Light Hydrocarbon Aromatization Technology (LHAT)

  • Introduction
  • Technical Characteristics

Introduction

LHAT is a light hydrocarbon aromatization process developed by Sinopec. This process adopts modified H-HZSM-5 as catalyst and fits for converting C2~C5 light hydrocarbon feedstock to aromatics mainly in BTX or aromatics-rich gasoline blending component with high octane number. LHAT process has a series of advantages, such as high feed adaptability, high value-added target products, simple process flow and low construction investment cost.

Technical Characteristics

1. Operation flexibility
Sinopec’s light hydrocarbon aromatization process is flexible in operation. Aromatics oriented scheme, feed for ethylene plant oriented scheme or gasoline oriented scheme can be selected conveniently based on market demand.
LHAT-F process is simple and the investment is low. As a high impurity resistant catalyst is applied, the strict feed purification procedure to remove sulfur is not needed, which further lowers investment and operation costs.
In LHAT-M process, the catalyst is continuously regenerated, thus unstable problems caused from the intermittent reaction and catalyst regeneration in a fixed bed reactor can be avoided and the catalyst can always maintains high activity.
2. Feed adaptability
The main feedstock of the light hydrocarbon aromatization process includes C2 in FCC dry gas, C3 and C4 in refinery gas and some C5 and C5+ in light naphtha.
LHAT-F process is mainly used for the production of gasoline blending components with high octane number. Suitable feeds are mainly olefin contained FCC dry gas and LPG, as well as light naphtha. The gasoline yield varies based on feeds properties.
For LHAT-M process, feeds are mainly LPG and light naphtha. The main products are mixed aromatics or saturated LPG that can be used as feed of ethylene plants.
