для бытовых нагревательных приборов.
  • Дизельная фракция (газойль): Смесь углеводородов с температурой кипения от $200^\circ C$ до $360^\circ C$. Является основным компонентом дизельного топлива для дизельных двигателей.
  • Мазут: Тяжелый остаток после отгонки всех вышеперечисленных фракций. Температура кипения компонентов мазута превышает $360^\circ C$. Это вязкая жидкость темного цвета. Мазут используют как котельное топливо, а также направляют на дальнейшую, более глубокую переработку.

Мазут, в свою очередь, подвергают вакуумной дистилляции (перегонке при пониженном давлении), чтобы избежать термического разложения (крекинга) тяжелых углеводородов. В результате из мазута получают:

  • Смазочные масла: Различные виды масел (моторные, трансмиссионные, индустриальные).
  • Парафин и церезин: Используются для производства свечей, в косметике, медицине, для пропитки бумаги и упаковки.
  • Гудрон: Конечный, самый тяжелый остаток перегонки. Используется для производства дорожного и строительного битума, кровельных материалов (рубероид).

Ответ: Продуктами первичной переработки нефти являются нефтяные газы, бензиновая фракция, лигроиновая фракция, керосиновая фракция, дизельная фракция и остаток — мазут. Мазут в дальнейшем перерабатывается на смазочные масла, парафин и гудрон.
